Show HN: BinRev - Free, no registration web based (un)known binary analysis tool

Backstory: I have a keen interest in security from multiple viewpoints, and analysing a unknown firmware file format has been a topic which has popped up every once in a while but I have not found a tool which would be a) FREE and/or b) worked the way my brain does.

So when thinking of a use case to test an AI coding capabilities with, a "but what if...?" moment came.

So BinRev came to be as a test/review project for an AI particular coding agent, but since the initial code, I have used multiple different tools & models to polish it (see the readme in the repo for particulars).

What is it? I envision BinRev to be a tool which can be used to visually analyse the format of a known or unknown binary, build the understanding of the structure step by step and at any given moment export it in a machine readable format for further processing. It can already build a pretty complicated formats, but all testing and any input or collaboration is highly valued and welcome.

More details? - written in Typescript

- running locally in browser (should be able to work without any connection, but its not tested)

- no data is sent anywhere

- nothing is analysed but the binary

- no registration or signup

- quite certainly contains plethora of bugs (although I have done my best to iron some out)

- completely free

BinRev is open source, GPLv3, contributions are warmly welcomed. Source: https://github.com/dmonizer/binrev
