GUN is running in production with 8M monthly users.
On large sites like HackerNoon and with Internet Archive.
What makes you say it is unstable?
If there is anything, please report it and we'll get it fixed.
Edit: Re grandparent: Will try to add "dark mode" to docs, in meanwhile, check out the docs on plain-text GitHub wiki ( https://github.com/amark/gun/wiki/Graph-Guide ) which is where everything pull from anyways.
