Our sandbox benchmarks now have an interactive results explorer and a refreshed run covering 11 environments. Pick any metric and percentile, share the view.

<p><strong>TL;DR:</strong> We've added an interactive results explorer to <a href="/hpc-sandbox-benchmarks">High Performance Sandbox Benchmarks</a> and refreshed the underlying run. It now covers 11 sandbox environments, up from 6. The harness and every raw run are still open source at <a href="https://github.com/starslingdev/hpc-sandbox-benchmarks" target="_blank" rel="noopener noreferrer">starslingdev/hpc-sandbox-benchmarks</a>.</p><p><a href="https://starsling.dev/blog/results-explorer-and-updates-for-high-performance-sandbox-benchmarks">Read the full post on starsling.dev →</a></p> tag:starsling.dev,2026:blog/introducing-ci-score-an-ai-coding-agent-skill-that-grades-your-github-actions-setup 2026-07-30T00:00:00.000Z 2026-07-30T00:00:00.000Z Yonas Beshawred

Check your GitHub Actions against best practices. ci-score is a free, open-source agent skill that grades your config and ranks a fix for every gap.

We benchmarked cloud sandbox providers (Blaxel, Daytona, E2B, Modal, Novita) on real CI workloads and open-sourced the results. Startup speed isn't the story.

<p><strong>TL;DR:</strong> After running 500K+ sandbox jobs in prod, we've <a href="https://github.com/starslingdev/hpc-sandbox-benchmarks" target="_blank" rel="noopener noreferrer">open-sourced benchmarks</a> for cloud sandbox providers using real-world CI workloads. For our workloads, sandboxes from Blaxel and Daytona's microVMs have excellent performance.</p><p><a href="https://starsling.dev/blog/beyond-cold-starts-benchmarking-sandboxes-for-real-workloads">Read the full post on starsling.dev →</a></p> tag:starsling.dev,2026:blog/introducing-ci-speedup-an-ai-coding-agent-skill-that-analyzes-and-fixes-your-slow-github-actions 2026-07-21T00:00:00.000Z 2026-07-21T00:00:00.000Z Yonas Beshawred
