The short version

  • Each has a real cost: Azure Functions consumption plan free grant is capped at 1 million executions and 400,000 GB-seconds of resource consumption per month per subscription, billed per GB-second beyond that; 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.

What people use each for

The jobs each tool is most often brought in to do.

Azure Functions

  • Serverless application backendnot Garden
  • Scalable API endpointsnot Garden

Garden

  • A platform team whose integration test suite takes longer than the coffee break and needs caching to cut the loopnot Azure Functions
  • An organisation with thirty or more services on Kubernetes where docker-compose no longer approximates productionnot Azure Functions
  • Giving every developer an ephemeral namespace instead of queuing for one shared staging environmentnot Azure Functions
  • Running the identical build and test definition locally and in CI so failures reproduce on a laptopnot Azure Functions

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Azure Functions

  • Consumption plan free grant is capped at 1 million executions and 400,000 GB-seconds of resource consumption per month per subscription, billed per GB-second beyond that
  • The newer Flex Consumption plan's free grant is smaller still, at 250,000 executions and 100,000 GB-seconds per month
  • Premium plan avoids per-execution charges but bills continuously for allocated core seconds and memory regardless of invocation volume
  • Memory is rounded up to the nearest 128 MB and execution time to the nearest 1 ms for billing, so small overages round upward

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 Azure Functions or Garden better?
Neither clearly leads. Azure Functions starts at Free and Garden at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, Azure Functions or Garden?
Azure Functions starts at Free and Garden at Free.
Does Azure Functions or Garden run on more platforms?
Azure Functions runs on Web. Garden runs on Linux, macOS, Windows, Kubernetes.
Can I use Azure Functions for free?
Both have a free tier, so you can try either at no cost before committing.
What is Azure Functions best used for?
Azure Functions is most often used for event-driven computing, serverless application backend, scalable api endpoints. Of those, event-driven computing and serverless application backend are not what Garden is typically brought in for.
What can Azure Functions do that Garden cannot?
Garden covers Action graph, Shared result caching, Remote Kubernetes environments, In-cluster builds.

Answered from the vendors’ own pages

Azure Functions: Does Azure Functions have a free tier?

Yes, Azure Functions includes a monthly free grant of 1 million requests and 400,000 GB-seconds on the Consumption Plan, or 250,000 executions and 100,000 GB-seconds on Flex Consumption.

Source
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.

Azure Functions: What is Azure Functions' pricing model?

Azure Functions uses usage-based pricing. Consumption plans charge per second of resource consumption and per execution, measured in gigabyte-seconds and rounded to the nearest 128 MB.

Source
Garden: Do I need Kubernetes?

Effectively yes. Garden is built around Kubernetes environments and offers little to teams on other runtimes.

Azure Functions: What is the minimum execution time for Azure Functions?

The minimum execution time is 100 milliseconds on Consumption plans. Premium plans charge based on core seconds and allocated memory.

Source
Garden: 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.
