RexaDB

Modern database studio for teams who ship.

RexaDB is a modern desktop database studio for PostgreSQL, MySQL, SQLite, MongoDB, and more. Visualize schemas, write SQL, browse data, and let AI handle the heavy lifting — all from one fast, keyboard-friendly app.

Supports 100+ databases through JDBC — PostgreSQL, MySQL, SQLite, MongoDB, Redis, MariaDB, ClickHouse, SQL Server, Supabase, Neon, Turso, PlanetScale, Timescale, and more. Sign in with your provider and your databases appear instantly, no saved connections needed.

Key Features

• Fast data browsing — Virtualized grid that handles millions of rows, with filtering and record inspection
• Lightning queries — Multi-tab SQL editor (Monaco) with split-view results, autocomplete, formatting, EXPLAIN / profiling, and export to CSV, JSON, or Markdown
• Schema visualization — Interactive ER diagrams with real-time updates, relationship explorer, and schema documentation
• AI Agent — Generate complex queries, understand schemas, and get results without switching context (Anthropic, Google, OpenAI, and more)
• Workflow Automation — Scheduled jobs, chained actions, and one-click runtimes
• Safe by design — Read-only mode, transaction safeguards, and connection encryption. Your data never leaves your machine.
• Team-ready — Team workspaces, shared connections, role-based access, SSO, query version control, audit logging
• Cross-platform — Desktop builds for macOS (arm64 / Intel), Windows, and Linux

Downloads

Download RexaDB free (no credit card required):

• Website: https://www.rexadb.app/download
• All builds: GitHub Releases

Getting Started (Development)

# install dependencies
npm install
run web app
npm run dev
run desktop app (Tauri)
npm run tauri:dev

Install with Nix (NixOS / nix)

RexaDB ships a Nix flake (flake.nix, nix/) with a reproducible dev shell, per-component packages, the desktop app, and NixOS / Home Manager modules (Linux-first; macOS gets nix develop + headless packages).

# full toolchain: bun, node, rust, cargo-tauri, JDK 21, WebKitGTK deps
nix develop
build pieces
nix build .#frontend        # Next.js static export
nix build .#rexadb-server   # compiled sidecar server
nix build .#rexadb-oracle-bridge
nix build .#java-bridge     # bridge.jar + minimal JRE
desktop app (Linux) — run it, or install via the HM module
nix build .#rexadb
nix run .                   # launch RexaDB
nix run .#server            # sidecar only (REXADB_SERVER_PORT=3867)
optional: install into your profile
nix profile install .#rexadb

Tagged releases push prebuilt x86_64-linux binaries to the rexadb Cachix cache (see nixConfig in flake.nix), so nix run / nix profile install download instead of compiling on that platform — no setup needed on your end. Other systems (aarch64-linux, macOS) still build from source. If you see a trust warning about the cache key, update your flake input to the latest release tag.

If Nix prints ignoring untrusted substituter 'https://rexadb.cachix.org', you are not a trusted user and starts compiling anyway, your daemon runs multi-user (default on NixOS / Determinate / macOS installs): it discards cache settings that come from flakes. Register the cache in the system config instead — this trusts exactly this cache and grants nothing else:

# Linux (NixOS: set nix.settings.extra-substituters /
nix.settings.extra-trusted-public-keys declaratively instead)
printf '%s\n' \
  'extra-substituters = https://rexadb.cachix.org' \
  'extra-trusted-public-keys = rexadb.cachix.org-1:pVrB+j93ten7xXFzxhAdQ2m/Eco2yiwfBT0Wk5QgYww=' \
  | sudo tee -a /etc/nix/nix.conf
sudo systemctl restart nix-daemon
macOS
printf '%s\n' \
  'extra-substituters = https://rexadb.cachix.org' \
  'extra-trusted-public-keys = rexadb.cachix.org-1:pVrB+j93ten7xXFzxhAdQ2m/Eco2yiwfBT0Wk5QgYww=' \
  | sudo tee -a /etc/nix/nix.conf
sudo launchctl kickstart -k system/org.nixos.nix-daemon

Alternative: add yourself to trusted-users (root $USER in the same file). That also fixes every other flake-provided cache at once, but it is much broader — a trusted user may configure any substituter and use other restricted settings — so prefer the scoped lines above unless you know you want that. Single-user Nix installs are unaffected (every user is trusted).

NixOS module (flake input inputs.rexadb.url = "github:RexaDB/RexaDB"):

services.rexadb = {
  enable = true;
  package = inputs.rexadb.packages.${pkgs.system}.rexadb-server;
};

Home Manager:

programs.rexadb = {
  enable = true;
  package = inputs.rexadb.packages.${pkgs.system}.rexadb;
};

Notes:

• flake.lock is committed for reproducible builds; run nix flake update

• .envrc (use flake, for direnv users) is covered by the repo's

• packages.rexadb is Linux-only (webkitgtk_4_1 / Tauri bundling).

• Like the other release builds, the Nix frontend build does not bake in

• Supabase config is baked at build time (NEXT_PUBLIC_*): the Nix

• The Nix desktop build ships with the Tauri auto-updater disabled (it

• Portable .deb / AppImage installers come from the normal release
