termalData · database client
A database client in the same app as your servers.
Open a database like any other host — a schema tree, a SQL editor and a structure view for 13 engines. Reach a public database directly, or one behind a firewall through a Connector — no exposed port, no tunnel to wire by hand. In the desktop app and right in the browser. And an AI agent can query it too, read-only by default.

01 / one client, thirteen engines
Relational, document, key-value — all in one place.
Most database tools cover the SQL databases and stop. Termalin speaks thirteen engines across every shape of store, so the terminal you already keep open is also the client for the database next to it.
02 / behind a firewall, one click
Reach a private database without a tunnel wizard.
A production database usually isn't on the public internet — so with other clients you first stand up an SSH tunnel by hand, then point the tool at localhost. Termalin does it for you: connect directly to a public host, or through a Connector — a one-line agent on a box in that private network. No inbound port to open, no SSH key to hand out, and the database never faces the internet. On the desktop you can also forward through an existing SSH host you already have.
03 / see it without typing SQL
Browse the whole server, then query.
Expand a connection and see every database, table and view — with approximate row counts — then a table's columns, indexes, foreign keys and grants, all without writing a query. When you do want SQL, the editor runs a statement or just the selection with Ctrl+Enter, and results land in a grid beside a Structure tab.
- ▸A live schema tree: databases → tables → columns.
- ▸Structure at a glance — types, keys, indexes and who's granted access.
- ▸The right query language per engine — SQL, Mongo filters, Redis commands, Cypher and more.
04 / in your browser too
Query a database from any device — no install.
Sign in at termal.in/account and the database client runs right in the browser — the same schema tree, editor and grid, on a laptop or a phone. A database behind a firewall stays reachable through the Connector, and the credential is decrypted in your browser and kept only for that session — the server never stores it. Most database clients are a desktop app and nothing else. More on the web cabinet →
05 / safe for agents
Let an agent read your database — not your password.
Termalin's built-in MCP server gives an AI agent data_list, data_tables, data_schema and data_query — so Claude or ChatGPT can explore your schema and answer questions about your data. It's read-only by default and per-connection, gated by your consent, and every query lands in the audit log. Ask an agent "what's the schema of the orders table?" or "how many signups yesterday?" without handing it write access — or the credential. How to give an agent safe DB access →
06 / one app, not five
Beside your terminals, files and keys.
Your database connections live in the same encrypted vault as your SSH hosts, keys, snippets and S3 buckets — one master password, one end-to-end encrypted sync, one recycle bin. Jump from a shell on a box to the database running on it without a second tool, a second login, or a second place your credentials live. All features →
Questions
Which databases does Termalin support?
Thirteen engines: PostgreSQL, MySQL/MariaDB, SQLite, SQL Server, MongoDB (and DocumentDB), Redis, ClickHouse, Elasticsearch/OpenSearch, Cassandra/ScyllaDB, Neo4j, InfluxDB, RabbitMQ and Cloudflare D1 — relational, document, key-value, columnar, search, graph, time-series, wide-column and message-broker stores in one client.
Can it connect to a database behind a firewall?
Yes. Point it at a public host:port directly, or reach a private database through the keyless Termalin Connector — a one-line agent on a machine in that network, with no inbound port to open and no SSH key to hand out. On the desktop you can also tunnel through an existing SSH host. The database itself never faces the internet. How security works →
Does the database client work in the browser?
Yes — sign in at termal.in/account and browse and query your databases from any device, including a private one reached through a Connector. The credential is decrypted in your browser and used only for that session; the server never stores it.
Can an AI agent query my database safely?
Yes — the MCP server exposes data_list, data_tables, data_schema and data_query, read-only by default and per-connection, so an agent can answer questions about your data without write access or the password. More on the MCP server →
Is the database client free?
Yes — it's part of the free desktop app. Paid plans add the cloud: reach and query databases from the browser cabinet on any device, with your connections synced end-to-end encrypted. New accounts get Pro free for 14 days, no card. See pricing →
Can I edit data and create tables?
You can run any statement in the SQL editor today — SELECT, INSERT, UPDATE, CREATE TABLE, ALTER — and see rows affected. A point-and-click editor (edit a cell inline, add rows, create tables from a dialog) is rolling out on top of that.
Your databases, in the app you already keep open.
Thirteen engines, a schema tree and a SQL editor — reachable directly or through a Connector, in the desktop app and the browser. Free to start; new accounts get Pro free for 14 days.
