   Inngest has dedicated docs for durable agent loops: checkpointed steps that resume from the last successful point mid-run (docs-21, docs-33), a ReAct-style agent-tool-loop guide with retriable steps (docs-23), step.ai.wrap() for wrapping model calls as durable/observable steps (docs-22), sub-agent delegation and human-in-the-loop pause/resume patterns (docs-34, docs-35), plus general durable-execution/retry/memoization mechanics (docs-2, docs-15, docs-26). Community feedback corroborates reliability of the underlying durable execution engine in production use (inngest-comm-1, inngest-comm-5, inngest-comm-9).

   Restate✓fullclaimed8/10

   Restate documents immutable deployments and versioning explicitly: in-flight invocations continue running on the code version they started with, and retries are always routed to the same endpoint version, directly addressing safe versioning without breaking determinism (restate-docs-24, restate-docs-41). This is corroborated by broader durable execution guarantees (journal replay, exactly-once) that make this safe. missing for 10: independent/hands-on verification of version-pinning behavior in production, and detail on how new versions are rolled out/deprecated operationally.

   • [claimed-docs] “Restate then makes sure that requests start and end on the same version, by sending any retry attempts always to the same endpoint.”

   Inngest lets developers write ordinary TypeScript, Python, or Go functions with steps that are automatically checkpointed/memoized and resumed from the last successful point, with no YAML or proprietary DSL — supported by docs and corroborated by community devs praising the natural, code-first DX versus alternatives like Temporal. missing for 10: independent third-party benchmark or deeper multi-language proof beyond docs claims.

   Restate✓fullclaimed8/10

   Restate lets developers write handlers as ordinary code (TypeScript, Java/Kotlin, Python, Go, Rust) using constructs like ctx.run for automatic checkpointing of steps, with no YAML/DSL involved — confirmed by docs on durable steps, durable execution, and SDK support. missing for 10: independent hands-on developer testimony specifically praising 'no DSL/code-first' authoring (community evidence focuses on other aspects like cloud setup and architecture), and no direct comparison showing absence of any config-based workflow definition.

Composition

1. backend developerI compose workflows from parallel steps, fan-out/fan-in over dynamic batches, and child workflows without hand-rolling coordination

   weight 2 · round to Inngest
   Inngest~partialclaimed6/10

   Inngest's step model supports composing durable steps, invoking/deferring child functions/workflows, and waiting for events for fan-in-like coordination (inngest-docs-2, inngest-docs-4, inngest-docs-18, inngest-docs-35), all without manual queue/worker coordination (inngest-docs-1, inngest-docs-24). However, the evidence pack lacks explicit documentation of parallel step execution primitives (e.g., Promise.all across steps) or fan-out over dynamic batches specifically, so the 'parallel steps' and 'dynamic batch fan-out/fan-in' parts of the story are only inferred, not directly evidenced. missing for 10: explicit docs on parallel step execution syntax, explicit fan-out/fan-in over dynamic batch sizes, independent hands-on example of composing these three patterns together.

   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.

Language coverage

   weight 2 · round to Restate
   Inngest~partialcommunity5/10

   Docs confirm SDKs for TypeScript, Python, and Go with steps, retries, and flow control (inngest-docs-24, inngest-docs-25), showing multi-language support. However, there is no evidence addressing feature parity across these SDKs — most detailed docs, testing tools (Jest-compatible testing, ESLint plugin) and community feedback (inngest-comm-3) reference TypeScript specifically, suggesting Python/Go may lag behind. Missing for 10: explicit parity documentation across SDKs, Python/Go-specific testing and tooling evidence, independent confirmation of equal capabilities in non-TS SDKs.

   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.
