Lyftr Review
A Go + React self-hosted fitness tracker with workout logging, programs, gym mode, nutrition tracking, and an 800+ exercise library.
Each review covers deployability, value versus commercial alternatives, and privacy model. Tools that can run locally were started and exercised; mobile or backend-dependent tools were assessed from published builds, source code, and deploy guides. Ratings reflect what we were able to verify.
Lyftr — Self-Hosted Workout and Nutrition Tracker
A Go + React self-hosted fitness tracker with workout logging, programs, gym mode, nutrition tracking, and an 800+ exercise library. Last updated: 2026-06-21.
One-sentence verdict: The most polished self-hosted fitness tracker in this batch — a credible open-source alternative to Hevy or Strong for users comfortable with Docker.
What the System Is
Lyftr is a self-hosted workout and nutrition tracker. It is built as:
- Go (Gin) backend with JWT authentication and refresh tokens.
- React + TypeScript + Tailwind CSS + Vite frontend.
- SQLite database stored in a single file.
- 800+ exercise library auto-synced from free-exercise-db on first run.
- Docker Compose deployment with pre-built images.
Features include workout logging, reusable program templates, active workout mode, gym mode, exercise detail with personal records and progression charts, a dashboard with volume trends and consistency heatmap, weight tracking, and nutrition tracking with calories, macros, food search, and barcode scan.

How to Install and Deploy
The deploy guide uses Docker Compose with pre-built images.
cd /data2/docker/going-global/repos/lyftr
cp .env.example .env
# Set a strong JWT secret and avoid port conflicts
sed -i 's/^JWT_SECRET=.*/JWT_SECRET=lyftr-super-secret-32-char-long-key-123456/' .env
sed -i 's/^PORT=.*/PORT=8082/' .env
sed -i 's|^CORS_ORIGIN=.*|CORS_ORIGIN=http://localhost:8082|' .env
docker compose up -d
The backend seeds the exercise library asynchronously in the background. Open http://localhost:8082 and create an account.
How to Test
The documented test flow is:
- Open
http://localhost:8082. - Click Create account and register, or use the demo credentials
demo@lyftr.local/LyftrPass123!if seeded. - Explore the Home dashboard: Volume Trend, Consistency, Nutrition, Weight.
- Start a workout, browse the 800+ exercise library, and log sets.
- Check the Programs and Gym Mode views.
- Verify that data persists after logging out and back in.
Privacy & Compliance
Lyftr is self-hosted; all data stays in the local SQLite file (./data/lyftr.db). It is not HIPAA compliant and is intended for personal fitness tracking, not clinical use. Backup is a single-file copy.
Lyftr vs Commercial Fitness Trackers
| Dimension | Lyftr | Commercial Tracker (e.g., Hevy, Strong, Freeletics) |
|---|---|---|
| Cost | Free / self-hosted | Subscription |
| Data location | Your server | Vendor cloud |
| Exercise library | 800+ auto-synced | Large, often larger |
| Mobile apps | Browser/PWA (native iOS planned) | Native iOS / Android |
| Social features | Not listed | Often included |
| Setup effort | Medium: Docker, JWT secret, port config | Low: app store install |
| Open source | Yes | No |
Who Should Use It
- Self-hosters who want a modern workout and nutrition tracker.
- Users looking to own their fitness data instead of storing it in a commercial cloud.
- Raspberry Pi or VPS owners who want a lightweight fitness app.
Who Shouldn't Use It
- People who need polished native mobile apps today.
- Users who rely on wearable auto-sync or Apple Health / Google Fit integration (planned but not available).
- Anyone needing clinical-grade nutrition or exercise guidance.
FAQ
Does Lyftr require a database server?
No. It uses a single SQLite file stored in ./data/lyftr.db. No PostgreSQL or MySQL setup is required.
How does the exercise library get populated?
On first startup Lyftr automatically fetches 800+ exercises from free-exercise-db in the background. Existing workout data is not overwritten on re-sync.
Can I import data from Hevy or Strong?
Strong / Hevy CSV import is on the roadmap but not yet available.
Verdict
Lyftr is the most complete self-hosted fitness tracker in this batch. It combines a clean modern UI, a large exercise library, workout logging, and nutrition tracking in a simple Docker-based package. For users willing to self-host, it is a genuine alternative to subscription fitness apps.
