Project and task management decision
RescueTime
A technical user can reproduce the core automatic-tracking + reporting and Focus sessions, but they won't match RescueTime's years of collected data, cross-platform polish, and breadth of integrations without substantial additional time and resources.

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
- Run a lightweight background agent that records active window titles and URLs, send events to a server that aggregates and categorizes activity, show per-user reports and dashboards, and allow users to set goals/receive alerts and start Focus sessions which block specified domains/apps.
What it still won’t have
- Years of historical activity data and derived baselines
- Polished cross-platform agent stability and browser extension coverage
- Broad third-party integrations and enterprise billing/invoice options
- Brand recognition and large existing user community
What remains hard
- Proprietary data

Runnable build prompt
Build a minimal RescueTime-like service: use an Electron (or native) background agent to capture active window titles and URLs and send batched events to a Node.js + Express API; store events and users in Postgres; implement categorization rules in the backend, a React web UI for timeline/reports/goals, and a small admin job that produces weekly summary emails. In scope: agent event capture (Windows/macOS), backend ingestion and categorization, user auth, dashboard with timeline and productivity report, Focus session push to agent (simple blocking by domain/process), and weekly summary emails. Out of scope: mobile SDKs, enterprise SSO, payments, and advanced integrations. Include robust error handling, tests for ingestion and categorization, and deployment scripts for a single small VPS (Docker).

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.
