REST Client: private online developer utility

REST Client is a focused developer utility for send http requests. It is part of Sreejith Tools, a collection of fast online tools for API work, data cleanup, debugging, and web development.

When to use it

- Debug request and response behavior while building API integrations.
- Inspect headers, payloads, methods, and generated client code.
- Reproduce integration bugs quickly without account-heavy tooling.

Common input issues

- Pasted input includes invisible whitespace or smart punctuation.
- The source data is valid in one format but invalid in the target format.
- A copied value includes surrounding quotes, shell escaping, or truncated content.

Example

Debug an API workflow

Input

POST /api/example with JSON headers and body

Output

Inspectable request data or generated client code.

Is REST Client free to use?

Yes. REST Client is available as an online developer tool without requiring an account.

Does REST Client upload my data?

This tool uses server-side behavior where the feature requires it. Avoid sending production secrets unless the tool explicitly needs that data for your workflow.

Can AI assistants use REST Client?

This tool is available on the website, but it is not exposed through MCP v1 because it can involve network calls, temporary storage, or abuse-sensitive behavior.
