Hevy Pro
A narrow, self-hosted workout tracker (logging, routines, basic social and analytics) is realistic for a competent developer to build and run, but Hevy's large community presence and polished native/watch integrations are durable advantages that are costly to reproduce.

The code exists. It is not what you are paying for.
These 2 projects are real, published, and do the core job — and this page still says keep paying. What the subscription buys is network effects and brand trust, and none of that ships in a repository. Fork one anyway if you want to. Go in knowing what it does not carry.

Runnable build prompt
Build a minimal self-hosted workout tracker using Node.js (Express), Postgres, and React (web + PWA). Implement: user auth (email/password), CRUD for workouts and routines, follow/like/comment social actions, PR and one-rep-max computations, CSV/JSON import-export, and a responsive React UI for logging workouts. Provide REST endpoints, input validation, error handling, unit tests for backend logic, and Docker Compose for local deployment. Out of scope: native iOS/Android apps, Apple Watch/WearOS integrations, video library, and large-scale multi-tenant hosting.

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.
