Lucid Train compared with OpenHands.
A platform with many surfaces, against a harness built around one idea.
OpenHands is an open-source platform for software engineering agents, offering a GUI for interactive sessions, a CLI for the terminal, an SDK for embedding and self-hosted enterprise deployment, alongside a hosted OpenHands Cloud. Lucid Train is narrower on purpose: a desktop harness whose distinguishing input is a generated architecture diagram that becomes an implementation specification. OpenHands is the broader platform; Lucid Train is the more specific bet.
Breadth against specificity
OpenHands gives you several ways to run an agent and a path to embedding one in your own product. That breadth is genuinely useful if you are building on top of agents rather than only using them. Lucid Train offers a desktop app and a CLI and nothing to embed, because it is a tool rather than a platform.
Isolation approaches differ
OpenHands has historically leaned on containerised execution, which is a strong answer to letting an agent run commands safely. Lucid Train uses risk-tiered approval with reviewable diffs, where safe commands run, riskier ones prompt and the catastrophic tier is refused outright. Containerisation is stronger isolation; approval tiers are lighter and keep the agent working in your real checkout.
The architecture input
This is the difference that is not a matter of degree. Lucid Train surveys the repository, emits a semantic graph, lays it out with a constraint solver, and can convert the result into a specification that starts a coding turn. Nothing in a general agent platform does that, and if it is what you want, breadth elsewhere does not substitute for it.
Open source and hosting
OpenHands is open source with a hosted cloud alongside it and self-hosted enterprise options. Lucid Train's CLI is free and open source; the desktop app is paid at $3 a month or $30 a year, and there is no hosted version at all because it is a desktop application by design. If your code cannot leave the machine, that design choice is the point.

Questions
Is OpenHands open source?
Yes, it is an open-source platform for software engineering agents, with a hosted cloud offering alongside it.
Does Lucid Train run agents in containers?
No. It uses risk-tiered command approval and reviewable diffs in your real checkout. That is lighter than containerisation and a weaker isolation guarantee.
