Spanna in your browser. Connect to any internet-reachable MongoDB.
Full-CRUD MongoDB client, in a tab. Free with a Spanna account, runs on any modern browser, connects to MongoDB anywhere on the public internet — Atlas, self-hosted with a public endpoint, anywhere a TLS connection can reach.
The web client reaches MongoDB through our proxy, so it can connect to any host the proxy can dial — Atlas, self-hosted with a public endpoint, or behind a bastion via SSH tunnel + inline x.509 certs. For DBs with no public route at all (localhost, VPN-only), use the desktop app.

A real MongoDB client, in a tab
Not a hosted-only data explorer. Not Atlas-locked. The web client connects to any MongoDB you can reach from the internet, including self-hosted clusters.
zero install
Open a tab, query MongoDB
Free, signed-in account, no download, no Gatekeeper, no `brew install`. Bookmark client.spanna.app and you're done.
any device
Mac, Windows, Linux, ChromeOS
If it runs a modern browser, it runs Spanna. Same Vault, same connections, same workflows on every machine you sign in from.
same product
Identical to the desktop
Documents, schema, aggregation builder, indexes, query bar. Pro features (saved queries, set diff, schema insights, cross-connection copy) gate the same way they do on desktop.
❯ spanna --diff free pro --on web
What changes between Free and Pro on the web?
The web client is fully functional on Free — connect to any MongoDB, browse, query, edit. Pro lifts the limits and unlocks the depth tools.
Free
100-doc pages · 5 saved / 2 active connections
# Fair-use rate cap on the proxy: ~60 queries/min per user. Plenty for interactive work; deliberately tight enough to keep the proxy fair for everyone. No per-day cap today; if we add one it'll show up here.
Pro
1000-doc pages · unlimited connections · saved queries · cross-conn copy · index advisor + what-if · set diff · schema insights
# Higher rate cap (~600 queries/min per user). Built for dashboards, autocomplete fan-out, multi-connection workflows.
