RedLens

A Redshift-native SQL IDE for VS Code, with an MCP server built in.

Connect four ways, browse your catalog, run SQL, read plans with warehouse-aware warnings — and hand the same connections to Copilot or Claude without wiring up a thing.

Open core, said plainly

The free extension is open source under the MIT licence and it is the whole free product — not a demo, not a time limit. Its source is at redlens-io/redlens.

RedLens Pro is a separate paid extension that adds cost and performance advice, the Redshift console, AI grounded in your schema, and governance administration. It is $99 per person, per year — buy it here, or see what is in it. Every Pro feature is unlocked for a 14-day trial that starts on first activation and asks for no card and no sign-up.

Three commitments, and the third is the one that costs us something:

• The free tier is complete. Connecting, browsing, editing, running, reading results and the embedded MCP server. No cap on connections, ever.
• Every safety feature is free — read-only mode, the production safeguard, transaction control and PII-safe masking. Charging for not leaking PII is not a position worth defending.
• Nothing that ships free ever moves to Pro. New Pro features are new features, never features you already had.

Where the line falls is a file you can read before installing anything: src/licensing/tiers.ts.

Your data does not leave your machine

RedLens has no server. Your SQL, your results, your schemas, your credentials and your AWS traffic go directly between your machine and your own systems. We do not proxy, store or receive any of it. Licence keys are verified offline, against a public key inside the extension.

See Privacy for what that means precisely, including the one thing that is optional and off by default.
