.http file validator
Check a .http or .rest file against the syntax Karve actually runs. Find malformed requests, unresolved variables, duplicate names, and likely committed secrets without uploading your file.
Drop a .http or .rest file here or browse — or paste below.
Validates automatically — nothing leaves your browser. Formatting only normalizes line endings, so request bodies remain untouched.
Validated output
Validated output will appear here.
Syntax checked
- GET, POST, PUT, PATCH, DELETE, HEAD, and OPTIONS
- ### request blocks and duplicate names
- @name declarations and {{name}} references
- Header syntax and body separation
- Likely literal secrets in variables and sensitive headers
Environment-aware warnings
An unresolved variable is a warning, not an error: Karve may resolve it from your active local .env environment. File-level @variables take precedence.
