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

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

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

  • tangent plugin scaffold – Generate plugin boilerplate
  • tangent plugin compile – Compile plugins in WASM
  • tangent plugin test – Run plugin test
  • tangent bench – Measure throughput and latency before deploying
  • tangent run – Start Tangent Runtime

  1. Use real languages, not DSL – Real Code > DSL. Reviewable, testable, LLM-friendly.

  2. Catch breakage before product , tangent plugin test For purity; tangent bench For throughput/latency.

  3. shareable and secure – Data transformations are easy to write and sharePublish and search open-source plugins in the Tangent plugins library, Each plugin runs in its own lightweight sandbox,

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

The benchmarks are run nightly on a dedicated 16-core AMD runner. View the nightly benchmark.
