DBHub
Get started

Self-hosted · 7 database engines · runs in your browser

One browser IDE for every database you run

Browse schemas, edit data, write SQL with schema-aware autocomplete, read execution plans and move data in and out of PostgreSQL, MySQL, MariaDB, SQLite, SQL Server, Oracle and Redis. Your credentials never reach the browser.

The DBHub SQL workspace: a schema tree, an SQL editor with a revenue query against a production MySQL database, and a 50-row result grid.

Built for daily database work

Everything you reach for, in one place

DBHub replaces a desktop client per engine with one fast web app that your whole team can use.

Data grid

Browse and edit data without writing SQL

Open any table on a fast, virtualised grid. Paging, sorting and filtering run on the server, so large tables open as quickly as small ones.

  • Inline editing with optimistic-concurrency conflict detection
  • Insert, duplicate, delete and bulk update with an SQL preview
  • Structure, indexes, foreign keys, triggers and DDL one tab away

Execution plans

See exactly why a query is slow

Run EXPLAIN or EXPLAIN ANALYZE from the editor and read the plan as a tree with real timings, row estimates and the share of time spent in each step.

  • Findings for full scans, misestimates and expensive sorts
  • Join analysis and index suggestions
  • Data-modifying statements are analysed inside a rolled-back transaction

Schema diff

Ship schema changes with confidence

Pick a source and a target, such as staging and production, and DBHub lists every added, removed and changed object, then writes the migration SQL for you.

  • Destructive changes are highlighted before you copy anything
  • Filter by change type, object type or name
  • Nothing is executed. You decide when and where to run it

Imports & exports

Move data in and out in the background

Export a table, a query or a whole database, or import a file into a table. Jobs keep running when you close the dialog or leave the page.

  • CSV, TSV, JSON, NDJSON, Excel and SQL
  • Live progress, per-row error isolation and a notification when done
  • CSV exports neutralise spreadsheet formulas

All features

Everything included, no plugins required

Each capability adapts to the engine you connect to: actions an engine does not support are hidden or disabled, with the reason shown.

  • Connections

    Seven engines from a connection string or a form. SSL/TLS with custom CAs and client certificates, SSH tunnels with host-key pinning, read-only mode and development, staging or production labels.

  • Schema explorer

    Databases, schemas, tables, views, routines and sequences, loaded on demand. Every table has an overview, structure, indexes, foreign keys, constraints, triggers and DDL.

  • Data grid

    Server-side paging, sorting, filters and search. Edit cells inline with conflict detection, then insert, duplicate, delete or bulk update with a preview of the generated SQL.

  • Table designer

    Create or alter tables, columns, indexes, foreign keys and constraints. Every change is shown as DDL before you apply it.

  • SQL editor

    Monaco with schema-aware completion for aliases, joins and columns. Format, run a statement, a selection or a script, cancel long queries, and keep your tabs when you navigate away.

  • Query safety

    Statements are classified as read, write, DDL or admin. Read-only connections, production protection and row estimates for mass UPDATE or DELETE stop accidents before they run.

  • Execution plans

    EXPLAIN and EXPLAIN ANALYZE as a visual plan tree, with findings, join analysis and index suggestions that point at the slow step.

  • Performance dashboard

    Query counts, average, P95 and P99 latency, latency categories you can tune, slow queries and the most expensive statements over time.

  • Import & export

    CSV, TSV, JSON, NDJSON, Excel and SQL. Jobs run in the background with live progress, isolate bad rows, and insert, skip or upsert on conflict.

  • History & saved queries

    Every execution is searchable with its timing and status. Save the queries you reuse and share them with your workspace.

  • Reports

    Ready-made reports on database and table size, row counts, index usage, unused indexes, slow queries and errors, exportable as CSV or JSON.

  • Schema diff

    Compare two schemas, for example staging against production, and get the migration SQL. Destructive changes are flagged and nothing runs until you decide.

  • ER diagrams

    Relationships drawn from your foreign keys and laid out automatically. Filter tables and columns, zoom, and export the diagram.

  • Redis browser

    Scan keys by pattern and type, inspect and edit values of every type, manage TTLs, and use the built-in CLI and memory view.

  • Workspaces & roles

    Share connections and queries with your team, with roles that decide what each member is allowed to do.

  • Audit log

    Sensitive actions in every workspace, such as exports, are recorded with who did what and when.

  • Guest mode

    Try DBHub without an account. Your editors, connections and history are kept in this browser only, and come back on your next visit.

  • AI assistant (optional)

    An assistant for your SQL that receives schema metadata only, never your row data. It stays off unless an administrator enables it.

Secure by design

Your data stays behind your server

DBHub is self-hosted. Queries run on the DBHub server, which checks who you are, what your role allows and whether the statement is safe before anything reaches your database.

  • Every query runs on the DBHub server. The browser never talks to your database.
  • Credentials are encrypted with AES-256-GCM and never returned by the API.
  • SSRF protection and a network policy decide which database hosts are reachable.
  • Production connections ask for confirmation before writes, DDL and mass updates.
  • Role-based permissions per workspace, rate limits and a complete audit log.
  • SSH tunnels with host-key pinning and TLS with your own certificate authority.
