You know the ritual. You write a tidy little Apex test, hit deploy, and then you wait. ☕ You alt-tab to Slack. You water a plant. You quietly question some of your life choices. Two minutes later the org reports back: failure on line 3. 🤬 You fix a typo, deploy again, and begin the sacred ceremony anew. 😵‍💫

What if that loop ran in seconds, right on your machine, with no org required?

This month we're sitting down with René Knierim, the developer behind Nimbus. It runs your Apex tests locally against an embedded PostgreSQL engine, with no scratch-org round-trip required. Feedback in seconds, right in your editor. It sounds a little heretical for Salesforce, and that's exactly why we want to talk about it. 🌩️

What to expect

This won't be a polished sales pitch. René will give Nimbus a proper hands-on tour: what it does, how it actually pulls off local Apex execution, and where the bodies are buried. Then he and Roman get into the real conversation:

• a live walkthrough of Nimbus: Dev UI, watch mode, the CLI, the whole toolbox

• the honest version: what works beautifully, and what was genuinely painful to build

• the case for local-first, source-driven development, and why René bet on PostgreSQL under the hood

• the eternal Apex testing debates: coverage theatre, mocking, fflib, governor limits

• war stories, dead ends, and the occasional "wait, that actually works?"

• and of course, plenty of room for your questions in the live Q&A

It's online, so bring your favourite drink, let the dog supervise from your lap, and keep your mic muted if you want to refactor something on the side while you listen.
