Convex vs Val Town
Side-by-side comparison of features, pricing, ratings, and alternatives.
Convex provides a fully managed backend platform that includes a reactive, versioned database, serverless functions, and file storage. It syncs data in real time across web and mobile clients, eliminating the need for custom server infrastructure. Developers can write TypeScript functions that run automatically on data changes, query the database with a simple API, and leverage built‑in authentication and scaling. The platform is designed for rapid iteration and production‑grade reliability.
Val Town is a hosted TypeScript platform that lets developers, GTM teams, and ops folks write a small script (a "val") in a browser-based editor and have it running live on the internet almost instantly, without configuring servers, build pipelines, or deploy steps. Vals can run as HTTP endpoints, scheduled cron jobs, or email handlers, and each one gets built-in SQLite storage and S3-compatible blob storage. The platform includes an AI coding assistant (Townie) for generating and iterating on vals, native MCP server support so tools like Claude and Cursor can call or create vals directly, and a CLI for working locally while still deploying to Val Town's hosted runtime. It's positioned as a fast way to turn a webhook, internal automation, or one-off integration into a permanent, shareable URL.
- Zero‑ops backend infrastructure
- Realtime data propagation
- Strong TypeScript integration
- Automatic scaling and pay‑as‑you‑go pricing
- Genuinely fast from code to live URL, useful for quick webhooks and automations
- Built-in storage removes a lot of typical setup friction
- Deep integration with AI coding tools via MCP
- Generous free tier for personal or small projects
- Limited to JavaScript/TypeScript runtimes
- Vendor lock‑in to Convex cloud
- Advanced query patterns may require workarounds
- Wall-clock execution time limits make it unsuitable for long-running jobs
- Pricing scales quickly once you need team accounts or higher run volume
- Less mature ecosystem than established serverless platforms

The Verdict
AI-generated from listing dataVal Town excels at ultra‑fast, single‑script deployments with built‑in storage, while Convex offers a richer realtime backend and scaling for full‑stack apps.
Key differences
- •Val Town provides instant (≈100 ms) live URLs for individual TypeScript scripts; Convex runs functions on data changes with realtime sync.
- •Val Town includes built‑in SQLite and S3‑compatible blob storage per script; Convex offers a versioned reactive database and CDN‑backed file storage.
- •Val Town’s AI‑assistant integration (MCP, Claude, Cursor) is a core feature; Convex focuses on automatic scaling and authentication policies.
- •Val Town limits execution time, making it unsuitable for long‑running jobs; Convex has no such wall‑clock limits and handles traffic spikes automatically.
- •Convex is open source and has broader integration ecosystem (Vercel, Netlify, React, Next.js); Val Town is closed‑source with fewer integrations.

Common questions
Can I run long‑running background jobs?
Val Town has wall‑clock execution limits, making it unsuitable; Convex has no such limits.
Is there a free tier for small projects?
Both offer freemium plans; Val Town’s free tier is generous for personal scripts, while Convex’s free tier covers limited backend usage.
How easy is it to move my code to another provider?
Val Town provides a CLI and API for exporting vals; Convex is open source but tightly coupled to its platform, implying higher lock‑in.
