AI Analysis

●●SolidSlickBig Brain

Hosted Temporal with visual builder, but Temporal Cloud already exists.

Strengths

•Single JSON format works across visual, SDK, and AI input methods
•No Temporal cluster management or worker deployment required
•Automatic retries and durable state handled out of the box

Weaknesses

•Temporal Cloud already offers managed Temporal infrastructure
•Visual workflow builders exist in n8n, Zapier, Pipedream

Post Description

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.
