Monstera is free to use, but building and maintaining professional software isn't free. If you find it useful, your voluntary donation helps keep Monstera free for everyone.
Donations are processed by Stripe on its own secure payment page. You can make a one-time donation of any amount or a recurring donation to support our work. Every donation is appreciated.
Donations are optional and do not unlock additional features. They are generally non-refundable, except where required by law or payment provider policies. Tenslor Inc. is a for-profit company, not a registered charity, so donations are not considered tax-deductible charitable gifts.
Every donation helps keep development moving, the software maintained, and Monstera available to everyone without subscriptions, advertising, or paid features. These are some of the costs your donations help cover.
While we aim to provide Monstera as a free software, it still depends on real infrastructure. Development, testing, code hosting, build systems, certificates, publishing, security tools, and other services all have ongoing costs. Your donation helps keep the machinery behind Monstera running.
We constantly work to improve Monstera. New features take time. Bugs need investigation. Every release needs testing across real documents and Windows systems. Your support gives developers the time and resources needed to keep improving the software.
Even great software fails if no one can figure out how to use it. We write the guides, answer support questions, and keep improving accessibility so Monstera works for everyone. Your support helps us keep explaining, helping, and listening as Monstera grows.
We patch security issues, keep dependencies updated, handle licensing and legal paperwork, and watch for scam sites and fake clones trying to ride on the Monstera name. Your support helps us keep doing the unglamorous work that keeps Monstera safe to use.
Let's make Monstera a household name. Below are some ways you can help!
