Replit
Browser-based IDE with Agent 4 — zero to deployed app.
About
Replit (replit.com) is the browser-based IDE plus Replit Agent — describe an app in plain language and it scaffolds, builds, and deploys it. Agent 4 (March 2026) added an infinite Design Canvas, mobile app output, and native Slack/Notion integrations.
Freemium with effort-based credits: Starter (free, daily credits, one published app), Core $20/mo, Pro $100/mo, Enterprise custom. Watch costs — heavy agent users report $50–300/mo in overages. Best for prototypes and fast iteration, not production backends.
What it can do
- Browser IDE — zero install
- Replit Agent (natural-language builds)
- One-click deployment
- Built-in Postgres + secrets
- Mobile app output
Setup
- Sign up at replit.com — nothing to install.
- Prompt the Agent with a concrete spec (data model, auth, deploy target).
- Iterate in plain language; publish when ready.
- Set budget alerts — effort-based pricing can surprise.
Prerequisites
Browser; paid plan for serious builds.
