About Windsurf

Windsurf is an AI-native IDE that integrates advanced AI assistance directly into the code editing experience. The editor features an Agent Editor for managing fleets of local and cloud agents, enabling autonomous code writing, testing, and shipping. It provides a full IDE with syntax highlighting, autocomplete, and debugging tools, and supports multi-model and multi-agent orchestration via the Agent Client Protocol (ACP). Windsurf allows developers to delegate tasks to agents while staying in control, with capabilities such as automated pull requests, session management, and real-time collaboration. The free tier offers a light quota for coding with agents, while paid plans increase quotas and provide access to frontier models like OpenAI, Claude, and Gemini.

FAQ

How does usage work?
Each paid plan comes with a usage allowance that refreshes automatically on a daily and weekly basis. Cost per message varies based on the model used, the task size and complexity, and the reasoning required.
What happens when I reach my usage limit?
Most users will never hit their limits. If you do go beyond your included usage on a paid plan, you can purchase extra usage which is consumed at API pricing.
How can I make my usage limits last longer?
Control the size of your prompts, be precise with instructions, remove unnecessary context, and switch to smaller models (e.g., Haiku, GPT 5.2 Mini, open-source models like Kimi K2.5) for routine tasks.
What is included in the Free plan?
The Free plan includes a light quota to code with agents, limited model availability, unlimited inline edits, and unlimited Tab completions.
