Comparison
Openbook vs Smartsheet
Smartsheet deserves respect for what it built: a spreadsheet interface that grew into a full work management platform trusted by a large share of the world's biggest companies. Anyone who can use Excel can open a sheet and start working, and underneath that familiar grid sit capabilities Excel never had: cross-sheet formulas and cell linking, no-code automation workflows, approval chains, forms that feed rows directly into sheets, and the ability to flip the same data between grid, Gantt, card, and calendar views. For project management offices coordinating hundreds of projects with real budgets and real deadlines, Smartsheet is a serious, proven tool, and it has been refining this formula for roughly two decades with the enterprise features to show for it.
But Smartsheet is a project management engine, not a team workspace. There is no chat, no document editor, no wiki, and no place to ask a question and get an answer that outlives the moment. Conversation happens in row comments or leaves for email and Slack, and knowledge lives wherever it happens to land. The platform's most powerful capabilities, the ones enterprise buyers actually want, are frequently sold as premium add-ons priced on top of per-user licenses, and its AI features have generally been reserved for higher tiers. Teams end up running Smartsheet for the plan and three or four other tools for everything around the plan, which is exactly the fragmentation a work platform was supposed to solve.
Openbook approaches the same problem from the workspace side. Its Table Board room ships with roughly 78 templates and covers structured tracking; Gantt, Kanban with sprints, and Dashboard rooms cover planning and reporting. Around that core sit 14 more room types: Chat with channels and DMs, Docs and Wiki on a modern BlockNote editor, a Q&A room with votes and accepted answers, Check-ins for async standups with mood tracking, real-time Retrospectives, a multiplayer Whiteboard, pixel-pinned Proofing for creative review, Time Off tracking with approvals and capacity, a social Feed, Events with RSVPs, and company-wide Townhalls. The plan and everything around the plan live in one workspace, searchable from a single command-K, under one exact-seat bill.
This comparison tries to be honest about the trade. Smartsheet's formula engine, its automation depth, and its enterprise portfolio tooling are genuinely stronger than anything Openbook offers, and teams whose work is fundamentally spreadsheet-shaped should read the sections below where we say exactly that. But if your team uses a tenth of Smartsheet's power and still pays for a chat tool, a docs tool, and a standup bot beside it, the comparison changes shape entirely. We walk through what each product does well, a feature table, pricing, AI capabilities, migration questions, and who should pick which tool, with as few weasel words as we can manage, so the decision rests on facts rather than fog.

Credit where due: what Smartsheet does well
Spreadsheet power that Excel users already understand
Smartsheet's core insight was that the grid is the most widely understood interface in business software. Its sheets support formulas, cross-sheet references, and cell linking, so a portfolio roll-up can pull live numbers from dozens of project sheets, something no kanban tool does natively. Hierarchy rows, predecessors, and dependency-driven Gantt charts make it a legitimate scheduling engine rather than a spreadsheet with a paint job. For operations and PMO teams whose work genuinely is rows, dates, and calculated values, that engine is the product's spine, and it remains stronger than what most modern work platforms, Openbook included, offer in a table view. That is a real advantage and it is theirs.
Serious no-code automation and forms
Smartsheet's automation builder is one of the most capable in the category: alerts, approval requests, recurring reminders, and multi-step workflows that update rows, move them between sheets, and request sign-offs, all configured without writing code. Forms are a quiet superpower, letting anyone submit structured data that lands as a row, which makes Smartsheet a common backbone for intake processes: project requests, expense submissions, incident reports. Combined with conditional logic and update requests sent to people outside the system, these tools let operations teams automate real business processes rather than just notifications, and many organizations run genuinely critical workflows on them every day without a developer in sight.
Enterprise portfolio and resource management
At the top end, Smartsheet plays in territory most work tools never reach. Control Center provisions and standardizes hundreds or thousands of projects from blueprints and rolls them up into portfolio-level reporting; Dynamic View and Data Shuttle handle filtered external sharing and data pipelines; and its resource management capability tracks who is allocated where across a whole organization. Dashboards aggregate metrics across many sheets into executive views. These are premium add-ons with real price tags, but for a PMO coordinating a program across departments and quarters, they solve problems smaller tools cannot touch, and they are a large part of why enterprises standardize on Smartsheet in the first place.
Governance and enterprise trust
Smartsheet has spent two decades becoming procurement-safe. It offers the admin controls, security certifications, and audit capabilities large organizations require, and it is already approved inside a huge number of enterprises, which makes expanding its footprint frictionless compared with introducing a brand-new vendor. Its user community, training resources, and partner ecosystem are mature, and administrators can hire people who already know the platform well. For a company where every new tool must pass security review and vendor management before anyone touches it, that incumbency is worth real money, and any honest comparison has to weigh it alongside the feature list rather than pretending features are the whole decision.
Where Openbook wins
A workspace, not a sheet with views
Smartsheet answers one question extremely well: what is the state of the plan? Openbook answers that one and the surrounding ones: where is the conversation about the plan, where is the spec, where did the retro land, who is out next week. Every space combines whichever of the 18 room types the team needs, so the Gantt chart, the chat channel, the design doc, and the standup thread are siblings in one space rather than separate products. The practical effect is fewer tabs and fewer places for the truth to fork; the plan stops being an island that has to be reconciled with reality by email every Friday.
Purpose-built rooms instead of configured sheets
In Smartsheet, everything is ultimately a sheet wearing a view, and processes like retrospectives or standups have to be improvised from rows and columns. Openbook builds each of these as a real application: the Retrospective room is live and multiplayer with voting and multiple formats; the Check-in room ships 36 templates with mood tracking and Team Pulse analytics; the Q&A room has tags, votes, and accepted answers; the Proofing room does pixel-pinned annotation on creative work; the Whiteboard is a shared multiplayer canvas. Purpose-built beats improvised: teams actually run their rituals when the tool already knows the shape of the ritual instead of asking them to build it.
Communication is built in, not bolted on
Smartsheet's native conversation surface is the row comment, which works for asking whether a task is done and little else. Openbook ships a full Chat room type with channels, DMs, and presence, plus a floating chat widget available on every page, so a question about a card gets asked next to the card. The Feed room adds posts, polls, announcements, and kudos; Townhall rooms run company-wide events with draft, live, and ended states and guest access; Event rooms handle RSVPs. Teams running Smartsheet almost always pay for Slack or Teams beside it. Teams running Openbook get the communication layer inside the same product and the same bill.
An AI agent that ships work
Openbook's AI agent is an actor, not an autocomplete. It connects to GitHub and GitLab, writes user stories onto boards, runs builds, ships and deploys changes, asks clarifying questions in card comments, and attaches spike docs and images to stories. Workflow actions and integrations reach Slack, Google Calendar, Cal.com, Calendly, Shopify, Stripe, Salesforce, and the major help desks including Zendesk and Intercom. You bring your own key from Anthropic, OpenAI, or DeepSeek, and paid plans include unlimited usage with no resold credits and no add-on fee. Smartsheet has been adding AI assistance too, but its features have generally been reserved for the higher-tier plans.
Knowledge has a home
A Smartsheet deployment can tell you the status of every task and still contain no explanation of why anything is the way it is. Openbook gives knowledge first-class rooms: Docs on a modern BlockNote editor for specs and meeting notes, Wiki rooms for reference material a team maintains over time, and Q&A rooms where answers carry tags, votes, and acceptance, so the same question stops being asked every quarter. Command-K search spans rooms of every type, so the answer, the card, and the conversation surface together in one query. The alternative in a Smartsheet shop is a separate docs product, which means another silo to buy, govern, and reconcile.
Pricing without add-on arithmetic
Openbook's pricing fits in a sentence: free forever for up to 10 members and 3 spaces with all 18 room types; Pro at $15 per user per month, or $12 with annual billing; Business at $29, or $23 annually, adding SSO, an audit log, API access, and an org-level shared AI key with usage reporting. Guests and viewers are always free and never count as seats, billing is exact-seat with no bundle increments, and every new workspace starts with a 14-day Pro trial without a credit card. Smartsheet's list prices look comparable until the premium add-ons that hold much of its real power enter the quote, at which point the math changes.

Choose Openbook if…
- Teams that want the plan and everything around it, chat, docs, retros, check-ins, and PTO tracking, in one workspace instead of Smartsheet plus three communication and knowledge tools.
- Software teams that want an AI agent wired into GitHub or GitLab, writing stories onto boards, running builds, and shipping changes on a bring-your-own-key basis with no add-on fee.
- Teams whose rituals matter: purpose-built retrospectives, async standups with mood tracking, Q&A with accepted answers, and pixel-pinned creative proofing, rather than processes improvised from rows and columns.
- Companies that want exact-seat pricing with always-free guests and viewers, and a free plan that includes every one of the 18 room types for small teams.
Stick with Smartsheet if…
- PMOs and operations teams whose work is genuinely spreadsheet-shaped: cross-sheet formulas, cell linking, dependency-driven schedules, and portfolio roll-ups computed across hundreds of project sheets.
- Organizations that need enterprise portfolio tooling, blueprint-driven project provisioning, filtered external views, and organization-wide resource management, and can budget for the premium add-ons that provide it.
- Process-heavy teams that run intake and approvals through forms and deep no-code automation, where Smartsheet's workflow engine is the core of the value rather than a nice-to-have.
- Enterprises where Smartsheet is already approved, deployed, and trained across departments, and the cost of introducing a new vendor outweighs the gains from consolidating tools.
The verdict
If your organization's work is genuinely spreadsheet-shaped, portfolios computed from hundreds of project sheets, intake processes automated through forms and approval chains, schedules driven by dependency math, Smartsheet is the stronger tool, and the premium add-ons exist because enterprises find them worth paying for. Openbook does not pretend to match that engine, and a PMO running blueprint-provisioned programs through Control Center should stay put. Smartsheet earned its place in the enterprise, and two decades of refinement show in exactly the places power users look first.
Most teams are not that PMO. They keep task lists with owners and dates in an engine built for far more, then pay separately for chat, docs, standups, and creative review. For them Openbook inverts the deal: a somewhat simpler table and timeline, in exchange for the entire workspace around it, 18 room types, built-in communication, purpose-built rituals, an AI agent that ships code, and exact-seat pricing with free guests and viewers. If the formula engine is your daily tool, keep Smartsheet. If it is scaffolding around a task list, Openbook replaces the scaffolding and the three other tools standing beside it.
FAQ
Common questions
Can Openbook replace Smartsheet?+
For many teams, yes; for some, honestly no. Openbook's Table Board room with roughly 78 templates, plus Kanban with sprints, Gantt, and Dashboard rooms, covers the project tracking most teams actually do, and adds the chat, docs, and rituals Smartsheet never had. What it does not replicate is Smartsheet's calculation engine: cross-sheet formulas, cell linking, and portfolio roll-ups computed across many sheets. If your deployment leans on those, or on premium add-ons like Control Center, Smartsheet is doing work Openbook will not do, and you should stay. If your sheets are mostly task lists with dates and owners, you are paying for an engine you do not use.
Does Openbook have formulas like Smartsheet?+
No, and this is worth being plain about. Openbook's Table Board is a structured board with typed columns and templates, built for tracking work, not a spreadsheet engine. It does not offer cross-sheet formulas, cell linking, or calculated roll-ups across boards. Teams that live on those capabilities, financial modeling inside project sheets or portfolio metrics computed from dozens of sources, should weigh that gap seriously; it may be decisive. The counter-question is what share of your team touches formulas at all. In many Smartsheet accounts a handful of builders use the engine while everyone else updates status fields, and those people need the workspace far more than the spreadsheet.
How does pricing compare?+
Openbook: free forever with all 18 room types for up to 10 members and 3 spaces; Pro at $15 per user per month, or $12 with annual billing; Business at $29, or $23 annually, with SSO, audit log, API access, and an org-level shared AI key with usage reporting. Guests and viewers are always free and never count as seats, and billing is exact-seat with no bundle increments. Smartsheet's per-user list prices are in a broadly similar range, but much of its enterprise power, portfolio provisioning, filtered external sharing, and data pipelines, ships as separately priced premium add-ons, so real-world quotes vary widely. Compare total quotes, not sticker prices, and count the communication tools you would keep paying for beside it.
Does Openbook do Gantt charts and timelines?+
Yes. Gantt is one of the 18 room types, so a project can keep a timeline view alongside its Kanban board, table board, and dashboard in the same space, and switching between them is switching rooms, not exporting data. Smartsheet's scheduling engine is deeper: predecessors, dependency recalculation, and critical-path style planning are its home turf, and a program manager running a construction schedule will notice the difference and should. For the common case, a product or marketing team that needs to see workstreams on a timeline and adjust dates as reality intervenes, Openbook's Gantt room covers the need without the spreadsheet ceremony wrapped around it.
Where do conversations happen in each tool?+
In Smartsheet, conversation lives in row comments and update requests, and anything richer moves to email, Slack, or Teams, which means the reasoning behind decisions leaves the tool. In Openbook, the Chat room provides channels, DMs, and presence, with a floating chat widget on every page, so discussion happens beside the work it concerns. The Feed room carries announcements, polls, and kudos; Townhall rooms handle company-wide events with guest access; Q&A rooms keep answered questions permanently findable. One practical consequence: when someone asks why a deadline moved, the answer is inside the workspace, one command-K search away, not buried in a chat archive in a different product.
What about Smartsheet's AI compared to Openbook's?+
Smartsheet has been adding AI assistance, formula help, text generation, and analysis, but has generally reserved it for its higher-tier plans. Openbook's AI is a different kind of thing: an agent that connects to GitHub and GitLab, writes user stories onto boards, runs builds, ships and deploys changes, asks clarifying questions in card comments, and attaches spike docs and images to stories, with workflow actions reaching Slack, Google Calendar, Cal.com, Calendly, Stripe, Salesforce, Shopify, and the major help desks. The commercial model differs too: you bring your own key from Anthropic, OpenAI, or DeepSeek, with unlimited usage on paid plans, no resold credits, and no AI add-on fee at any tier.
How hard is it to move from Smartsheet to Openbook?+
Treat it as re-homing work, not copying sheets. Most Smartsheet deployments contain a few genuinely active sheets and a long tail of dormant ones, so start by moving the active projects: a table board template or one of the 12 one-click space templates gives each team seeded rooms in minutes, and the 14-day Pro trial means you can pilot with real work before paying anything. Formula-heavy sheets deserve scrutiny on their own merits; some of them belong in an actual spreadsheet rather than in any work platform. The pieces with no Smartsheet equivalent, chat, docs, check-ins, and retros, need no migration at all, because today they live in other tools or nowhere.
Is there a free plan or trial?+
Both. The free plan is free forever, includes all 18 room types, and supports up to 10 members and 3 spaces, which is enough for a small team to run on indefinitely. Every new workspace also begins with a 14-day Pro trial, no credit card required. Guests and viewers are free on every plan and never count as seats, which matters when clients or executives only need to view dashboards or approve proofs; broad sharing never becomes a licensing question. A reasonable evaluation: provision a space from a template, move one live project in, run one retrospective and a week of check-ins with the team, and then decide with real evidence.
