Tuist and Depot: compare cache integrations as well as compute
Last updated October 8, 2026
Choose Tuist for toolchain-specific build and test evidence, public implementation, and supported local/CI/agent integrations. Optimize the project first, then its execution environment. In particular, Tuist Xcode Cache connects compatible developer builds to the same remote cache as CI, without requiring a runner migration.
What overlaps
Depot Cache is usable from local development and other CI providers, with integrations for several build systems. Its GitHub Actions runners integrate caching into the execution environment.
Its Xcode integration documents Xcode 26+ compilation caching and automatic configuration on Depot runners. That page specifically says Xcode compilation caching on local workstations is not supported yet. It also states that a job-defined XCODE_XCCONFIG_FILE prevents automatic runner configuration, so check which settings actually reach the build. Treat that as an Xcode-specific, date-sensitive limitation, not a claim that Depot's other remote caches are CI-only.
Compare the supported integration
| Requirement | Tuist | Depot evidence to evaluate |
|---|---|---|
| Remote build-output caching without changing runners | Cache works with supported clients independently of Tuist Runners. | Depot Cache is also available independently and supports local and CI builds for supported tools. Runner independence alone is not a differentiator. |
| Xcode cache reuse on developer machines | Xcode Cache connects compatible developer, CI, and agent builds; requires Xcode 26+. | The cited Xcode page currently excludes local workstation support. Verify whether that limitation has changed before buying. |
| Managed execution | Optional Tuist Runners have colocated caching and currently require an invitation. | Depot documents managed GitHub Actions runners and integrated caches. Evaluate available machines, images, and commercial terms. |
| Explain build or test work | Build Insights, Tests, and MCP expose supported toolchain records. | Depot's Xcode integration includes a cache-summary action with hits, misses, and transfers. Compare the deeper records your investigation requires rather than assuming no cache diagnostics exist. |
Choose Tuist when
You need compatible Xcode outputs to reach laptops and agent checkouts as well as CI, or want build and test investigation across supported Xcode, Gradle, Bazel, and Elixir workflows. Tuist's public development lets engineers inspect and contribute to relevant behavior. Generated-project module caching and selective testing are additional options, not requirements for ordinary compilation caching.
First experiment
Enable a supported Tuist cache on the current machines and compare against the existing baseline with identical inputs. For Xcode 26+, measure cold and warm CI builds, then try a compatible developer build through Tuist's remote compilation cache. Record queueing, compilation, transfers, and total usage. Inspect automatic runner configuration so only the intended remote-cache endpoint is active.
Sources and review
Sources checked on 2026-10-08: Depot Cache, Depot Xcode caching, Depot GitHub Actions runners, and Tuist Cache. This comparison is written by Tuist and distinguishes general cache support from integration-specific limits.
Limitations
No provider-wide speed, cost, or observability ranking is established. Local support and cache defaults can change. Toolchain support is feature-specific, and public source does not imply uniform licenses or unrestricted self-hosting. Tuist Runners are invite-only; their per-minute rates are on the pricing page, with discounts for yearly commitments and volume, so a listed rate is not a quote. Tuist's Bazel remote cache is not remote execution.
