kailash-enterprise
Kailash Enterprise — free to use · proprietary · source withheld · not open source. High-performance Rust-powered workflow engine, drop-in replacement for kailash.
Decision gist · record as of 2026-08-14
Yes, with conditions. Install if you are already using kailash and need performance without code migration, or if you are building new workflows and want Rust-backed execution. Do not install if you require open-source transparency or auditable source code—this is proprietary and binary-only. Verify the LICENSE-EULA terms and confirm that Integrum's support model meets your production requirements before committing. No known security vulnerabilities as of the query date.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.10 or later.
- NatsEventBus backend requires a separately managed NATS JetStream broker for cross-process event delivery.
- Medium install friction due to compiled wheels across multiple Python versions and platforms (cp310–cp314, macOS arm64, Linux x86_64/aarch64, Windows).

What it is and what it does
kailash-enterprise is a compiled Rust implementation of the kailash workflow orchestration engine, designed as a drop-in replacement for the open-source kailash Python SDK. It exposes the same API so existing code runs without changes, but trades source transparency for claimed performance gains. The package is proprietary and binary-only—you receive compiled wheels for Python 3.10 through 3.14 on macOS, Linux, and Windows, but not the Rust source.
The engine supports both a legacy v0.12 API (with deprecation warnings) and a new v2 API centered on NodeRegistry, WorkflowBuilder, and Runtime. It also includes a domain event bus (kailash.events) with two backends: InMemoryEventBus for single-process use and NatsEventBus for cross-process/cross-host delivery via NATS JetStream. The package maintains parity with the open kailash implementation through conformance test vectors, so capability divergence is treated as a critical incident rather than a test failure.
Use it for
- Replace kailash in an existing Python application without rewriting orchestration logic.
- Build AI agent workflows that require low-latency task execution.
- Distribute domain events across microservices using NatsEventBus for at-least-once delivery.
- Run workflow orchestration in resource-constrained environments.
- Prototype workflows locally with InMemoryEventBus, then scale to multi-process deployments with NatsEventBus.
