The verdict: can you vibe code Strava?
Build a personal single-user subset that imports GPX files and displays maps and stats, but skip the global segment engine and social network.
Strava is a massive fitness social network built on 17 years of engineering. While you can prompt an AI agent to build a Next.js app that parses a GPX file and draws a map with Mapbox, replicating the segment matching math, hardware webhook synchronization across Garmin/Wahoo, and the high-frequency spatial database queries makes this a serious multi-week undertaking. For personal use, paying for Strava is vastly more practical than attempting to code a full clone.
Estimated effort: 4-6 weeks of part-time work
What you can't replicate
- The global social graph of 195 million active athletes
- Billions of crowdsourced segment attempts and leaderboards
- Direct API and hardware partnerships with major watch manufacturers

What Strava does
A social fitness network and tracking platform used by runners, cyclists, and walkers to record activities, analyze performance metrics, and share workouts through an activity feed.
Core features
- Manual activity upload (GPX/FIT file parsing) and GPS coordinate rendering
- Interactive activity map with elevation and pace charts using Mapbox
- Performance metrics calculation (speed, pace, elevation, heart rate)
- Social activity feed with posts, kudos, and comments
- Location-based segment matching engine
- User profiles, follow graphs, and personal stats dashboard

The hard parts of vibe coding Strava
- Parsing and ingesting thousands of high-frequency spatial and telemetry points per workout from raw GPX/FIT files
- Building a segment matching engine that compares noisy user GPS traces against polyline coordinate sets at scale
- Rendering smooth, performant interactive maps and custom elevation profiles for large datasets
- Designing a distributed social feed and notification architecture for concurrent activity sharing

Build guide
01Project Scaffolding & Database Schema
Initialize the Next.js project with Tailwind CSS, shadcn/ui, and configure Neon Postgres with Prisma or Drizzle ORM.
Create a new Next.js project configured with TypeScript, Tailwind CSS, and App Router. Set up Drizzle ORM connecting to Neon Postgres. Define database schemas for users, activities (id, user_id, title, description, sport_type, distance, moving_time, elevation_gain, start_date, polyline), and activity_streams (storing high-frequency lat, lon, elevation, heart_rate, time arrays as JSONB or relational points). Ensure clean folder structure and strict TypeScript types.02Authentication System
Implement local authentication using better-auth to manage single-user or multi-user login securely.
Integrate better-auth into the Next.js app for email/password authentication linked to the Neon Postgres database. Create sign-in, sign-up, and account settings pages using shadcn/ui components. Protect dashboard and activity routes so unauthenticated users are redirected to login.03GPX File Ingestion & Parsing Engine
Build a robust file upload parser that ingests GPX and FIT files, extracts telemetry points, computes summary metrics, and stores spatial data.
Build an API route that accepts GPX file uploads via multipart form data. Use an XML parser library to extract track points (<trkpt> with lat, lon, ele, time), calculate total distance using the Haversine formula, compute elevation gain, total moving time, and average pace. Store the parsed summary in the activities table and save compressed polyline arrays for map display. Handle malformed files gracefully with clear error messages.04Interactive Map & Telemetry Dashboard
Create a detailed workout detail view featuring Mapbox GL JS route rendering and interactive elevation/pace charts.
Build an activity detail page in Next.js using Mapbox GL JS to render the activity route polyline on an interactive map. Below the map, implement interactive charts using Recharts showing elevation profile and pace over time, with synced hover tooltips that track cursor position across both the map and charts. Ensure responsive design for desktop and mobile browsers.05Activity Feed & Social Interactions
Develop a chronological activity feed displaying workouts, allowing users to leave comments and give kudos.
Create a social activity feed page that displays activities from the user and followed accounts in reverse chronological order. Implement database tables and API endpoints for kudos (likes) and comments on each activity. Build React components for the feed items showing static map previews, athlete avatars, metrics summary, and inline comment threads.

Vibe code Strava: FAQ
- Can you vibe code Strava yourself?
- Serious undertaking — 38/100 vibecodeable. Build a personal single-user subset that imports GPX files and displays maps and stats, but skip the global segment engine and social network.
- How long does it take to vibe code Strava?
- 4-6 weeks of part-time work — roughly 40-60 hours of hands-on time with an AI coding agent.
- How do you build your own Strava?
- Scoped to personal use: Next.js with Tailwind CSS and shadcn/ui on the front, Next.js Server Actions / API Routes with fast-xml-parser for GPX handling behind it, Neon (Serverless Postgres with PostGIS extension for spatial queries) for data. Follow the 5-step build guide on this page — each step has a paste-ready prompt for an AI coding agent.
- How do you code your own Strava without being an expert?
- Use an AI coding tool (Claude Code or Cursor) and work in small steps: scaffold, data model, core screens, then deploy. Realistic effort: 4-6 weeks of part-time work. The prompts on this page are written so the AI does the heavy lifting.
- How much does it cost to vibe code Strava instead of paying?
- About ~$20 one-time to start and $0/mo to run, versus $11.99/mo for Strava. Break-even: Never (built for learning and personal use).
- What stack should you use to vibe code Strava?
- Next.js with Tailwind CSS and shadcn/ui; Next.js Server Actions / API Routes with fast-xml-parser for GPX handling; Neon (Serverless Postgres with PostGIS extension for spatial queries); plus Mapbox GL JS for map rendering, Recharts for pace and elevation graphs.
