It seems similar to sitespeed.io (also open source), which logs performance metrics to Graphite and offers dashboarding via Grafana. Any major differences?

From quick glance at falco documentation it appears to be much simpler to run and configure, on the other hand this can be also perceived as disadvantage because it offers less capabilities.

Curious to know how it compares to speedcurve (commercial SaaS). Other than being open source obviously :) No affiliation.

You might want to consider a name change. Falco is a container security tool that's in the CNCF: https://falco.org/

Also Falcon which is off by 1 letter, is a WSGI web library for Python, they both have a similar logo.

I've been using DEITY's Falcon https://github.com/deity-io/falcon it's a React frontend for magento or vendure or other ecommerce + wordpress for blog part + search with algolia, it's a modular approach I like

Fair point! I’m not much aware of the container space, which explains the overlap. I’ll consider finding another name (which is quite hard since I got used to Falco by now).

I thought this was it, as well. How about falk? Which is the norse name for falcon...

See if "Der Kommissar" is taken. :)

Just change it to Falko

Would you please remove the weird "emoticon key" thing at the bottom? You could almost certainly fit single-letter keywords (the values of the emoticons) in similar space, without forcing everyone to go to a new page and cross-reference. I guessed computer meant programming, and that the palette represented art, but couldn't figure the rest out. There's no point in using short symbols everyone knows.

Each one shows what they represent when you hover.
