Loki4j is free, BSD-2 licensed, and maintained by one person outside of working hours. It's downloaded ~400,000 times a month and has shipped 40+ releases since 2020. Sponsorship is what keeps that going: compatibility with each new Loki release, security patches, bug fixes, and docs that stay accurate.
If your services run Loki4j in production, backing the project invests directly in its future. Company tier starts at $100/month, and comes with: your logo and link in the README, your logo and link on this site, your name in the notes of every release you help fund. If that sounds worth supporting, please follow the link below.
Send this to whoever owns your team's tooling budget:
We use Loki4j to ship logs from our Java services to Loki. It's a direct production dependency — if it stops being maintained, our observability pipeline is affected. It's open source, maintained by a single developer in their spare time, and downloaded ~357,000 times a month. Sponsorship starts at $100/month and funds compatibility with new Loki releases, security patches, and bug fixes. We'd also get our logo in the project README and docs. → https://loki4j.github.io/loki-logback-appender/supportus
Can we get an invoice?
Yes. GitHub Sponsors issues invoices for organization sponsors, so your finance team gets proper documentation for the payment.
Will our name and logo be added automatically?
No — nothing is published without your say. After you sponsor, you'll receive a welcome message containing an email address. Send the name or company name you'd like listed, a link if you want one, and a logo in SVG or PNG if your tier includes it. If you'd rather stay anonymous, just say so — or simply don't reply.
We can't approve a recurring subscription - is there another way?
There are one-time tiers alongside the monthly ones. A single payment often clears procurement far more easily than an ongoing commitment, and it carries the same recognition for twelve months.
I'm not a company - can I still help?
Yes, and not only with money. Sponsorship starts at $5/month, but a good bug report with a reproducer is worth just as much. So is answering a question in Discussions, fixing a typo in these docs, writing about your Loki setup, or simply telling your team that Loki4j exists. And if you'd like your employer to sponsor, the answer "How do I make the case at my company?" is written to be forwarded.
What does sponsorship not include?
Sponsorship is not a support contract. It doesn't come with response-time guarantees, private support, or committed feature work — it funds the ongoing health of the project, which benefits everyone using it. If you need contractual guarantees, get in touch and we can discuss it separately.
