OpenAPI Studio

Purpose: OpenAPI Studio is a visual editor for designing, testing, and publishing AI-ready APIs.
Flow builder: The visual flow builder represents API paths as a node graph and supports four layout algorithms.
Endpoint execution: A server-side proxy runs API requests and avoids browser CORS limitations.
Recipes: Recipes chain up to 10 API calls, map responses with JSONPath, and apply per-step assertions.
MCP server: Each workspace includes a six-tool MCP server with search, get, create, update, run, and analyze tools.
Integrations: Native integrations include GitHub, Slack, Linear, Notion, and MCP connections for AI assistants.
Integration security: Supported integrations use OAuth and store tokens encrypted in the workspace; raw API keys are not requested.
Data privacy: The service says it does not sell data, use client-side analytics, or use tracking pixels, and allows export or deletion of data.
Data hosting: Cloud data is stored on Cloudflare D1, KV, and R2, while self-hosted deployments use the customer's Cloudflare account.
Access control: Workspaces provide Owner, Editor, and Viewer roles with enforced role-based permissions.
Security limitations: SSO, SCIM, and audit logs are not yet offered.
WebSocket support: WebSocket endpoints can be modeled and tested alongside HTTP and exported as AsyncAPI 3.0 YAML.
Support: Community support is provided through GitHub Issues on all tiers, while priority email support is available on Pro, Team, and Scale.
Maker: OpenAPI Studio is described as a solo developer project built in the open with a public codebase and transparent roadmap.
Price from: $9/mo
