Project and task management decision
Akiflow
A capable engineer can build a useful, self-hosted time-blocking planner with calendar sync and a basic auto-scheduler (multi-week). Full parity with Akiflow’s integrations, polished native apps and AI assistant is larger in scope, so keeping the paid product may be justified for teams wanting the complete experience.

Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need — the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship.
What a replacement has to do
- Capture tasks from user input or integrations → store tasks and metadata → sync with calendar accounts → compute and place time-blocks (auto-schedule) → surface agenda and allow edits.
What it still won’t have
- Polish and UX of native mobile & desktop apps
- Large catalogue of native integrations and 3000+ Zapier/IFTTT connectors
- Proprietary AI workflows and assistant tuning
- Team billing, analytics, and enterprise support
What remains hard
- Brand trust

What we assumed
The verdict above measures whether you could build it. This one is only about money.
Runnable build prompt
Build a minimal self-hosted time-blocking planner web app using: React + Tailwind front end, Node.js + Express API, Postgres DB, and Redis for job queuing. Implement OAuth integrations for Google Calendar and Outlook (one account each) with two-way sync; task CRUD (title, description, duration, recurrence, tags); an auto-scheduler service that scans calendar free/busy and places time-blocks based on task durations and priorities (heuristic greedy algorithm); a calendar UI with drag-and-drop rescheduling and a quick-capture command bar (natural-language parsing using an LLM API). Out of scope: full Zapier/IFTTT ecosystem, native mobile apps, multi-user billing, and advanced proprietary AI tuning. Include error handling for failed calendar syncs, unit tests for scheduler logic, integration tests for OAuth flows, and deployment scripts (Docker + Postgres + Redis) with a basic monitoring alert (email on sync failure).

The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time — so the same evidence always produces the same number.
