What customers are saying

Real teams shipping faster CI with StarSling agents.

Abhi Aiyer

Co-founder & CTO, Mastra

HUGE props to @yonasbe and @dbworku for helping us speed up our CI! PLUS the starsling bot continually finding optimizations for us. At Mastra we move so fast that the bottleneck becomes reviews and CI. Time spent compounds and @starslingdev helps you realize how much time you're losing.

Beka

Founder, Better Auth

We've been using @starslingdev for better auth CI :> it's been saving us countless hours! both with fast runners and their agent optimizing our CI. huge congrats on the launch!!

AI in your CI

StarSling Runners are faster, smarter, and cheaper.

Faster Builds

5th Gen AMD EPYC processors with zero-config caching that's 4X faster than GitHub

—5th Gen AMD EPYC (30% faster than GitHub)
—Unlimited concurrency

Self-driving

AI agents deep-scan your workflow runs and ship optimization PRs

—Caching — detect missing or misconfigured caches
—Dependency installation — implement faster install strategies (e.g., frozen lockfiles, parallel installs)
—Build steps — parallelize, remove redundant and optimize slow steps
—Tests — detect misconfigured test jobs and test database interactions
—Workflow structure — implement job splitting, matrix strategies, and dependency ordering

Cheaper Than GitHub

4 vCPU Linux runners with 16 GB RAM at usage-based pricing

—$0.008/min vs GitHub's $0.012/min (33% cheaper)
—Queue time never billed
—AI optimizations included
—No seat fees

Real PRs from StarSling agents

Pull Requests merged by customers. StarSling agents analyze and optimize your CI automatically.

ci: shard E2E kitchen-sink across 3 parallel jobs

chore(ci): optimize Playwright browser installs in E2E

chore: fix turbo cache configuration in ci

test(chroma): reduce fixed 2000ms waitForIndexing sleep to 200ms and add Docker healthcheck

test(couchbase): optimize vector test suite by replacing fixed sleeps with bucket.ping()

Install with a one-line change

Drop-in replacement for ubuntu-latest.
