What makes blob different

Real apps. Any AI tool. No credits. No lock-in.

No credits. No limits.

Your AI writes the code, blob hosts it. No generation credits, no token caps, no artificial limits. Pay for hosting, not for building.

Bolt.new, Lovable & Base44 charge credits per generation. Run out = stop building.

Any AI tool. No lock-in.

Use Claude Code, Cursor, Windsurf, or any MCP-compatible AI. You pick the best tool for the job. Switch anytime.

App builders lock you into their built-in AI. Switch tools = start over.

Real backends, not just UIs

Databases, auth, cron jobs, API routes, webhooks — full server-side code. App builders can only generate frontends.

Bolt.new & Lovable build landing pages. blob hosts the entire stack.

AI safety net, built in

Secret scanning, health checks, auto-rollback, error diagnosis. Your AI writes fast — blob catches what it gets wrong.

App builders have no deploy safety. Developer platforms trust the code blindly.
