Byson: MongoDB Client

Now optimized for larger screens with a 3-column workspace. Plus custom-CA TLS and X.509 client-certificate auth for secure MongoDB connections.

Byson is a fast, native MongoDB client for developers who manage databases on the go.

Connect to any MongoDB deployment - local, self-hosted, or Atlas - and browse, query, and analyze your data with a clean, mobile-first interface.

CONNECT SECURELY • Save multiple connections with TLS and SSH tunnel support • SCRAM auth and trust-on-first-use SSH host keys • Trust self-signed or private-CA servers by pasting your own CA certificate (custom CA TLS) • X.509 client-certificate authentication (MONGODB-X509), including over an SSH tunnel • RSA (rsa-sha2-256/512) and ed25519 SSH keys, with or without a passphrase - works with modern, hardened SSH servers • Paste a standard mongodb:// or mongodb+srv:// URI and go.

WORKS WITH • MongoDB 4.x, 5.x, 6.x, and 7.x • Standalone, replica set, and Atlas (mongodb+srv seed list) deployments • Local, self-hosted, and cloud-hosted databases

BROWSE YOUR DATA • Walk databases and collections with live document counts • Inspect documents with JSON syntax highlighting • Insert, edit, and delete documents safely

QUERY & AGGREGATE • Run find and aggregation pipelines with raw MongoDB commands • View results as a tree, table, or raw JSON • Save queries, keep history, and re-run with one tap • Keyset pagination for large collections

PROFILE & OPTIMIZE • Built-in profiler: docs examined vs returned, timing, and plan • COLLSCAN detection with one-tap index suggestions • Create and manage indexes (unique, sparse, TTL)

ANALYZE SCHEMA • Sample a collection to infer field paths, types, and coverage • Spot sparse fields and mixed types • Sensitive fields are redacted automatically

AI COPILOT (BRING YOUR OWN KEY) • Describe what you want in plain language and get an aggregation pipeline • Works with Anthropic, OpenAI-compatible, and Google AI Studio • Byson sends only schema structure and dummy examples - never your raw documents • Every pipeline is validated and shown for review; nothing runs automatically • Your API key is encrypted on-device and never displayed after saving

FREE & PRO Byson is free to use for everyday browsing and querying. Upgrade to Pro for unlimited saved connections, unlimited saved queries and history, the full Schema Analyzer, and unlimited AI aggregation tools.

PRIVACY FIRST Your connection strings and API keys are stored encrypted on your device. Byson has no backend that sees your data. Add an optional Face ID, Touch ID, or passcode lock for the app.
