Cloud Custodian

0.9.53.0 open-source

Cloud Custodian is a rules engine for managing public cloud accounts and resources across AWS, Azure, and GCP using YAML-defined policies.

Summary

Cloud Custodian is an open-source rules engine, released under Apache 2.0, that lets organizations replace the ad hoc scripts they use to manage public cloud accounts with a single policy layer, defining rules in YAML that filter resources and act on them. It runs as a command-line tool, either invoked directly, scheduled as a cron job against existing infrastructure, or bound to serverless event streams for real-time enforcement, which makes it suited to cloud platform and security teams responsible for AWS, Azure, and GCP compliance, tagging, and cost cleanup rather than to application developers. Its README describes it as a CNCF Incubating project consolidating what would otherwise be dozens of separate cloud-management scripts into one tool. With 593 contributors, 250 commits in the past year, and a release only 85 days ago, it remains under active development since its first commit in 2015.

Cloud Custodian is a rules engine for managing public cloud accounts and resources across AWS, Azure, and GCP using YAML-defined policies.

How Cloud Custodian helps

Which resources across my AWS, Azure, and GCP accounts are out of compliance with my security or tagging policies?

runs a YAML policy's filters against live resource inventory in the account and returns the matching set, with metrics and structured output describing what failed and why

Can I see what a policy would change before it touches anything?

supports a dry-run mode that evaluates the policy against real resources and reports what actions would fire without executing them

Will this policy actually catch something bad before it reaches production infrastructure?

runs the same policy against infrastructure-as-code assets on a workstation or in a CI pipeline, giving feedback before the resources are ever provisioned

How do I get notified the moment a resource violates policy, instead of waiting for the next scan?

binds the policy to the cloud provider's serverless event stream so matching actions run in real time as changes happen, rather than only on a schedule

How do I check compliance across many existing accounts without hand-rolling a script for each one?

runs as a scheduled job against a fleet of existing resources across regions or accounts, applying the same policy set and consolidating the results into one report

Lines in monospace are the tool's own words: help text parsed from its source, or an endpoint from its API document. Under release, a line is our summary of a dated release. Under docs, it is quoted from the tool's own documentation or website. Each links back to the source it came from.

Score card

  1. Shipping velocity releases a month, last 12 months
  2. Documentation quality release-notes rubric, 0–100
  3. Breaking-change discipline how rarely a release breaks users, and notice given
  4. Maintenance risk quiet time against its own cadence, maintainers
  5. Innovation & surface new capabilities, API and MCP surface
  6. Community health
  7. Contributor trend distinct committers, this year against last
  8. Maintainer concentration bus factor now against a year ago
  9. Issue backlog trend issues closed per issue opened, 12 months
  10. Responsiveness median time to a maintainer’s first reply

Nine scores for Cloud Custodian, each built from the releases, notes and API history this site tracks — and, on Researcher and Business, where it stands among every measured tool in its category and how that has moved.

Score cards are part of every paid plan.

See plans →

Each score is 0–100 on a published rubric, derived from data this site already shows. A dimension we cannot measure says so — it is never scored 0 and never enters a rank.

How this is scored
  • Shipping velocity — releases a month over the last 12 months, on a log scale where 16 a month scores 100. Needs 3 releases in the window.
  • Documentation quality — the release-notes rubric published on the analytics page, unchanged.
  • Breaking-change discipline — the share of releases carrying a breaking change (none scores 100, half or more scores 0). Only projects that label breaking changes are measured: a clean record cannot be told from an unlabelled one.
  • Maintenance risk — quiet time measured against the tool's own release cadence (quiet longer than 90 days and three typical gaps scores 0), plus the number of active maintainers and whether contributors are growing, where known. Higher is lower risk.
  • Innovation & surface — new capabilities in the feature ledger this year, API and MCP operations added, and the share of commits that are features: the mean of whichever we hold.
  • Community health (open-source tools only) — each is a direction, not a size: contributors this year against last, the bus factor now against a year ago, and issues closed per issue opened, where steady scores 50, doubled 100 and halved 0; plus the median time to a maintainer's first reply (an hour scores about 100, a month or more 0). A commercial card has no repository and carries none of the four.
  • Documented delivery (commercial tools) — when a vendor's documented new capabilities have slowed against its own baseline, that counts against the overall standing as heavily as two low dimensions. Steady delivery, or too little history to judge, leaves the standing alone; it is never a sixth score.
  • Open-source tools are scored on repository signals; commercial tools on their published changelog. Ranks compare tools within one category and one profile and need at least five measured peers; the overall standing needs three ranked dimensions. Best-in-breed or consolidator is a shape, not a quality, and is never scored.
