Open-source security and code review tooling for AI-written code

AI writes code faster than teams can review it, and a measurable share of that code ships with exploitable flaws. These projects close the gap: scanners, review gates and analysis that run before a merge rather than after an incident.

The security problem with generated code is not that models are careless — it is that review capacity did not scale with generation speed. A reviewer who used to read forty lines a day now approves four hundred, and approval quality falls exactly where you would predict.

The tooling below moves checks to where the volume is: pre-merge, automated, and specific enough to be worth reading. Each entry states what class of problem it catches, because a scanner that flags everything gets muted within a week and then it protects nothing.

Questions people ask

Does AI-generated code need different security tooling than hand-written code?
The vulnerability classes are the same; the distribution is not. Generated code repeats a small set of mistakes at scale — outdated patterns, missing validation, invented dependencies — so tools tuned for those catch more per unit of noise.
What is a hallucinated dependency and why does it matter?
A model imports a package that does not exist. It matters because attackers publish packages under exactly those names, so a typo-tolerant install turns an invented import into a supply-chain compromise. Verifying that every dependency resolves to something real is a cheap check with a large payoff.
Where in the workflow should these run?
Pre-merge, and fast. A scan that takes twenty minutes gets skipped under deadline; one that takes twenty seconds becomes part of how the team works.
