Artillery Cloud is now generally available. Biased, but if you need production-grade load testing it would be silly to use anything else.

Technological innovation can be a form of participation in the divine act of creation. It carries an ethical and spiritual weight, for every design choice expresses a vision of humanity. The Church therefore calls all builders of #AI to cultivate moral discernment as a fundamental part of their work—to develop systems that reflect justice, solidarity, and a genuine reverence for life.

Not ready to drop Node.js in production yet, but @bunjavascript has completely replaced Node.js for me for scripting and smaller apps. Those built-in Bun APIs for I/O, shell scripting and SQL are just so nice to use.

I wrote about my load testing journey and why I chose Artillery @artilleryio over JMeter and K6. Load testing shouldn't be a chore. medium.com/javarevisited/my-…

Artillery Cloud is now running on @PlanetScale Metal for Postgres. Instant performance boost vs AWS Aurora, and the built-in query analyzer already helped us fix a few issues. Such a great product.

Supabase has to be working on a Lovable competitor. Fits their "build in a weekend" tagline perfectly. They'd become a viable Replit alternative immediately. Replit right now is unique in how they have a full stack solution (there are others but no one has heard of them).

Very happy with this setup: Claude Code in the background doing grunt work - refactoring & fixing small bugs. Anything tightly scoped, boilerplatey, and where an existing test suite helps make sure it doesn't go off rails. Cline to do interesting new work, mostly in plan mode.

We've had a couple of really sunny weeks here in Ireland so @edmundojr_ went ahead and added light mode to Artillery Cloud

Know the codebase well + codebase is well-structured => get so much more out of AI. Use AI too freely => knowledge of the codebase drops + architecture suffers. Tough one to balance and another trade-off to now keep in mind when building.

This also means it's easier to justify time on refactoring something that's more of a "would be nice to" vs "has to be done to build new thing X" if it'll help AI. Especially if the refactor is also easier with AI.

Artillery Cloud went live 5 months ago. Since then: * 4k+ signups * All kinds of users- from startups to public companies. SaaS, security, adtech, gaming, events, fintech, crypto, AI * 100+ teams doing continous load testing (my favorite!) * Mostly product and QA, not SRE!

Looking at CI usage by @artilleryio users & GitHub Actions absolutely dominates: GHA is used in ~60% of all tests in CI GitLab a distant 2nd at ~16% CircleCI & Jenkins tied at ~6% each Google Cloud Build and Azure Pipelines at ~3% each
