Our second agent skill is live! Run /ci-score to check your repo against best practices and let your agent close the gaps. Just run `npx skills add starslingdev/skills` starsling.dev/ci-score

@MarcusWilstrup @shivon Hey hey now, we like StarSling 💫

@shivon I was thinking “Starsling”, but Moonshot is much cooler 🌖

Pretty please call this “moonshot”

Last week we launched a reliable benchmark that measures sandbox performance for real workloads 📊 github.com/starslingdev/h…

fantastic work from the team! Tons of fun partnering with the cracked team at @starslingdev to make their runners real fast.

🚀 github.com/starslingdev/h…

@HeyGarrison THANKS! You guys were our inspiration :)

@starslingdev VERY COOL

Nobody should have to take our word for it. @starslingdev open sourced the benchmark they built during their EC2 migration. @blaxelAI was the only provider ranked in the top two across all six measured performance dimensions. x.com/starslingdev/s… Run it against your own workload.

Once we decided to migrate off of AWS, I set out to answer a simple question: which sandbox actually finishes real tasks fastest? The results for our workloads: 🥇 @daytonaio 🥈 @blaxelAI 🥉 @modal 4) @novita_labs 5) @e2b

@AniC_dev We’re accepting PRs! github.com/starslingdev/h…

@starslingdev curious what box.ascii.dev results would be happy to give credits/sub for that end

Finally realest benchmark in sandboxes space! In general, love the trend of benchmarks going beyond basic and overly general workloads and focusing on real world applications.

@borna_perak Thanks a lot! And yeah no one just starts a sandbox and goes on with their day lol

Our fist agent skill is live! It analyzes real GitHub Actions workflow runs, identifies the checks blocking your PRs, and drafts fixes like sharding tests, improving caches, or shortening checkouts. starsling.dev/ci-speedup

Introducing /ci-speedup Agents write a lot of tests which slow down your GitHub Actions over time. This fixes that. Works with any runners, uses the gh CLI and any coding agent. npx skills add starslingdev/skills

The biggest savings we've seen for customers have come from going from self-hosted runners to ours. Our agents make sure your tests are running on the right number of cores and are saturating the cores. Full details on how we got a customers a 13x cost reduction: starsling.dev/customers/part…

@starslingdev why is it so cheap? does it run on Hetzner?

🗣️ Starting today, StarSling Runners are generally available! StarSling Runners are an AI-native, drop-in replacement for ubuntu-latest that make your GitHub Actions up to 6x faster and 13x cheaper 🚀 Everyone has the option of getting fast CI runners now. What nobody has is CI that adapts and improves itself. 🎉 StarSling has now run over one million CI jobs for companies like @better_auth, @mastra, Partcl, and more. If your team runs CI on GitHub Actions using ubuntu-latest, you're now just a one line change away from faster runs. Check out our Launch YC! ycombinator.com/launches/R7B-s…💫

StarSling Runners are now in GA! We did a ton of infra work to make our runners self-serve and are super excited that anyone can try them out now. One customer who works with the frontier AI labs just signed up and migrated two of their most problematic workflows over to StarSling and saw an immediate 50% speedup in their jobs 🏎️ Every team should have faster, smarter, and cheaper CI.
