Sunsama alternatives: 3 free & open-source picks
Curated, verified, and actually free. No trials, no crippled tiers. Star counts and last-activity dates checked by hand, not scraped and forgotten.
A local task planner with timeboxes, focus mode and its own stopwatch; less glossy, less interested in your wallet.

installUse the browser/PWA or install a packaged desktop or mobile build
dataTasks, projects, time records, and settings are local-first in browser or app storage; optional synchronization and backups use the user's chosen WebDAV or Dropbox account
setup✓ installs clean
the catch vs SunsamaSuper Productivity has timeboxes and focus tools but not Sunsama’s polished guided daily review, shutdown ritual, and external task aggregation.
facts verified 2026-08-10
It auto-plans unlimited tasks for the next two weeks; priorities and dependencies are how the paid plan gets you.

installCreate a hosted account in the web app or install the iOS or Android app
enginesA deterministic scheduling algorithm; FlowSavvy explicitly says it does not use machine learning to build schedules
dataTasks, events, and settings live in FlowSavvy's cloud database and synchronize with connected Google, Outlook, or iCloud calendars; the service currently provides no general calendar import or export
the catch vs SunsamaFlowSavvy schedules work automatically but lacks Sunsama’s guided daily-planning and shutdown ritual and its broad task-source import workflow.
setupRequires an internet connection; calendar synchronization requires OAuth or app-specific credentials

One calendar gets task-to-time-block planning and some AI suggestions; multiple calendars and deeper automation cost extra.
licenseproprietary, free
runstheir cloud
installCreate a hosted web account and connect one supported calendar; the web app can be installed to a home screen
enginesA private per-user deep-learning scheduling model; some language features use OpenAI, according to Trevor's documentation
dataTasks, calendar events, and scheduling state are processed and stored in Trevor's hosted infrastructure, with connected calendar data synchronized through provider APIs
the catch vs SunsamaTrevor is a lighter web scheduler with one free calendar rather than Sunsama’s deliberate daily-planning ritual and multi-source task workspace.
setupNo native desktop or mobile app; calendar integrations require OAuth, and the free tier is limited to one calendar account

Is there a free alternative to Sunsama?
Yes: Super Productivity, FlowSavvy Free, Trevor AI Free. Every tool on this page is either open source or genuinely free to use long-term: no trials, no crippled tiers.
Should I just build my own Sunsama?
Our verdict is PARCIAL. A daily planning dashboard is not hard, but Sunsama's value is many integrations, careful UX, calendar sync, and habit-forming workflow. If you'd rather build, the exact one-shot prompt is free at puedovibecodearlo.app/sunsama.
