FilterNode
A webhook filter proxy. Point any webhook source — Slack, Stripe, GitHub, anything — at a FilterNode URL, set a few filter rules, and only the events that pass get forwarded to your n8n, Zapier, or Make. The junk gets dropped before it ever becomes a billable run.
~8ms overhead · no workflow changes · 5-minute setup

How it works
Your sources fire everything at FilterNode. It checks each event against your rules first, drops the ones that do not match, and forwards only the rest to your automation platform — so filtered-out noise never costs you a run.
I built FilterNode as a proper SaaS, but I'm not really trying to make money from it — it's here so other people can use it and get something out of it. It isn't free, and that's not about my wallet: a price tag is just the simplest way to keep abusers out so I don't have to police it. If you actually want to play with it, ping me and I'll upgrade your account.
