Codeium
Codeium was a free AI code completion tool that became Windsurf, was acquired by Cognition, and now ships as Devin Desktop. The Codeium brand is retired — this page explains the chain and what existing users should do.
- The original free individual tier was genuinely generous for its time
- Plugin coverage reached editors most AI vendors ignored
- Development continued rather than shutting down — the product still ships
- Redirects are in place, so old links still reach the current product
- The Codeium brand is retired, so its documentation is effectively orphaned
- Two renames in two years make search results contradictory and unreliable
- Terms that attracted original users may not have survived the ownership change
Replit AI
Replit AI turns a written description into a working application — the Agent writes the code, and Replit supplies the database, authentication, hosting, and monitoring, so a prototype goes live without a local setup or a deployment pipeline.
- Removes the entire setup chain — no local environment, database, or host to configure
- Genuinely lets non-developers ship working internal tools
- Live URL from the first build, so feedback starts immediately
- Unusually wide output range for an AI builder
- Agent reliability drops sharply as an application grows interconnected
- Effort-based billing makes cost hard to forecast before you start
- Design control is coarse and output looks recognisably generated
