Conductor vs Inngest

Conductor is an Apache 2.0 open-source platform for building and orchestrating AI agents and workflows on a durable execution engine. It persists workflow and task state, allowing recovery after worker or infrastructure failure, with retries, timeouts, pause, resume, and termination controls. Workflows can use nested loops, dynamic branches, sub-workflows, and thousands of tasks. Native AI features include LLM tasks, MCP tool discovery and calls, human approval steps, and vector workflows for retrieval-augmented generation. Agents from LangGraph, CrewAI, Google ADK, and the OpenAI SDK can be used. SDKs are listed for Java, Python, TypeScript, .NET, Go, Ruby, and Rust. Conductor documents event-driven and Agent2Agent integrations. It can run anywhere Docker runs, using Redis by default and Elasticsearch for indexing, with replaceable storage and queue backends. Plans include free self-hosted OSS and hosted Developer Edition options.

Inngest runs asynchronous code as durable functions for event-driven workflows, background jobs, and agents. Its execution steps handle retries, retain state, and recover from failures; traces show activity from trigger to completion. Flow controls manage concurrency and fairness when users compete for resources. Developers can use open-source SDKs for TypeScript, Python, and Go, or the REST API. Functions can run wherever an app is hosted, with deployment guides for services including Vercel, Netlify, Cloudflare Pages, Render, and DigitalOcean. Inngest also describes isolated sandboxes for testing changes and tools for scoring and comparing variants on production traffic. The Free plan includes 5 seats, 50k executions, 500k events ingested, and 24-hour trace history. Execution pauses when the free quota is reached until the account upgrades. Pro starts at $99/mo. Inngest states that it is SOC 2 Type II compliant, and that its US-based databases are encrypted at rest and application traffic uses TLS/SSL in transit.
