## Features
Voleeo runs natively on your machine — no browser CORS limits, no payload caps, no 30-second timeouts.
Zero telemetry, no account, no cloud lock-in: your workspaces and secrets live on disk and stay there.

### ⚡ Every protocol, one window
- Send requests over HTTP/HTTPS, gRPC, WebSocket, and GraphQL — one app, one UI.
- Import collections/workspaces from OpenAPI, Swagger, Postman, Insomnia, Bruno or Yaak.
- Inspect each request with a phase-by-phase timeline (DNS, redirects, chunks, errors) and in-flight cancellation.
- Stream and window 20 MB+ responses, filter with JSONPath, fold, and search them server-side.
### 🤖 Built for AI agents
- Voleeo is an [MCP](https://modelcontextprotocol.io) server — point any MCP client at it and your agent shares the workspace you see on screen.
- Agents read, create, and edit requests, run calls, and manage environments without leaving the chat.
### 🔐 Stay secure
- Authenticate with OAuth 2.0, Bearer, Basic, AWS SigV4, Digest, or NTLM.
- Encrypt sensitive values per workspace with AES-256-GCM.
- Store keys in your OS keychain, outside the synced workspace.
### 🔀 Organize & collaborate
- Group requests into workspaces and nested folders.
- Switch between dev, staging, and prod with global, personal, and folder-scoped variables.
- Version collections in Git — commit, push/pull, branch, and resolve conflicts, with per-file history and revert.
### 🛠️ Extend & customize
- Insert dynamic values like `{{ uuid.v4() }}` or timestamps with template functions, rendered as chips.
- Chain values from earlier responses into the next request.
- Pick from built-in base16 themes or build your own.
- Write plugins that add themes, template functions, and request actions.
