FirstRep
Keep paying — FirstRep's value relies on a trainer marketplace and a proprietary exercise/video library that are costly to reproduce, so self-building is not practical for a single developer.

No open-source build does this yet
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
- Generate programs with an LLM from an exercise library, assign programs to clients, track check-ins and compliance, and accept bookings/payments.
What it still won’t have
- Trainer marketplace leads and built-in client discovery
- Proprietary exercise library with 1,734 exercise entries and video demos
- The vendor's integrated AI Growth / marketing agent
- Built-in payments, payouts and Stripe-managed flows
- Mobile app and polished UX
What remains hard
- Proprietary data
1,734 exercises with video demos
- Marketplace liquidity
Your profile goes live on the FirstRep marketplace the moment you sign up.

Runnable build prompt
Build a minimal self-hosted trainer coaching app using React (frontend), Node.js + Express (API), Postgres (data), Redis (job queue), and OpenAI (LLM) for program generation. Core features in scope: (1) authenticated trainer and client accounts, (2) exercise catalog import (CSV) and a simple UI to browse exercises, (3) an LLM-backed endpoint that accepts plain-English prompts and returns a generated workout (exercises, sets, reps, rest), (4) assign workout to a client and record completion/check-ins, (5) Google Calendar booking integration and webhook-based reminders, (6) email notifications via SendGrid, (7) basic nutrition macro calculator and weekly meal-plan export. Out of scope: marketplace, video hosting, mobile apps, payment payout flows. Include error handling, input validation, background jobs for reminders and check-in aggregation, a small test suite (unit tests for API routes and integration tests for the LLM prompt flow), and Docker Compose for local dev and deployment.

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.
