Orch8 – Durable workflow engine in Rust, one binary, Postgres or SQLite
Temporal's durability guarantees in one Rust binary — no Cassandra cluster required.
SQLite extension + bindings for Postgres NOTIFY/LISTEN semantics with durable queues, streams, pub/sub, and scheduler
WAL-based push semantics eliminate polling—Redis queues without the Redis.
Developers using SQLite who need pub/sub without adding Redis

Temporal's durability guarantees in one Rust binary — no Cassandra cluster required.
Postgres memory layer with claim truth-state resolution; fallback-safe when LLM keys missing.
Graph semantics on Postgres without Neo4j infra overhead or hand-rolled boilerplate.
Neon-like branching for self-hosters, but explicitly admits it's not for critical production workloads.
Upstash-compatible Redis on Cloudflare's free tier with 5GB storage.
Ditches Redis entirely by leveraging Postgres LISTEN/NOTIFY for instant wakeups.
