Hey HN. Graph Compose is a hosted platform for orchestrating API workflows on Temporal. You define workflows as graphs of nodes (HTTP calls, AI agents, iterators, error boundaries) and everything runs as a durable Temporal workflow under the hood.Three ways to build the same graph: a React Flow visual builder, a typed TypeScript SDK (@graph-compose/client), and an AI assistant that turns plain English into a graph.Open-core: the execution foundations and integrations service are AGPL-3.0. The platform orchestrator, visual builder, and AI assistant are proprietary.Longer backstory on why I built this in the first comment. Would love feedback, especially from anyone who's dealt with the "services work fine, the glue between them doesn't" problem.Docs: https://graphcompose.io/docs

Could you build this?
Partial The visual DAG editor and dynamic workflow generator are straightforward, but running a managed, multi-tenant hosted Temporal execution service requires deep distributed systems engineering.
What it would actually take: The system requires a React Flow frontend coupled with a backend orchestrator that dynamically translates JSON node graphs into Temporal dynamic workflows or custom worker loops. The hardest component is safely hosting and isolating untrusted user execution, managing a large-scale Temporal cluster with custom activities, secrets management, and robust rate/fault domain isolation across tenants.

Competitors mentioned: n8n, ActivePieces, Zapier, Make, Temporal
Concerns raised: Workflow governance and control (ownership, versioning, approval, change control, audit history, environment promotion, rollback), Smaller integration catalog compared to competitors, Product boundary unclear between Graph Compose and upstream systems like Konekti, Tightly coupled to Temporal, limiting flexibility, Crowded market with many existing solutions
Feature requests: Easier integration with other durable execution layers beyond Temporal, Batch error debugging and visibility improvements, Build integration catalog to match competitor offerings
