tc-lib-pdf, the legacy TCPDF (installed 100M+ times), and the wider tc-lib package stack are built and maintained by Nicola Asuni (Tecnick.com LTD). For over 25 years this has been free, open-source infrastructure that thousands of products and research pipelines depend on every day.
Sponsorship pays for the unglamorous half of that: security fixes, tracking standards revisions, and answering issues. If your company ships one of these packages, it is closer to an insurance premium than to a donation.
Why Sponsor
- Continuity and security of a PDF stack your products, or your dependencies, already rely on.
- Your logo on the Tecnick.com organization profile, in the README of the project you rely on, and on this website for the PDF stack.
- Priority issue triage at the higher tiers.
Sponsorship Tiers
The authoritative tiers are on the GitHub Sponsors page. README placement starts at Bronze ($100/month); logo placement starts at Silver ($250/month); everything below Bronze is listed in the backers list only.
| Tier | Price | What you get |
|---|---|---|
| Individual Backer | $5/mo | Name in the backers list |
| Supporter | $50/mo | Name and link in the backers list |
| Bronze | $100/mo | Supporter + name and link in the README of the project you rely on |
| Silver | $250/mo | Bronze + your logo in that README |
| Gold | $500/mo | Silver + larger logo; priority issue triage |
| Platinum | $1,000/mo | Gold + logo and link on the project website (or tecnick.com) |
| Strategic Partner | $2,500 or $5,000/mo | Platinum + top logo placement and release-notes mention |
| Coffee (one-time) | $25 / $50 / $100 | Name in the backers list |
Strategic Partner is offered as two fixed tiers ($2,500 and $5,000/mo) or a custom amount on the Sponsors page.
How to Become a Sponsor
- Go to github.com/sponsors/tecnickcom and choose a tier (or set a custom amount).
- For README placement (Bronze and above): after sponsoring, open an issue titled
Sponsor placement: <Company>(or email info@tecnick.com) with the destination URL and, for logo tiers (Silver and above), your logo as SVG (or high-resolution PNG with transparent background). Tell us which project you rely on so it lands in the right README. We add it once approved (see the policy below).
One-time contributions are also welcome via PayPal.
Sponsors and Backers
Sponsor logos appear on the Tecnick.com organization profile. The full backers list is maintained in BACKERS.md and kept up to date from GitHub Sponsors.
Platinum sponsors and Strategic Partners are featured on this website (tcpdf.org) for the PDF stack.
Logo and Content Policy
Payments cannot be pre-approved; anyone may sponsor through GitHub. Logo and link placement, however, is published at the maintainer’s discretion after review.
Logo and link placement is subject to maintainer approval. We may decline or remove any logo or link at our discretion, including content that is adult, gambling, illegal, malicious, or competing without disclosure. Declining placement does not entitle a refund of past contributions; you may cancel future sponsorship at any time.
Links placed on this website carry rel="sponsored nofollow".
