Ever wondered how hackers use AI? 🤖
We wrote a guide mapping the current landscape of AI-enhanced hacking.
What else should we cover? 👇: caido.io/blog/2026-03-24-ai-…

🚀 v0.56.0 is here!
This release introduces Match & Replace support within Replay and the ability to re-order collections or sessions for better organization.
👉 Download the update: caido.io/download
Our Javascript Client SDK was a pretty big hit 🔥
We have customers using it for a lot usecases like AI automation, CICD pipelines, replacing (very expensive) Burp Enterprise, etc.
Now I present the python version! 🐍

🤖 @trace37_labs shared recently how they use Caido as a core part of their autonomous hunting platform.
Paul Reed, founder of @trace37_labs, says it best:
> I wanted the proxy to think. Not in a vague “AI-powered” marketing sense, but concretely: a proxy that watches traffic in real-time and generates passive detection rules tailored to the target [...]. A proxy that refines its own detection rules based on which findings turn out to be true positives and which are noise. A proxy that bridges the gap between “I see interesting traffic” and “an AI specialist is already investigating it.”

The most common feedback of 2025: "I'll switch when there are more plugins."
We spent the year solving that.
Along with 29 new plugins (thanks to our community), we shipped:
- 10 major releases
- Hands-on Labs
- AI Integration

The first version of the Caido browser extension is out for Firefox (in-review for Chrome). Very basic for now but the goal is to add tighter browser integrations next year. Try it out: addons.mozilla.org/en-US/fir…
Friday I met with some pentest teams that told me screenshots were still a pain for them. So I made a plugin today for Caido, It handles everything: highlights, redaction, layout size, headers hiding.
Time to level up your screenshot game!
Try it out: github.com/caido-community/s…

🤝 We’re introducing a new way for teams to use Caido.
Share the same instance and continue work exactly where a teammate left off, without exporting or passing files around.
Up next: real time collaboration.
Caido v0.53.0 → caido.io/blog/2025-11-06-rel…
