Prelight Data Sandboxes

Vibe-code Data Pipelines Safely and Unlock Agentic Data Engineering.

Isolate, test, and validate AI-generated pipeline changes before they ever touch production. Data Sandboxes give your agents and engineers a safe space to iterate confidently.

Everything You Need to Ship Data Pipelines Safely

Isolated Sandbox Environments

Spin up isolated copies of your data environment in seconds. Test pipeline changes without any risk to production data or downstream consumers.

Automated Data Quality Checks

Run automated data quality checks and tests at dev-time. Catch schema drift, nulls, outliers, and logic errors before code is promoted.

Human-in-the-Loop Review

Built-in data review workflows let your team approve or reject pipeline changes before promotion. Keep humans in control of what goes to production.

One-Click Rollback

Something went wrong? Turnkey rollback gets you back to a known-good state instantly — no manual intervention required.

Agentic Workflow Integration

Tightly integrated with Claude, Gemini, Codex, and other coding agents. Let your AI write the pipeline, let Prelight make sure it’s safe.

Free and Open Source

Prelight is free and open-source. Get started today on GitHub — no license required.

Why Data is Different

One mistake can nuke your entire database.

Vibe-coding apps is forgiving — a bad push ships a broken UI, you fix it and redeploy. The blast radius is bounded.

Vibe-coding data is not forgiving. It's very easy for an agent to inadvertently run:

DELETE FROM orders

No WHERE clause. No warning. Records gone — potentially millions of them, across tables that may have no backup. By the time you notice, the damage has already propagated downstream.

This isn't hypothetical — it's already happening in production. Prelight gives agents a sandbox that is correct by construction — so they can iterate freely without the risk of an irrecoverable mistake.

There’s a massive, massive opportunity for “vibecode safely in prod at scale”

1B+ developers who look like JER, don’t read 100% of their prompts, and want to build are coming online

For us toolmakers, the burden of making bulletproof tooling goes up

We live in exciting times

An AI Agent Just Destroyed Our Production Data. It Confessed in Writing.
A 30-hour timeline of how Cursor's agent, Railway's API, and an industry that markets AI safety faster than it ships it took down a small business serving rental companies across the country.

Ship data pipelines safely, from day one.

Give your agents and engineers a safe space to iterate — with automated checks, human review, and one-click rollback.
