Cursor for your API

About Cursor for your API

Cursor for your API is a browser-based OpenAPI editor that brings generation, editing, linting, documentation preview, and request testing into a single interface. It leverages AI-assisted edits (always showing a diff before you accept changes) and provides design, developer-experience, security, and AI-readiness insights while keeping processing local to the browser for better privacy.

Review

The tool fills a common gap: many teams edit specs in one place, validate in another, and test in yet another. By consolidating those steps and offering in-browser AI assistance with optional use of your own model key, Cursor for your API reduces context switching and addresses privacy concerns that come with uploading specs to external services.

Key Features

• Generate or import OpenAPI specs and edit them with AI-driven suggestions (diff presented before acceptance).
• Integrated linting, documentation preview, and the ability to run API calls from the same tab.
• Insights covering API design, developer experience (DX), security checks, and AI-readiness metrics.
• Privacy-first approach: all processing runs in the browser, no server-side storage of specs or keys by default; you can bring your own API key and model choice.
• One-click MCP export to make APIs agent-consumable and a pathway for agent-compatible integrations.

Pricing and Value

Cursor for your API is available for free with no sign-up required in its initial release. The core value is time saved and reduced tool fragmentation: teams can move from idea to a tested API more quickly by keeping generation, editing, linting, and testing in one place. The privacy model-local processing and optional personal keys-adds value for security-sensitive projects that avoid sending internal specs to external servers. Future improvements noted include a desktop app, deeper MCP testing, and optional repo connections for change tracking.

Pros

• Consolidates multiple API authoring and validation tasks into a single interface, cutting down on context switching.
• Runs in the browser with no default server-side storage, which helps protect sensitive specs and keys.
• AI edits are presented with diffs, so human reviewers keep final control over changes.
• Built-in linting, docs preview, and request testing support practical iteration and quick feedback.
• Free to use without sign-up for the current version, making it easy to trial.

Cons

• This is an initial release: persistent cloud saving, collaboration features, and broader API ecosystem support are still forthcoming.
• AI-assisted generation can speed work but still requires human review for nuanced or complex API behavior-especially with deeply nested or atypical schemas.
• Some advanced testing and CI/CD integrations are not yet available in the browser-only workflow.

Overall, Cursor for your API is a practical choice for API developers, technical writers, and small teams who want a privacy-conscious, all-in-one editor for OpenAPI specs and quick testing. It works well for prototyping, documenting, and iterating on APIs locally; teams that need collaborative cloud storage or full enterprise CI/CD integration may want to wait for upcoming features or combine it with existing toolchains.
