About Manifest
Manifest is a browser workspace platform. Save, switch, and share Spaces—intentional setups that bundle tabs, layouts, themes, notes, and focus rules. Use the web app for discovery & sync and the extension for tab & window powers.
Introduction
With Manifest you can create shareable Spaces—complete browser work environments for Deep Work, Debugging, Research, or Play. Each Space can include a theme, a layout hint, a set of tabs/links, optional notes, and rules (like focus or URL limits).
Save the state you want (tabs, layout hints, notes, rules) to a Spacefile (JSON) and restore it in one click.
Attach a visual theme per Space to match intention—calm, cozy, neon, mono.
Publish Spaces to the gallery or import from a link/Gist. One click to install.
Quick start (≈ 5 minutes)
- Install the Manifest extension from the Chrome Web Store.
- Open the web app and create your first Space (name, theme, starter tabs).
- Save the Space and use Switch to enter it instantly.
- (Optional) Enable Sync to use your Spaces across devices.
- (Optional) Share a Space: publish to the gallery or copy a share link.
Core concepts
Spaces
The atomic unit in Manifest. A declarative workspace describing tabs/links, layout hints, theme, notes, and rules. Spaces can be saved, switched, exported (JSON), and shared.
Spacefile
The JSON specification that defines a Space (e.g., deep-work.mspace.json
). Store it locally,
sync it encrypted (optional), publish to the gallery, or host it in a Gist for one-click import.
Themes
Visual appearance per Space (colors, typography accents, backgrounds). Themes make context changes visible and memorable.
Rules (Focus & Limits)
Optional constraints per Space: domain allow/deny lists, tab quotas, timeboxing. Implemented via the extension (e.g., Declarative Net Request) for privacy-first blocking.
Sync
Keep Spaces consistent across devices. Local-first by default; enable sync in settings to store encrypted copies server-side.
Plugins & Panels
Optional modules inside a Space (Notes, Bookmarks, To-Do, Window Manager, Documentation). Panels can be bundled in shared Spaces.
Gallery & Import
Browse community Spaces, preview, and import in one click. Advanced users can host a Spacefile in a Gist and link it to the viewer/importer.
Plans & Subscriptions
Manifest starts free with a limited number of Spaces and basic features. Pro unlocks unlimited Spaces, sync, advanced rules, a theme editor, and early access to plugins. Payments are handled by trusted providers (e.g., Stripe); we never store full card details.
- Free: essentials for getting started and importing from the gallery.
- Pro: unlimited Spaces, cross-device sync, rules/quotas, theme editor.
- Teams (optional): shared Spaces, org templates, role-based access.
Permissions & Privacy
The extension requests only the permissions required to power features like tab/window management and focus rules. By default, your data stays local; sync is opt-in. See our Privacy Policy and Terms of Use.
