Eraser AI - Codebase diagrams that update themselves

Hi Product Hunt! 👋

Every technical team wants great diagrams for their codebase, but they take forever to create and quickly become outdated. With Eraser AI, you can generate diagrams directly from your live codebase and keep them automatically updated.

Over the past two years, Eraser AI has generated 2.5 million+ AI diagrams, and today, we’re launching again with deep codebase integration and CI automation to make documenting your code easier than ever.

Here's what's special about Eraser AI:

⚡️ Codebase diagram generation – Create infrastructure, system architecture, data model, and app logic diagrams directly from your codebase. Eraser AI finds relevant files and generates accurate diagrams.

🤖 Eraserbot (CI action) – Automate your diagrams! Eraserbot monitors your codebase and updates diagrams whenever a PR is opened, keeping everything in sync without extra work. Set it up once and Eraserbot handles the rest.

💬 PR comments with visual diffs – Eraserbot adds visual context by commenting directly on PRs with the updated diagram. Speed up code reviews with visual references that instantly communicate changes.

Here are some prompt ideas for codebase diagrams:

• "Draw a cloud architecture diagram using .tf files in the /terraform/dev folder."

• "Draw a high-level flowchart of the new user signup process."

• "Draw a data model using the schema.prisma file."

• "Generate a sequence diagram for API calls in the handlers/ folder."

• "Generate a service architecture diagram for the payment-processing service."

Hello,
I have been using this product from almost 6 months now and it saved me hours of working. I even wrote about it on my linkedin https://www.linkedin.com/posts/mhgaber_good-morning-tech-entrepreneurs-as-someone-activity-7302277306041958401-YgGD?utm_source=share&utm_medium=member_desktop&rcm=ACoAAAPrHfoBaSLpVRL1yXCHr2Nam8t9QB5QSi4

Thumb up!

I've been using Eraser for a few months now and really love it. Thanks to markdown support and code block highlighting, it is particularly useful for maintaining documentation, system architecture overviews etc when diagrams and code examples live together.

One notable drawback is the lack of full keyboard support for navigation. I find it frustrating to switch between mouse and keyboard for certain actions. Enhanced keyboard navigation would greatly improve usability.

But overall, it's a good tool and a daily driver.

love the sound of this. upvoted and bookmarked. will give it a spin.

good luck with the launch

Awesome feature and video 😂 - How do you come up with these amazing product video demos.

he fact that the diagram gets automatically updated whenever a PR is opened, and you can instantly see the visual context of the code changes, is such a great feature. I’m curious about how this has impacted actual code reviews and what changes users have seen after using this feature.

Congrats on the launch, Shin! Eraser AI is a brilliant solution for automating and updating codebase diagrams—great for saving time and keeping documentation up to date!

I start all freelance and project work with eraser - user journey sketch in canvas, estimation in document. My goal is usually to present the project to non-technical people and eraser works just great for this task.

Just tried to generate a diagram from the repo with a small prompt - that's pretty sick!

Good luck with this launch!

This sounds super useful! Keeping diagrams updated is such a hassle, so having them sync with code changes is a big help. How does it handle large projects—can it focus on specific files or folders?

Congratulations on the Eraser AI launch! This is exactly what technical teams have been waiting for. The ability to generate diagrams directly from codebases and keep them automatically updated through CI integration solves a genuine pain point. Love how you've implemented the PR comments with visual diffs to make code reviews more intuitive. The automated diagram updates via Eraserbot is particularly clever - no more stale documentation! This tool bridges the gap between code and visual documentation in a way that feels seamless and practical. Excited to see how teams incorporate this into their workflows!

I've seen engineering teams using Eraser for the past year now and it's genuinely transformed how they manage their codebase documentation, even more so for complex microservice architectures. Eraserbot's AI-driven automation is the logical next step as it seamlessly integrates with the CI pipeline, ensuring that diagrams are always current and accurate.

What I heard engineers love most is how it simplifies the process of visualizing changes during PR reviews. It's not just about saving time, it's about maintaining clarity and consistency across the team.

So if you're tired of manual diagram updates and want to streamline your workflow, have your team try Eraserbot!

This sounds fascinating! How exactly does Eraser AI keep codebase diagrams updated? Are there specific integrations or workflows it supports for developers? Would love to learn more about its use cases.

Easy to use and fast to iterate with. I use it all the time in my CS classes at Harvard :)

It’s exciting to see products that actually make a difference. Wishing you all the success!

Awesome idea. My favorite tool is ilograph.com

Technical teams will find this helpful

Wow, very powerful! Excited to implement this in my code base

Ohh this looks awesome! So much time saved!

Future stuff: I can imagine moving around components in the diagram and having the code base change. So that you are essentially no-code edit.

Awesome idea. Will definitely give it a try
