Onboarding a contractor should not mean buying a seat forever.🫣 Caido Team licenses are reassignable: the seat that covers a contractor this month covers someone permanent next. Billing is centralized, one invoice not ten receipts.💪 Book a demo: www.caido.io/orgs/

Can you say, with certainty, where your team's testing traffic exited last week? 😉 Run Caido in your own infra. Traffic exits an egress IP you control. The team reaches one instance from any browser, and history lives in one central log.😎 Book a demo: www.caido.io/orgs/

Your AI agent tests blind.🫣 It cannot see your scopes, Match & Replace rules, or the requests already in your project. Connect it to Caido over MCP for live access to the whole project, not an isolated snippet. One setup the team shares.💪 Book a demo: www.caido.io/orgs/

AI testing in a team does not stall on capability. It stalls on control.💪 Bring your own provider and key: Anthropic, OpenAI, Google, or OpenRouter. The AI runs on an account you trust, not a black box. You pick the model and the project. Book a demo: www.caido.io/orgs/

You filter HTTP traffic in Caido with HTTPQL. WebSocket traffic didn't have an equivalent. v0.57.0 changes that. Introducing StreamQL: a Query language for filtering WebSocket messages in WS History, bringing it in line with HTTP History and Search. Download Now → www.caido.io/download

We built Caido to be API-first. Now an open source AI pentest agent drives Caido. Pentest Copilot from BugBase added support for Caido: HTTP History, Replay, Automate, OAST and more. It all runs on our official SDK, and works over MCP too. This is what API-first is for. github.com/bugbasesecur...

Running an Automate attack and then scrolling raw responses to find the one value you actually care about is a waste of time. Caido v0.57.0 adds Custom Extractors to Automate.

Testing WebSocket messages in Caido wasn't possible before v0.57.0. Now it is. 🎉 Send WS messages straight from the Replay page: - Create a new WebSocket session. - Set the initial HTTP request. - Start sending, then edit and resend frames as you go. Download Now → www.caido.io/download

Caido v0.57.0 is out. 🎉 The headliners: - WebSocket in Replay: send WS messages straight from the Replay page. - Custom Extractors in Automate: pull a regex match into its own results column. - StreamQL: filter WS messages in WS History.

Have you tried the open source AI hacking agent Strix? 🤖 Strix integrated Caido as their proxy of choice to provide observability, human-in-the-loop and shared context to the agents. We are now working on native guardrails. If you are building AI hacking agents, we can help you too!
