npm install -g vesperWhen you ask Vesper Code to make changes, it coordinates specialized agents that work together — not a single model doing everything.
Scans your codebase to find relevant files and understand the architecture.
Plans which files need changes and in what order.
Makes precise, context-aware edits across multiple files.
Validates changes for correctness and consistency.

A full agent platform with battle-tested tooling.
Specialized agents work together — File Picker, Planner, Editor, and Reviewer — giving you better context understanding and fewer errors than single-model tools.
Not locked into one provider. Use Claude, GPT, DeepSeek, Qwen, and more. Bring your own API keys or let us handle it — switch models for different tasks instantly.
TypeScript generators let you mix AI generation with programmatic control. Agents can spawn sub-agents, branch on conditions, and run multi-step processes.
Build Vesper Code into your applications. Create custom tools, integrate with CI/CD, or embed coding assistance into your products.
Compose existing published agents to get a leg up. Reuse battle-tested workflows created by the community instead of starting from scratch.
File operations, code search, terminal commands, web search, and more. Every tool the agent needs to understand and edit your project.
Benchmarked across 175+ real coding tasks on popular open-source projects.
Works with any stack. One-command setup. Zero friction.
