A consolation build is possible, but the paid product's decisive value sits outside a solo rebuild. For Strava, log user-entered activities and map imported GPX files without recreating Strava's network. The hard boundary is athlete social graph, segment leaderboard, route data, device integrations, and scale, plus hardware data, content, coaching, and trust.
the project pack4 files · fastest path to a working personal build
You are building a lean indie version of Strava. Create the following project files first, then implement the application by following them. Keep the files updated as decisions change. Do not collapse this into a single README or prompt. ===== README.md ===== # Strava indie build ## Goal Build the smallest trustworthy replacement for the core Strava workflow for one developer or a tiny team. ## Scope Log user-entered activities, map imported GPX files, plan moderate routines, and show trends without recreating a social network or enforcing restrictive goals. ## Quick start 1. Install the documented dependencies. 2. Copy `.env.example` to `.env`. 3. Run the development command chosen during implementation. 4. Complete the acceptance checks in `BUILD_PLAN.md`. ## Honest limits This build deliberately does not replace: - athlete social graph, segment leaderboard, route data, device integrations, and scale - wearable hardware data - coach network - clinical validation - large content library and social network If those capabilities are essential, use wger instead of pretending the gap is solved. ===== AGENTS.md ===== # Agent instructions - Optimize for a working, understandable weekend build. - Prefer the fewest moving parts that satisfy the brief. - Do not invent cryptography, security guarantees, APIs, or compliance claims. - Keep secrets out of source control and logs. - Add focused tests for destructive, security-sensitive, and data-loss paths. - Run the project checks before declaring the build complete. - Record any deliberate shortcut in the README under "Tradeoffs". ===== BUILD_PLAN.md ===== # Build plan ## Original build brief Build a closest honest personal substitute for Strava in an empty repository. Use React Native with Expo, TypeScript, SQLite, and HealthKit or Health Connect only when explicitly enabled; do not offer alternative stacks. The core loop is: log user-entered activities, map imported GPX files, plan moderate routines, and show trends without recreating a social network or enforcing restrictive goals. Make the first run work locally with one documented command. Store all user data locally by default and make export straightforward. Put secrets in .env, ship .env.example, and never commit credentials. Create optional logs for activity, sleep, mood, energy, and personal notes with editable units. Let the user build moderate routines and rest days without weight-loss targets, punishment, or competitive pressure. Request health-platform permissions per data type and work fully without granting them. Show weekly patterns and consistency with neutral language and no diagnostic or body-image judgments. Add reminders that can be muted, data export, account-free local use, and full deletion. Include a clear statement that the app is not medical care and should not replace qualified advice. Include clear empty, loading, success, and recoverable error states. Add input validation, safe filenames, and graceful handling of unavailable APIs. Write focused tests for the core transformation and one end-to-end happy path. Create a README with setup, architecture, permissions, data location, and backup steps. Do not add accounts, billing, telemetry, analytics, or a hosted control plane. Do not claim to reproduce proprietary data, network liquidity, regulated access, or frontier infrastructure. Deliberately leave out medical diagnosis or treatment. Deliberately leave out extreme exercise or restrictive-eating coaching. Deliberately leave out wearable hardware, human coaching, and a large social network. Finish by running the tests and listing the exact commands used. ## Required capabilities - iOS or Android device - optional HealthKit or Health Connect permission - local storage ## Delivery order 1. Scaffold the smallest runnable application and document its commands. 2. Implement the primary data model and core workflow. 3. Add validation, safe failure states, and persistence. 4. Cover the critical path with automated tests. 5. Exercise a clean install from the README and fix every missing step. ## Done when - A new user can go from clone to first successful workflow using only the README. - The core workflow works without paid infrastructure unless the brief requires it. - Tests cover the highest-risk behavior. - Known limitations are explicit rather than hidden. ===== .env.example ===== # Copy to .env and document every variable when it is introduced. # Never put real credentials in this file. APP_ENV=development # Add only values required by the selected implementation.

People still pay for Strava because people pay for polished mobile capture, trusted content, hardware integration, and coaching rather than the basic logbook. The recurring cost buys sensor permissions, data quality, notifications, safety language, accessibility, sync, privacy, content review, and support, not just the visible interface.

Not really. Strava's value is not the code: Recheck price before merge. See the honest breakdown above.
How much does Strava cost?
Strava costs about $11.99/month (Subscription, checked 2026-07-31), which is $143.88 per year.
What do I lose by replacing Strava?
Honestly: athlete social graph, segment leaderboard, route data, device integrations, and scale; wearable hardware data; coach network; clinical validation; large content library and social network. If any of those are load-bearing for you, keep paying.
Is there an open-source alternative to Strava?
Yes: Endurain (A private Strava-shaped box for GPX, TCX and FIT files; the social network stays deleted.) FitTrackee (Import activities, map them and keep the stats on your own server.) RUNALYZE (Upload activities and get serious maps and charts for free; the social feed has been deliberately misplaced.) All 3 curated free alternatives are at vibecodeit.com/strava/alternatives. The prompt is for when you want it exactly your way.
