Zitadel Nextgen is no longer event-sourced, but events are not going away. Relational tables hold the current state. Wide events provide the context needed for auditing, security, and integrations. Why we changed the architecture: eu1.hubs.ly/H0ypKPS0

15,000 GitHub stars! ⭐ A huge thank you to everyone who has starred ZITADEL, contributed code, reported issues, shared feedback, or supported the project. We couldn’t have reached this milestone without our open-source community. 🧡 eu1.hubs.ly/H0ymcrR0

AI agents need to register themselves. Now they can do that with ZITADEL. We’ve added OAuth 2.0 Dynamic Client Registration, enabling clients such as Claude Desktop and other MCP clients to register as OIDC applications at runtime. Learn more: eu1.hubs.ly/H0xLP2p0

We just shipped user schemas for the next Zitadel. 🚀 Your user model is a JSON Schema file in your repo now, not a fixed shape we hand you. Add fields, add schemas for machines and agents. Preview with `plan`, publish with `apply`. eu1.hubs.ly/H0x2pCM0

Yesterday Claude needed to check something on my machine, and it just did. Read the file, ran the command, moved on. I didn't think about it. That's what got my attention. Not that anything went wrong. That I've stopped noticing what I'm handing over.

2/ I work in identity and security. If a colleague described a system where access gets granted because "it's usually fine," I'd tell them that's not a policy, that's a hope.

3/ Built a 2-minute self-check to actually answer it for my own setup: what can your agent reach right now, does that access expire, could you cut it off in one move. tally.so/r/LZg11p Curious if anyone else has caught themselves doing thi

1/ AI is everywhere right now, and of course I had to try it myself. Everyone's talking about agents replacing engineers, so I asked Claude to set up auth in a Next.js app, completely on its own.

5/ Went in expecting a clean demo, got a bug report from an agent that debugged itself.

6/ What's your experience with AI agents so far. Would you trust one to do something like this fully on your behalf, no review? Want to try the new CLI? Let me know.

We've been working on something😃
Adding #auth to your project shouldn’t start with a dashboard detour 😆 With @zitadel/cli@alpha, you can start locally and get login + registration running in 57s. This is an early preview of where we want @zitadel developer experience to go. Let me know, do you like it or hate it?

The HackingLab Day "intern" stole the show! 👶✨ First talk back from maternity leave for @Zitadel. Husband was organizing, I was speaking, and the baby was bringing the laughs. The juggle is real, but it’s great to see it’s possible. How do you handle the family/work juggle? 👇

It has been a while since I checked the @github trending repos report, but out of sheer interest I took a look today and it brought me a lot of joy to see @zitadel back on the daily Go list. Building an open-source IdP means being buried in OIDC/SAML specs, dealing with multi-tenant data isolation, and optimizing for security, usability and reliability. It's plumbing that only gets noticed when it breaks😆 Thanks to the community for all the help and input, this truly helps us grow. github.com/zitadel/zitadel #go #golang #opensource #identity #iam

Code is becoming a commodity. Trust is the new product. A year ago @zitadel moved to AGPL 3.0. Everyone thought it was a move against cloud providers. That was true, but it wasn't the full picture. 🧵
