Productivity PWAs: Office, Notes and Collaboration Tools

What does the Productivity category cover?

The Productivity category on pwa.directory groups installable web apps built for office work, note-taking and team collaboration — the kind of task that traditionally meant opening a native desktop suite or a heavyweight web app tied to one vendor's account system. Two entries anchor the category at opposite ends of the same problem: ONLYOFFICE DocSpace, built around Microsoft-format document fidelity, and CryptPad, built around end-to-end encrypted collaboration. Both are free, both install directly from a browser, and both sit under the Productivity hub alongside the rest of the catalogue's office and collaboration tools.

According to MDN's definition, a progressive web app can be installed on a device and can operate while offline, but these are separate capabilities: installability means the app can be added to a home screen or app list from the browser, while offline support means it keeps working without a network connection. Both DocSpace and CryptPad are installable, but neither is marked offline-capable in this directory's data — both need a live connection to load, edit and sync documents, which matters if you're evaluating them as a replacement for a desktop office suite you can open on a plane.

What is ONLYOFFICE DocSpace, and how does it compare to Notion or Google Docs?

ONLYOFFICE DocSpace is described in the catalogue as an open-source office suite with pixel-perfect DOCX, XLSX and PPTX compatibility, deployable self-hosted or in the cloud. Its own page, live as of September 2026, titles itself 'ONLYOFFICE DocSpace, customizable rooms for any business purpose' and its meta description frames the product around improving 'document collaboration with offices, customers, and partners.' That framing matters for a functional comparison against Notion or Google Docs: DocSpace's pitch isn't a blank-canvas workspace but a document-fidelity tool, aimed at teams who exchange Word, Excel and PowerPoint files with people outside their own organization and need those files to open correctly on the other end.

The catalogue's description backs that positioning up with a concrete claim: formulas, macros and track-changes survive a round trip through Office, which is where most alternatives break — a detail that separates DocSpace from lighter web editors that only handle plain text well. The live page also describes a room-based structure for organizing collaboration: Collaboration rooms for real-time co-editing with comments, chat and version history; Meeting rooms for documents shared during a call; Public rooms for external readers who don't need a DocSpace account; and Virtual data rooms, Custom rooms and Form filling rooms for narrower workflows. The page also promotes working 'faster using AI agents and assistants.'

Does CryptPad work offline, and who is it for?

CryptPad is marked free, installable and not offline-capable in this directory's data. There's no separate CryptPad mobile or Android app: the catalogue notes that cryptpad.fr installs directly from Chrome or Safari as a progressive web app on both Android and iOS, so 'installing' means adding the site to the home screen rather than downloading anything from Google Play or the App Store. The trade-off for skipping offline support is what happens once you are online: CryptPad's own site states that JavaScript must be enabled to perform encryption in the browser, and the catalogue describes an architecture where keys are derived client-side and the server only ever stores ciphertext.

The catalogue lists specific audiences this suits: encrypted meeting notes between lawyers and clients, GDPR-strict EU teams replacing Google Workspace, classroom collaboration where students don't have accounts, fast secure brainstorming sessions where a Whiteboard URL gets dropped into a messaging app, and local government or healthcare projects that require EU data residency. It also notes CryptPad is hosted in France and used by some ministerial workgroups. The toolset covers a rich-text Pad, a CSV-compatible Sheet, Kanban, Code with syntax highlighting, Slide, Whiteboard and Forms — enough to replace daily office use, though not every advanced feature of a desktop suite.

The same source is explicit about limits: CryptPad is not built for heavy spreadsheet users who need real Excel formula compatibility, since Sheet covers basics rather than power-user pivot tables, and it lacks comment threads with @mentions and approvals that Google Docs offers. Performance on documents over roughly fifty pages can stutter on older devices because encryption and decryption happen in the browser. Free-tier storage on cryptpad.fr is capped at 1GB; heavier use means self-hosting the server, which the catalogue says is well-documented via Docker, or paying for a managed instance.

How much do DocSpace and CryptPad cost?

ONLYOFFICE DocSpace's own page states it is 'FREE for users and guests, pay for admins only' — meaning the collaboration surface, including rooms, editing and guest access, costs nothing, while payment applies to the admin seats that manage a workspace. CryptPad is also free to use, with a 1GB storage cap on the hosted cryptpad.fr instance according to the catalogue's limitations note, and it doesn't require an account for guest use of a shared document. Both suites list an open path beyond their free tier: DocSpace can be self-hosted instead of run in the cloud, and CryptPad can be self-hosted via a documented Docker setup, or used through a paid managed instance for more storage.

The free/paid split lines up with what each product optimizes for. DocSpace's admin-pays model fits an organization onboarding a whole team, where a handful of admins configure rooms and permissions for many free guest collaborators. CryptPad's storage-based cap fits looser, ad hoc collaboration — a lawyer sharing encrypted notes with one client, or a class working on a single document — where the friction point is disk space rather than seat count.

Which tool fits which use case?

DocSpace is the stronger fit when the job is document fidelity: exchanging Word, Excel and PowerPoint files with clients, contractors or partners who use Microsoft Office, and needing formulas, macros and track-changes to survive that round trip intact. Its room structure — Meeting rooms tied to calls, Public rooms for external readers without an account, Virtual data rooms for sensitive exchanges — suits an organization that regularly brings outside collaborators into a shared workspace without handing them full account access. Because it's open-source and self-hostable, it also fits teams that want to keep documents on their own infrastructure rather than a vendor's cloud.

CryptPad is the stronger fit when the priority is confidentiality over format perfection. The catalogue's use-case list names encrypted meeting notes between lawyers and clients, GDPR-strict EU teams moving off Google Workspace, classroom collaboration without accounts, and government or healthcare projects that require EU data residency — cases where who can read a document matters more than whether a client's spreadsheet formulas render identically. Its no-account, share-a-link workflow also suits one-off collaboration: dropping a Whiteboard link into a chat for a quick brainstorm, rather than provisioning a workspace for a single session.

Is there a decent offline alternative to Notion in this category?

Readers searching for a Notion offline alternative won't find true offline support in either flagship app here: both ONLYOFFICE DocSpace and CryptPad are marked installable but not offline-capable, so a lost connection stops editing in both. What they offer instead is something Notion doesn't: DocSpace gives genuine Microsoft-format fidelity for documents shared outside a team, and CryptPad gives end-to-end encryption with no account requirement, which covers a rich-text Pad, Kanban board and other note-adjacent formats even if it can't work offline on a plane. For a workspace built specifically for note-taking, the dedicated note-taking-pwas roundup is the closer match.

That said, CryptPad's Whiteboard tool overlaps with quick visual note capture, and its no-account link-sharing means a note can go from idea to shared draft faster than setting up a Notion workspace, even without offline access. Readers comparing whiteboard-style tools specifically should see the dedicated whiteboard-pwas list rather than this category page, since that comparison covers the drawing-first tools this page doesn't retread.
