Local MongoDB-style workbench — CamaDB

What it does

Import JSON collections, browse documents, run supported CamaDB queries, preview edits and export JSON locally.

How to use it

1. Import JSON arrays or JSONL into up to five in-memory collections. Each accepts 5,000 documents / 2 million characters.
2. Choose a filter, pipeline or update preview. Apply previewed edits explicitly and export collections before leaving.
3. Processing stays in this browser. No sign-up or upload.

Example

The filter {"score":{"$gte":10}} matches documents with a score of at least 10.

Methodology

CamaDB 3.0.0-rc.0 runs on isolated InMemory collections in workers. Queries and edits use its public API; preview returns before/after snapshots.

Limitations

Workbenches support a documented subset of release operators, not full MongoDB compatibility. JSON depth 20, 20 pipeline stages and 30-second deadline. Identity is immutable; data is lost on reload.

Automation

This tool runs in your browser. No upload API or MCP endpoint is available.
