One of my favourite things about being a software developer in 2025 is the ever-increasing ability to quickly spin up side projects and tools that don’t make economical sense and don’t teach you enough to justify much effort. For example, I’ve made a tool called Screenshooter, which is an entirely client-side screenshot stylising tool. It lets you upload an image or screenshot, and then apply simple skew, zoom, and grain effects, for consistent images for social media and so on.

Claude 3.7 Sonnet and I have vibe coded automatic OpenGraph image generation for Hugo. I found a bunch of other ways of doing this like I linked to before, but this uses an incredibly simple technique: use the canvas library to draw the logo and post title, and save the image. It’s much simpler than trying to wrangle Puppeteer or Playwright, which are great but huge overkill for the simple text-heavy styling of this site.

As I’m working on my new AI startup Rivets, I’ve been setting up a GitHub App. That’s not an OAuth app, but the second type they provide, where the app can operate as itself as opposed to operating as you on your behalf. There’s an excellent PHP library lcobucci/jwt available to handle the meaty parts of generating JWTs, but I had some trouble getting it working with GitHub Apps specifically, as there are some quirks, and not a huge range of examples.

The more I use Coolify, the more I’m impressed by it. It’s a great alternative to platforms like Laravel Forge, Vercel, Heroku and others. Following on from my previous post about setting this up, I’ve also published a Github repository to make it easy to get started. Coolify handles everything I’ve thrown at it, and I’m using it in production with PHP, Node, Python, Postgres, and MySQL. If you work across different technologies or like to experiment, it’s never been easier to take back control from the cloud and run things on your own servers.

I’ve recently had to shut down some old platforms. This presented an interesting challenge, as I had some requirements: No ongoing server costs/maintenance Custom error messages depending on the domain, so the solution can be applied to multiple legacy platforms Work across wildcard subdomains, which are used to identify the tenant I already manage DNS through Cloudflare, and after investigating their Workers a little bit, I found that they provide the perfect solution.
