AI security & agent safety — what's accelerating
Short edition by design — this field is young and most of the serious tooling is still closed-source or internal. But the open-source pattern is clear: the work that is accelerating is about containment. Give an autonomous agent less blast radius, and assume it will be compromised.
Top mover
A lightweight OpenClaw alternative whose entire pitch is that it runs each agent inside a container for isolation, then connects out to WhatsApp, Telegram, Slack, Discord and Gmail. The velocity says the market wants connected agents that are still sandboxed by default — convenience without handing an LLM your whole machine.

Secure execution
Secure, elastic infrastructure for running AI-generated code. This is the grown-up version of the same instinct: never execute model output on your own host — spin up a disposable sandbox, run it there, throw it away. Mature, well-starred, and the de-facto open answer for code-execution safety.

Honest footnote — not a tool
A large, long-running resource collection on ethical hacking and security — tagged ai-security but it is a reading list, not agent-safety tooling. Genuinely useful as a reference; it does not belong in the same category as the two repos above, and its velocity (8/day on a 9-year-old repo) reflects that it is a library, not a moving project.

The whole edition is two real repos and a bookshelf. That is the honest state of open-source AI security right now: containment and sandboxing are accelerating, while prompt-injection defense, agent auditing, and red-teaming tooling remain mostly behind closed doors. Worth re-checking this bucket monthly — it should fill out fast.

How this was made
Live GitHub pull, bucketed by inference/local-runtime keywords, each repo verified not-archived and pushed within 45 days, ranked by stars/day, then curated for substance. Star counts pulled at publish — they move daily; re-verify before reposting.
