Workflow & graph engines

Provides low-level orchestration for long-running, stateful agents with durable execution and human-in-the-loop capabilities that typical stateless workflow engines do not emphasize.

An event-driven, open-source orchestration platform that combines a declarative YAML workflow model with a rich plugin ecosystem and a visual editor for building and running workflows across environments.

Orchestrates and verifies multi-step work by discovering and assigning local Skill modules and enforcing end-to-end checks with resumable state.

Enterprise-grade agentic workflow platform with built-in RPA and high-availability focus for production deployments, unlike many prototyping-focused workflow engines.

Combines a public, curated catalog of reusable agent loops with an installable in-agent skill that discovers, crafts, audits, runs, and prepares loops for publication.

Implements the Depth Tree decomposition with a strict, evidence-backed runnable gate ledger that enforces approvals and re-verification for substantial agent tasks.

Graph-powered, agentic workflows for end-to-end multimodal video understanding, editing and remaking with iterative self-evaluation.

Provides a local-first operating layer for Hermes that enforces explicit evidence boundaries and verification gates while keeping executors and provider access observable.
