The free alternative to Windsurf
A free agentic IDE experience, without the $15/mo seat.
In short
- Freebuff is a free alternative to Windsurf with the same agentic, multi-file autonomy.
- Windsurf Pro is $15/mo (and rising on enterprise). Freebuff is $0.
- You get 9 specialized subagents and the freedom to switch models per task.
- Editor-agnostic — works in VS Code, JetBrains, Vim, or a bare terminal.
Windsurf’s Cascade made multi-file autonomous edits feel safe. Freebuff has the same cadence — plan, edit, run, verify — without the seat license.
