Hello! 👋
I'm a full-time open source developer.
My open source projects...

make the Web safer and more private.

Caddy is the only web server to use HTTPS automatically and by default
CertMagic is a Go library that provisions and manages TLS certificates for servers
ACMEz is a fully-compliant RFC 8555 (ACME) implementation in pure Go

make developer lives easier.

PapaParse is a JavaScript library that parses CSV files
JSON-to-Go converts JSON to Go structs
curl-to-go converts curl commands to Go code
Archiver is a Go library for working with archive formats
libdns is a set of universal DNS record manipulation APIs

preserve personal and family history.

Timelinize stores all your digital life onto a single timeline, stored locally

are often used in humanitarian and non-profit efforts.

PEPFAR uses Caddy to collect medical data in the field
The United Nations, Wikimedia, and several other public agencies use Papa Parse to process data

My primary work is the Caddy web server. Caddy has:

📄 >20 million TLS certificates under management
⏬ >50 million downloads
🐳 >500 million Docker pulls
🔐 >1 trillion TLS connections secured
📈 >10 TRILLION ‼️ HTTPS requests served

That's a lot of public good for a free project maintained by ~1 developer! Thankfully, Caddy has over 300 contributors. But coordinating that effort takes a lot of time and energy, so I now accept sponsorships to help fund ongoing maintenance of my projects.
Your sponsorships make a difference because although open source work can be satisfying, it is often a drain on mental, emotional, and physical energy. In addition to making full-time development possible, sponsors provide much-needed relief, leading to happier, healthier, less-stressed developers.
My goals for my projects are:
