Project and task management decision
Rise Calendar
A capable developer can build a limited self-hosted replacement for Rise’s core calendar+task+basic scheduling features, but reproducing the polished cross-platform client experience, long-term sync reliability, and mature scheduling analytics would require substantially more time and engineering effort.

Nothing published replaces this one, so a replacement starts from an empty file. Here is what it would have to cover.
What a replacement has to do
- Users create tasks/projects; tasks with dates appear on personal calendars; events and tasks can be scheduled/reshuffled; team calendars sync with Google/Outlook; scheduling links let external users book time.
What it still won’t have
- Polished cross-platform desktop and native mobile apps (iOS/Android) and platform-specific integrations
- Years of reliability fixes and edge-case calendar sync robustness
- The product’s proprietary scheduling/optimization refinements and historical analytics
- Polished UX, keyboard-first commands, and dozens of small quality-of-life features
What remains hard
- Product polish and ongoing maintenance
First-year cost
No published price
Rise Calendar does not publish a price we could read, so there is nothing to compare against. What building costs is below.

Runnable build prompt
Build a self-hosted calendar+task web app using: Next.js (React) frontend, Postgres for data, Node.js/Express backend, and an optional Redis for jobs. Implement: 1) OAuth calendar sync with Google Calendar and Microsoft Graph (read/write + webhooks), 2) tasks/projects CRUD with assignment and due-dates stored in Postgres, 3) mapping of tasks to calendar events and bi-directional sync logic, 4) scheduling links endpoint that finds availability and creates events, 5) a simple FocusGuard that automatically creates protected focus events when a user’s scheduled focus falls below a threshold, 6) combined calendar+task UI (day/week/month) and a 'My Focus' view, 7) CSV export of tasks/projects. Out of scope: native iOS/Android apps, advanced automatic rescheduling across teams, and long-running analytics pipelines. Include error handling for API failures and rate limits, tests for sync logic and scheduling endpoints, and a README with deployment steps (Docker + docker-compose).
How we checked
How the score was reached
- Partly verdict base52
- 2 cited sources+1
- 3/3 assessment runs agreed+4
- Evidence score57
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.
