Hey, yeah this looks somewhat similar to what we're building at https://webapp.io (nee LayerCI, YC S20)
We migrated to a fork of firecracker, but we're a fully hosted product that doesn't directly interact with GHA at all (similar to how CircleCI works), so there's some positioning difference between us and OP at the very least.
Always happy to see innovation in the space :)

Love TimescaleDB, actually used it for one of our recent product feature launches: https://webapp.io/blog/storing-millions-of-vm-metrics-with-timescaledb…

Hey HN, Josh here. I’m a frontend developer at a devtools company, and I keep noticing obvious mistakes like typos and accessibility problems make it into production.
I wanted to find something like pagespeed insights that would run against commits when they were first pushed, instead of after changes were deployed
That’s why I built Website Linter, a zero-configuration tool that scrapes pages on your site to find layout, spelling, and accessibility issues. It also gives you screenshots of the above-fold content across multiple device sizes.
Horizontal and spelling errors are easily overlooked during code reviews, which is why they enter prod often. Website linter helps you catch those issues as they appear instead of weeks later.
Under the hood, website linter uses:
- Lighthouse to get performance metrics and screenshots for different device sizes
- Pa11y to find accessibility issues
- Chromedp in Go to get HTML nodes that are larger than the width of the screen
- Fuzzy (in Golang) to find spelling errors on a trained dictionary (using a cleaned version from the words_alpha.txt file here: https://github.com/dwyl/english-words
I built Website Linter by re-using the infrastructure from the startup I work for, but you can use it on any internet visible page. Would love to know if you try it out!
To see what it looks like, visit here: https://webapp.io/website-linter-report/0 for a sample report (netlify’s homepage) or install webapp.io on GitHub:…

My hobby is collecting corporate/startup engineering blogs. It tends to be the first link I open whenever I chance upon a new website.
Here's are some of my favourites.

Another article I saw on HN awhile back where someone did this:
https://webapp.io/blog/postgres-is-the-answer/
I think its a reasonable option and the webapp.io people scaled it out pretty high. At Zapier we utilize RabbitMQ heavily and I cannot imagine scaling the amount of tasks we handle each day on postgres.
This article mostly is lesson learns and misconfigurations of RabbitMQ though. Which is probably a good reason to simplify if you don't need its power. No reason to have to learn how to configure it if postgres is good enough.

Your Docs [0] and Examples[1] page, or many [2] other page in the footer for that matter, return a blank page?

Firefox, latest version, no ad blocker enabled.
After nosing around in your source a bit, it seems the redirect to https://docs.webapp.io doesn't work for me?

What other examples are there of "single dependency stacks"?
This article is really about the versatility and reliability of postgres.
And I'm all in agreement.

As much as HN could lead you astray with the hype of this and that tech, articles like the above are some of the most consistently upvoted on this website.

The Beta account is free and includes:
> Three web apps on our globe-spanning serverless network, no matter how big. Plus, unlimited CI/CD time, and unlimited CDN.
I wonder if they'll hit crypto mining issues as other CI/CD providers have recently [0]. Apparently, free tiers are not sustainable due to crypto mining attacks.
