Paste code or upload multiple files. Stellar uses reasoning AI to return ranked vulnerabilities, affected lines, and concrete patch suggestions in seconds.
Platform
From a single pasted snippet to a fleet of microservices — Stellar reasons about the attack surface the way your best engineer would, just faster.
Fast triage on snippets and configs — get findings in seconds.
Multi-step analysis for complex flows, smart contracts, and architectural review.
Upload several files together — Stellar reasons across them, not just one at a time.
We don't retain your source code after the scan completes.
Severity-ordered results with affected lines and concrete patch suggestions.
Every scan is saved to your workspace so you can revisit findings later.
How it works
Drop in a snippet, log file, or wire up the CLI to your CI. Stellar accepts any text payload.
The engine traces dataflow, simulates attacker paths, and cross-references known CVEs.
Get ranked findings with line numbers, exploit vectors, and copy-pasteable fixes.
Our promise
Paste code, get a real security review in seconds — backed by reasoning models, not regex. No accounts harvested, no source code stored.
