Repography is a micro-startup — one developer and one designer working on this alongside all our normal work, with no funding to support other roles. Therefore the tech stack is oriented towards low maintenance and easy scaling.
We make heavy use of the Google Cloud Platform with the addition of a couple of great services:
There are two services running on App Engine:
If you choose the command line option rather than installing the GitHub app then you'll be using a completely separate program written in Rust, to analyse your local commit history and upload to our API. I chose Rust in this case for performance and the ease of building static binaries for multiple platforms (thanks GitHub actions!).
To turn an SVG into a PNG ready for download or print, we have a final service running on Cloud Run. This allows us to go beyond the limitations of Cloud Functions (e.g. custom Docker container, more system resources) but on a similar cost basis.
Repography is a web app which creates data visualizations for your Git repos. You can use our command line script to try out Repography on any Git repo, or install our GitHub app.
