Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Garden
- Incredibuild acquired Garden in November 2024 and the pricing page now redirects to documentation, so there is no public commercial offer and no published roadmap for a team betting a platform on it.
- It is tightly bound to Kubernetes, so teams running on ECS, Nomad, plain VMs or serverless get little from it and would need a different tool entirely.
- The YAML action graph is a real configuration surface: a large monorepo needs someone to own and maintain Garden config as a first-class artefact, which is a standing platform-engineering cost.
- Shared remote environments mean every developer needs cluster access and a cost allocation model, so cloud spend rises and namespace sprawl becomes a thing you have to police.
- Caching correctness depends on declaring dependencies accurately; an under-declared action will serve a stale cached pass and hide a genuine test failure, which is a hard class of bug to notice.

Questions people ask
- Is Garden or Keil MDK better?
- Neither clearly leads. Garden starts at Free and Keil MDK at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
- Which is cheaper, Garden or Keil MDK?
- Garden starts at Free and Keil MDK at Free.
- Does Garden or Keil MDK run on more platforms?
- Garden runs on Linux, macOS, Windows, Kubernetes. Keil MDK runs on Web.
- Can I use Garden for free?
- Both have a free tier, so you can try either at no cost before committing.
- What is Garden best used for?
- Garden is most often used for a platform team whose integration test suite takes longer than the coffee break and needs caching to cut the loop, an organisation with thirty or more services on kubernetes where docker-compose no longer approximates production, giving every developer an ephemeral namespace instead of queuing for one shared staging environment, running the identical build and test definition locally and in ci so failures reproduce on a laptop. Of those, a platform team whose integration test suite takes longer than the coffee break and needs caching to cut the loop and an organisation with thirty or more services on kubernetes where docker-compose no longer approximates production are not what Keil MDK is typically brought in for.
- What can Garden do that Keil MDK cannot?
- Garden covers Action graph, Shared result caching, Remote Kubernetes environments, In-cluster builds.
Answered from the vendors’ own pages
Garden: Is Garden still maintained?
The open source project remains on GitHub under Incredibuild ownership, but the commercial pricing page redirects to the docs and there is no public paid offer.
Keil MDK: Does Keil MDK have a free version?
Yes, Keil MDK Community Edition is free for non-commercial projects. Essential and Professional editions are available as monthly or annual subscriptions.
SourceGarden: Do I need Kubernetes?
Effectively yes. Garden is built around Kubernetes environments and offers little to teams on other runtimes.
Keil MDK: How much do Keil MDK paid editions cost?
Specific pricing for Essential and Professional editions is not published on the main site. Rates are available from the Arm Developer Tools store or by contacting Arm sales.
SourceGarden: Does it replace my CI system?
No. It runs inside GitHub Actions, GitLab CI or similar and speeds up what those pipelines execute.
Garden: What is the actual saving?
It comes from skipping builds and tests whose inputs have not changed, so the benefit scales with how many services you have and how often only a few change.
