+title: "Announcing Oolong: Lightweight TEA Implementation"
+date: "2025-10-30"
+---
+
+We’re excited to introduce Oolong - a lightweight, MIT-licensed implementation of [Transparency Exchange API (TEA)](https://github.com/CycloneDX/transparency-exchange-api) designed for simplicity and portability.
+
+Oolong is available on GitHub: https://github.com/relizaio/oolong
+
+## Why Oolong
+
+- **Lightweight by design**
+- **No database required**
+- **Git-friendly content model**
+
+Oolong serves TEA content directly from a set of YAML files, exposed via the TEA API. It also implements TEA discovery, including .well-known endpoint. This makes it ideal for simple setups, demos, CI pipelines, and GitOps-style workflows.
+
+## How It Works
+
+- **Content as YAML**. You define your TEA data in YAML.
+- **Served via TEA API**. Oolong reads YAML and returns it through standard TEA endpoints.
+- **Discovery**. Oolong implements TEA discovery, including .well-known endpoint.
+- **Straightforward operations**. No external stateful dependencies are required.
+
+## Run It Your Way
+
+- **Single container**
+- **Docker Compose**
+- **Helm chart**
+- Optional: **Gitpod sidecar** that periodically syncs content from a public Git repository
+
+## Manage Content with ReARM CLI
+
+We added helpful commands to ReARM CLI for both Oolong content operations and TEA API interactions:
+
+- Oolong commands: https://github.com/relizaio/rearm-cli/blob/main/docs/oolong.md
+- TEA operations: https://github.com/relizaio/rearm-cli/blob/main/docs/tea.md
+- Install ReARM CLI: https://github.com/relizaio/rearm-cli
+
+If you try Oolong, we’d love your feedback and contributions!
