Eraserbot

Eraserbot is an automated tool for development teams that generates and updates codebase diagrams. It integrates with Git, so when code changes, the relevant diagrams are regenerated and documentation stays in step with the repository. It records version history so you can trace how a diagram evolved, and it can watch specific files or directories so updates only fire when something relevant moves. It also visualizes Terraform, CloudFormation, and Kubernetes YAML configuration. A free plan covers individuals and small teams, with paid plans for enterprise needs.

The reason this matters is that architecture diagrams rot almost immediately. A diagram drawn at the start of a project is wrong within a month, and nobody enjoys being the person who redraws it after every merge. Automating the regeneration means the diagram reflects the repository rather than someone's memory of it, and the version history gives you a record of when the picture changed.

- Generate architecture diagrams from a repository

- Keep diagrams updated automatically after each change

- Visualize infrastructure configuration files

- Track diagram history and review past versions

- Share a single place for team documentation

- Development teams whose diagrams go stale within weeks

- Platform engineers documenting cloud infrastructure

- Open-source maintainers who need an architecture overview

- Teams preparing for an architecture review or audit

Diagram quality depends on how the code and the monitoring rules are structured, so a messy repository can produce a messy diagram, and an automatically generated picture is not automatically a readable one. Granting repository access to a third party is a security decision that needs approval, especially for private code. Enterprise features such as larger team support sit behind paid plans, and the boundary between free and paid can move. Generated diagrams still deserve a human read before they are used in an audit or an external document.
