Why people consider alternatives to Lucid Train
Lucid Train is a systems-design-first coding harness that generates architecture diagrams directly from your codebase. Point it at a repository, and it draws the architecture, then hands that diagram to a coding agent as a specification.

- Pricing at scale as usage or premium tiers add up.
- Missing integrations with the rest of your stack.
- Performance or scale limits as your needs grow.
- A specific feature gap you have hit in developer tools.
