What is Tangent?

Tangent is a stream‑processing toolkit that treats plugins (user‑defined functions) as first‑class citizens – exceptionally easy to write and share. Perfect for vibe-coding those pesky log transformations.

Plugins run in a lightweight WASM sandbox with near-native speed and full language flexibility — no DSLs, no vendor-locked runtimes. Plugins are designed to be shareable, so common transformations (e.g. GuardDuty findings → OCSF) can be written once and shared with the community.

Tangent ships with everything you need to develop, test, and benchmark your own transforms:

• tangent plugin scaffold – generate plugin boilerplate
• tangent plugin compile – compile plugins to WASM
• tangent plugin test – run plugin tests
• tangent bench – measure throughput and latency before deploying
• tangent run – start the Tangent runtime

Why use Tangent?

1. Use real languages, not DSLs – Real code > DSL. Reviewable, testable, LLM‑friendly.

2. Catch breakage before prod — tangent plugin test for correctness; tangent bench for throughput/latency.

3. Shareable and secure – Data transformations are easy to write and share. Publish and discover open-source plugins in the Tangent Plugins library. Each plugin runs in its own lightweight sandbox.

Benchmarks

Benchmarks show end-to-end throughput with simple log transformation plugins implemented in Rust, Go, and Python. Each plugin is compiled to WASM and run inside Tangent.

Benchmarks are run nightly on a dedicated 16-core AMD runner. See nightly benchmarks.
