   Restate~partialclaimed3/10

   Restate's docs describe durable async/sync service invocation, coordination primitives, and event-based signaling that could underlie fan-out patterns, but none of the evidence explicitly documents parallel-step composition, fan-out/fan-in over dynamic batches, or child-workflow invocation as first-class constructs. missing for 10: explicit fan-out/fan-in APIs, dynamic batch parallelism, child/sub-workflow spawning and joining semantics, and any example or docs page dedicated to this composition pattern.

   • [claimed-docs] “Call services sync or async with guaranteed execution and exactly-once semantics.”
   • [claimed-docs] “Restate provides three durable coordination primitives for this: ... Communication between ongoing invocations, agent steering, and human ap…”
   • [claimed-docs] “Coordinate long-running processes, human approvals, listen to webhooks and other signals.”

   Trigger.dev~partialclaimed2/10

   Trigger.dev's own docs describe TypeScript/JavaScript (Node.js and Bun) as the core language, with Python support only 'via build extension' and no mention of Go or other languages at all — this is far from 'real feature parity' across multiple SDKs as the story requires. Missing for 10: native first-class Go SDK, native first-class Python SDK with parity (not a build-extension workaround), and any evidence of equivalent feature sets across languages.

   • [claimed-docs] “Language | TypeScript/JavaScript (Node.js and Bun); Python via build extension”
   • [claimed-docs] “All `v3` functionality is provided through the `@trigger.dev/sdk` module.”

   Restate~partialcommunity6/10

   Restate officially lists five supported SDKs (TypeScript, Java/Kotlin, Python, Go, Rust) covering the mainstream backend languages, and shows some cross-language evidence (Go/Rust client docs, Rust SDK typed ingress clients) alongside deep TypeScript-specific guides for durable steps, timers, error handling, and testing. However, most detailed capability documentation (ctx.run, error handling, testing, AI-assistant integration) is TypeScript-centric, with only shallow mentions for Go/Rust and none for Python/Java, and a community comment notes Go SDK was a later addition, suggesting the SDKs haven't always had lockstep parity. Missing for 10: explicit feature-parity statement across SDKs, equally deep Python/Java/Go documentation, and independent verification that all SDKs support the same primitives (workflows, virtual objects, timers) equivalently.
