wger

wger is one of the longest-running open-source fitness tracking applications, with over 6,000 GitHub stars and an active community of athletes, coaches, and developers contributing exercise descriptions, translations, and feature improvements. The platform combines workout planning, nutrition tracking, and body measurement logging in a single Django application — purpose-built for self-hosters who want full control over personal fitness data instead of trusting it to commercial fitness SaaS platforms.

Common Use Cases

Recreational athletes and gym-goers self-host wger as a personal workout tracker, logging sets, reps, and weights against structured routines while monitoring body weight and progress photos over months or years. Personal trainers and online coaches deploy wger as a multi-tenant coaching backend, giving each client a private account on infrastructure the trainer controls — eliminating per-client SaaS fees while keeping training data private. Nutrition-focused users leverage wger's calorie and macro tracking against meal logs and a searchable food database to plan and review daily intake without uploading meal photos to commercial apps. Developers and quantified-self enthusiasts use wger's comprehensive REST API to build custom dashboards in Grafana, Home Assistant, or Apple Health that pull workout history and body measurements into broader personal analytics setups. Sports clubs and gyms run wger as a member-facing exercise reference and group workout planner alongside their existing booking systems.

• Shopping list generation from planned meals and macro targets
• Comprehensive REST API and OpenAPI schema for custom dashboards and integrations
• Multi-language support with translations contributed by the community

Mobile and Integrations

wger ships with companion native apps for iOS and Android that connect to a self-hosted instance over the REST API, so athletes can log sets, reps, body weight, and meals from the gym without opening a browser. The mobile apps support offline logging with sync, exercise lookups against the local catalog, and progress charting that mirrors the web UI. The REST API itself is documented via OpenAPI and used by community-built integrations including Grafana dashboards, Home Assistant components, and Apple Health bridges. Coaches and analysts often layer their own reporting on top of the API to track client progress without manually exporting data.

Why deploy wger on Hostinger VPS

Deploying wger on a Hostinger VPS gives athletes, coaches, and quantified-self enthusiasts a private fitness platform under their own domain with no per-user fees, no third-party access to body measurements or nutrition data, and no SaaS lock-in. The dedicated CPU and RAM keep page rendering and API responses snappy even with multi-year workout histories, while persistent volume storage protects exercise databases, training logs, food entries, and progress photos across container updates and rebuilds. Self-hosting also keeps sensitive personal information — body weight, measurements, eating habits — out of cloud provider hands, which matters for both individual privacy and compliance with regulations like GDPR. Full root access lets coaches integrate wger with their own scheduling and billing tools, configure custom domains for client-facing branding, and tune PostgreSQL for the size of their roster without negotiating with a SaaS vendor.
