Blobster od Hein Dauven

Blobster is a local-first structured data workbench for developers.

Open JSON, YAML, TOML, XML, CSV, TSV, NDJSON/JSONL, Markdown, .env files, JWTs, HAR files and OpenAPI specs directly in your browser. Use it to inspect API responses, config files, exports, tokens, logs and other developer data without pasting sensitive content into public formatter websites.

Features:
- Open files, paste text, drag and drop files, or open URLs
- Auto-open high-confidence raw structured pages
- View data as tree, table, raw text, Markdown preview, HAR explorer or OpenAPI explorer
- Search keys and values
- Edit supported data locally
- Copy values, rows, paths, subtrees, and redacted output
- Decode JWTs locally
- Redact likely secrets before copying
- Use the sidebar for local inspection beside the current page

Blobster has no account, backend, telemetry, analytics, cloud sync or public paste URLs. Documents are processed locally in your browser.
