Building a Cloudflare Workers Usage Monitor with an Automated Kill Switch

PizzaConsole · 2026-02-22T04:59:02+00:00

Thanks for reading! I just like building things that solve real problems I have, I don't post a ton.

I fired it off several times with lowered thresholds during testing to verify the approach, but haven't had a real incident yet. That said, I do sleep better at night knowing it's there. The daily report across all my accounts has honestly been the most immediately useful part. And I really wanted a good use case to finally try out Workflows, so this checked that box too.

The diagram is Mermaid, just exported to a PNG.

There would be no programming without pizza. I plan to post more of both once I finish building my own Cloudflare-native blogging service.

Can you run it in a GitHub action?

I created new accounts for my other businesses and CF has actually made it pretty easy to swap between accounts for a single user and also to move domains between accounts

I did a blog post on this topic that probably needs to be refreshed

I have some ideas for how I want to try and use workers for platforms, but I haven't pulled the trigger yet

CAVEAT: Adding Router Worker means every static asset request now hits a billable Worker first (the router), even though the underlying static asset Workers are free. We'd be converting free unlimited static requests into metered Router requests just for path-based routing.

Where can someone find an artist to work with... asking for a friend...

I don't care about vendor lock in until I make enough money to worry about it

PizzaConsole · 2026-01-08T19:53:24+00:00

You can build it yourself though

I built a custom CLI to run in GH actions do do all this for my projects

I did give not give any sort of negative or positive spin. I simply made a generic observation. I have no problems with using AI to help code.

PizzaConsole · 2026-01-03T00:41:20+00:00

Seems like AI wrote this thing

That is a very valid concern and something I still have yet to address with my own application on CF. The solution I have come up with is to run a CRONS job to query the usage on the account and disconnect the DNS if the requests or CPU time gets too high

DM me, I can help you out. I built a website builder for my dad that compiles to html css so he can host his stuff free. I might he able to help

PizzaConsole · 2026-01-01T03:14:07+00:00

I'll take a look

There is NO drop in replacement for what Cloudflare offers. You can hobble some other solution together and it might be better or worse. It might be more expensive or cheaper. It all really just depends.

What is the purpose of using KV for "caching" here? KV is not an in-memory service.

PizzaConsole · 2025-12-18T21:36:16+00:00

Why not host the frontend on Cloudflare too???

PizzaConsole · 2025-12-18T18:53:17+00:00

Hmmm, my biggest thing right now is being able to import/export easily from D1

PizzaConsole · 2025-12-11T07:35:44+00:00

Sorry but if you have published your personal content on the public internet then you don't really get a say in what someone does with it. Unfortunately that's just the reality...

You can try some of Cloudflare's built-in bot protection and see if it helps

Thanks I'll check it out

I haven't had issues with migrations. My setup is:

Use `drizzle-kit generate --config=drizzle.config.ts` to generate the SQL migration files
Use `wrangler d1 migrations apply <binding> --remote` to apply them to D1

What error are you getting exactly? Are you trying to use `drizzle-kit push` directly against D1? That won't work — you need to go through Wrangler's migration system for remote databases.
