Head-to-head
Vapi vs Windsurf.
Side-by-side on ratings, pricing, pros, cons, and the honest take on which to pick. Cross-category comparison: Vapi is a voice ai agent and Windsurf is a coding agent.
| Vapi | Windsurf | |
|---|---|---|
| Rating | 4.0 / 5 | 4.5 / 5 |
| Category | Voice AI Agent | Coding Agent |
| Tech level | developer | developer |
| Open source | No | No |
| Pricing | Pay-per-minute: ~$0.05–0.08 per minute, slightly cheaper than Retell at scale. Free tier for evaluation. Volume discounts. | Free tier (limited). Pro ~$15/month. Teams ~$30/user/month. |
| Best for | Engineering teams building production voice products who need fine control over the model, voice synthesis provider, and call routing. Strong API and webhook story. | Developers who want the fastest IDE-native coding agent — strong on autocomplete speed, large codebase understanding, and autonomous multi-file refactors without leaving the editor. |
| Not for | Non-technical teams — Retell's SDK is more accessible. Teams that don't need the customisation depth Vapi offers. | Teams wanting terminal-first or headless agent workflows. Windsurf is IDE-bound — Claude Code or Aider are better for CLI-driven automation. |
Our verdict on Vapi
Developer-first voice infrastructure with strong customisation hooks. Best for teams wanting more pipeline control than Retell, without building from scratch.
