Built an AI tool to visualize large codebases - would love feedback

13 pointsilia_khatko10 comments

Hi HN!

I’m a solo technical founder and just launched the first public version of Codemap AI (https://code-map.com) - a tool to help developers instantly understand large codebases.

Codemap AI currently:

- Parses large codebases (Java for now)

- Generates interactive relationship diagrams

- Lets you chat with an AI about your code

- Lets you chat with dev agents (developer clones) about code changes

- Tracks security issues and project statistics

- Helps with onboarding, debugging, and documentation

I built this because I’ve personally spent weeks trying to understand unfamiliar and legacy code in large projects. My goal is to make codebases as explorable as possible - like having a "Google Maps" for your code.

At this stage, it’s not a live SaaS - I have a landing page and a demo video here:

- Landing page: https://code-map.com

- Demo video: https://youtu.be/kMy-zwsApxI

Would love feedback from the HN community:

- Does this solve a real pain for you?

- What features would make it indispensable?

- Any suggestions for improvements or integrations?

Thanks - happy to answer any questions!

Congrats on the launch. I think you should have some pictures or diagrams on the main page to better explain what it does - the demo is good, but people want to see something up front, not necessarily watch a video.

And think about renaming the "Bugger Agent" ... Bugger has a particular meaning in English that you won't like.

Thanks for your comment! Will make some changes on the main page, thanks for expaining about "Bugger", didn't know that :)

We're using Github Copilot (the chat UI on github.com) to allow non-technical colleagues to ask questions of the code, "How does X business process work". It's deflected a lot of basic questions from engineers. Your product seems in this direction. Nice job

Thanks so much! Yes, we’re aiming to go deeper than just code chat - combining AI with structural diagrams and project insights to help teams understand architecture and workflows faster.

And we’re starting to onboard small teams for testing - happy to chat if this could be useful for your team!

Thanks for the feedback!

code-map.com timing out. appears to be a nice start, from video.

does code-map requires license from major model provider?

also, is code-map open source? how are new languages added?

Thanks for the kind words! Yes - landing is up at code-map.com, but looks like my hosting was a bit hammered before - I'll check it. Glad the video helped explain it - I'm still refining the landing page.

Good questions — here's some clarification:

1. License / model dependency Codemap doesn't require a license from a major model provider - it's designed to work with local models (Ollama, open-source LLMs), or users can plug in external APIs (OpenAI, Claude) if they want. The core parsing/analysis/graphing is independent of any one model.

2. Open source? Codemap itself is not open source - it's a commercial B2B product. Some parts (like parsers) may use OSS components, but the overall system is proprietary.

3. How are new languages added? Language support is modular: each new language needs a parser + chunker to feed the AI layer. Java is fully supported today. JS/TS are next. Python, PHP planned.

Certificate error on Safari iPhone btw.

I will take a look, thanks!

devin ai does this amazingly

Devin is amazing for code generation and automation - Codemap is focused on helping teams understand large codebases: visual architecture, AI docs, bug analysis, and team knowledge retention.
