SHLabs modules are free.
Time isn't.
Every module shipped here is GPL-3.0 and free to use forever. There is no paid tier, no commercial sponsor, no telemetry. Development time comes out of evenings and weekends. If a module has been useful — in a classroom, in your own research, or just for the pleasure of patching — a contribution helps the next module get written.
GitHub Sponsors
Sponsor on GitHub for a monthly amount (any value, set by you), or send a one-off contribution. Payments are processed by GitHub; no account beyond your existing GitHub one is required. Best signal of support for an open-source project.

For supporters who prefer not to use GitHub. Send any amount as a one-off contribution; the link goes to my personal PayPal.me page, which accepts cards and bank transfers in addition to PayPal balances.

For supporters who would rather contribute on-chain. Best suited to larger one-off contributions where a settlement delay and a small network fee don't matter. Smaller tips are more efficient via the Lightning option below.

Once the address is published here, this card will also expose a QR code on hover.
Bitcoin Lightning
Instant, fee-free (or near-fee-free) tips over the Lightning Network. Suited to small contributions — the equivalent of buying a coffee. Compatible with any Lightning wallet (Phoenix, Wallet of Satoshi, Strike, Cash App, Zeus, Alby, …).
[Lightning address (LNURL) coming soon]
A static Lightning address (e.g. kevin@…) avoids the per-payment invoice dance and lets supporters tip as easily as they send an email.
Other ways to help
- ✦ Tell people about it. If you teach with Empiria, mention it in a methods session, on social media, or in your syllabus. Word of mouth in the statistics-education and computational social-science communities beats any donation in long-run usefulness.
- ✦ Open issues on GitHub. Bug reports, edge cases, requests for new modules, and pedagogical feedback are all welcome at github.com/kevisc/empiria/issues.
- ✦ Cite the paper. If Empiria appears in published research or coursework materials, please cite the companion paper — see the Empiria page for the BibTeX block.
- ✦ Send a screenshot. If you've used a module in a teaching context and it landed, a two-line email about how it went is genuinely energizing. kevinschonholzer@gmail.com
