Free-tier AI coding IDE, formerly Codeium and Windsurf
Originally Codeium's free AI code-completion tool, rebranded to Windsurf in 2025, then acquired by Cognition (maker of Devin) in late 2025 and rebranded again to Devin Desktop in June 2026. Still ships a genuinely free tier alongside paid plans.

The 8 coding agents we track, listed alphabetically. 4 of the 8 publish a free tier. Prices are the vendor’s own published starting figure and change without notice — check the vendor’s pricing page before committing.
The bar under a price compares that plan with the dearest monthly plan in this table (5 of the 8 rows are flat monthly prices). Custom, per-seat, per-usage and annual prices are not on the same scale, so they carry no bar — a missing bar does not mean cheaper.
