2026 Update on the #opa plugins for #backstage !

Despite being insanely busy with work things, have been able to push some cool features and updates!

- Some slight UX/UI adjustments to the docs site
- Updated a lot of the docs for more clarity
- Added an `opa-node` package for plugin authors to use in their backend plugins and modules to protect their API routes (just provide an input and an entrypoint and you're good to go!)
- Some framework updates (from backstage)

I am very happy with where these plugins are right now! Let's see if I get any other bright ideas 💡 to add some other features this year 👍

I love spacelift.io for a number of reasons, namely it saves you from running #Terraform or #OpenTofu in whatever "CI" tool your company uses this week (been there, hated it) and doesn't cost an arm, leg and kidney that Terraform Cloud charge you (loved TFC until that switcharoo).

Anyway, I've been wrapping up a thing I've been working on. Many SaaS tools allow you to send #webhooks, but rarely give you control over if, where and what is sent. Now #Spacelift let you control all of this using a Policy based on #OpenPolicyAgent.

SL provide an event, you develop your policy in the #Rego language, not only can you use that policy to decide: Is this an event I want to send a webhook for? But more than that, you can use the policy language to craft the exact payload. Since you may not get a choice of what that looks like on the other end.

Docs: https://docs.spacelift.io/concepts/policy/notification-policy

Now that's just for notifications etc. You can control almost anything within the tool: Logins, Plans, Triggers, Pushes and more.

Found while moving! Styra used to make a unique t-shirt for every #Kubecon back in the days. This was the first one made in the pandemic. Rudolph should have worn a mask though!

My talk "A decade of Open Policy Agent" is now on YouTube https://www.youtube.com/watch?v=I9T6FSnySOk

All the AI hype/hysteria had me rewrite parts of the talk mid-conference in order to try and tell a more human story — my own. But worry not, OPA and Rego got covered fairly well too :)
