Limrun alternative: what Sidekick does differently

The closest match on this site — we add TV, tests that outlive the agent, Play submission and a public price.

Limrun is the closest thing to Sidekick anywhere: remote Xcode sandboxes with version pinning and S3-backed caches, cloud iOS simulators and Android emulators, per-instance tokens for sandboxed agents, batch actions with millisecond precision, 60fps recording, SDKs in three languages.

The differences are at the ends of the loop and in the open. Sidekick adds TV devices, tests that survive the agent (record-replay, visual regression, CI checks), Google Play submission, published pricing with a free tier — and every line of it is source-available under FSL.

$ sidekick agent-setup   # skill + MCP, one command
$ sidekick xcode build . --scheme MyApp   # no Mac needed
$ sidekick ios create   # agent drives, you watch in the browser

Where Limrun is stronger

Deeper build sandbox + fleet ops

Xcode version pinning, per-instance credentials, jurisdiction pinning (us/eu/as), per-instance timeouts. Running 100 sandboxed agents is a problem Limrun has thought about harder than we have.

60fps video as a first-class verb

Limrun records sessions; we take per-step screenshots inside tests. For demo videos today, they win the row.

Which is yours: a decision guide

Sidekick

You ship a TV app: Sidekick runs tvOS/Android TV with d-pad verbs. Limrun's own guide says tvOS schemes don't support simulator attachment yet.

Sidekick

You want tests that outlive the agent: Sidekick record-replay + visual regression + CI checks (roadmap, dated). Limrun points at 'your favorite framework' — legitimate, and a different product.

Sidekick

You submit to Google Play from the terminal: Sidekick submits to TestFlight and Play. Limrun documents App Store upload only.

Limrun

You run a fleet of sandboxed agents across regions: Limrun. Per-instance tokens and jurisdiction pinning are documented; our region pinning is roadmap.

Sidekick

You need the price before you start: Every Sidekick plan is public with a no-card free tier. Limrun publishes its model, not its numbers.

Frequently asked questions

Is Sidekick a Limrun clone?

It started as a source-available answer to Limrun's closed platform — same high-level interface (remote builds, cloud sims, agent skill) so migrations are trivial. It diverges in TV coverage, post-agent testing, Play submission, self-hosting and license.

Can Limrun run tvOS apps?

Its CLI guide says tvOS/visionOS schemes build but 'do not support simulator attachment, installation, or XCTest yet'. Sidekick attaches TV devices with d-pad and focus-walk verbs.

What does Limrun cost?

Its homepage says pricing is split between idle and build time; no plan or per-minute price is published. Sidekick lists every plan (Free/Dev/Team/Scale) plus $0 self-hosting.
