LoomAutomate the last mile of your GitOps

Declarative, composable modules that turn parameters into pull requests. One command, done.

Declarative Workflows

Describe what should happen in a loom.yaml — or generate it programmatically with loom.jsonnet. Loom handles cloning, rendering, committing, pushing, and opening PRs.

Template Everything

File contents, file paths, shell commands, commit messages, PR titles — every string is a Go template.

Composable Modules

Build small, focused modules and compose them. A parent module orchestrates child modules with parameters flowing down.

Library First, CLI Fallback

Embedded Go libraries for Git, GitHub/GitLab APIs, and YAML patching. Falls back to local CLI tools when needed.

Patch, Don't Rewrite

Strategic Merge Patch and JSON6902 let you surgically modify existing YAML files without replacing them entirely.

Preview Before You Push

Dry-run mode shows what would happen. Diff mode shows the actual file changes. Local-run mode lets you inspect the result.
