Never run a query against the wrong database again.

Zentro is a Project-centric SQL IDE — every project knows its environment and asks before anything irreversible.

  • One project per service — isolated workspaces, zero context-switching
  • Always know which environment you're in — Dev, Staging, or Prod
  • Safety guardrails that activate before every production action

What you get

Safety, speed, and clarity — in one IDE.

1.

Always know which environment you're in.

Zentro is built around projects — one workspace per service, one context per environment. The moment you open a connection, you know exactly where you are. Before you write to production, the app asks you.

Easy to switch environments — with a visible overlay

A persistent badge shows Dev, Staging, or Production at a glance, so you always know which database you're connected to before you run a query.

Open multiple projects at once — one window per project

Keep Production and Staging running in separate windows instead of juggling tabs, so a copy-paste mistake can't land in the wrong environment.

Confirm steps and audit reason before production writes

Pro

Sensitive writes to production require a typed confirmation and a reason, leaving a lightweight audit trail without slowing you down.

Snapshot and rollback — recover from mistakes fast

Pro

Every write is backed by an automatic snapshot, so a bad query is a rollback away instead of a support ticket.

2.

A fast editor for everyday queries.

Tabs, autocomplete, export, history, and saved scripts — everything you reach for during a normal database session.

Multi-tab editor

Open as many query tabs as you need across connections and jump between them without losing your place.

Async execution with cancel

Long-running queries execute in the background — cancel safely at any time without locking up the editor.

Schema-aware autocomplete

Autocomplete understands your tables, columns, and types, so you write correct SQL faster.

3.

See the schema clearly.

Browse tables, inspect structure, and understand relationships without switching tools.

Table definitions, columns, and constraints

Inspect column types, defaults, and foreign key constraints without leaving the app.

Table data browsing

Browse and edit table data directly, even across millions of rows.

Interactive ERD

Visualize how your tables relate with an interactive, crow's-foot notation entity relationship diagram.

Why I built Zentro

We've all run a
DELETE on the wrong database

Most SQL tools give you a list of connections. You pick one, run your query, and hope you remembered which one was staging and which was production. After one too many close calls — and one that wasn't close at all — I wanted something that made the environment impossible to ignore.

The idea behind Zentro is simple: your database work belongs inside a project, not in a flat list of connections. Each project knows exactly which environment it's targeting, shows it clearly, and asks before you do anything irreversible. It's the safety layer that should have always been there.

Zentro is built by a solo developer who uses it every day. The free tier exists because good tooling shouldn't require a budget approval. Pro exists for the moments that need an extra layer of trust when shipping to production.

How Zentro is different

Built for engineers who ship to production not just explore data.

Other SQL tools manage connections. Zentro manages context — the project, the environment, and what's safe to run.
