Tuna

Tuna is open source software that allows companies to easily integrate with many different payment providers. The job it does: accepting cards, bank transfers and wallets online or in person.

Who is it for? Mostly any business that takes money. They also list Payments, so expect those to show up in the feature set. They are a small team, 11 to 50 people, which usually shapes who they work with. Small vendors mean quick answers and real influence on the roadmap, but check who covers support when someone is out.

Tuna is based in Dover, Delaware. Their site is tuna.uy.

Things worth asking about: rates, payout timing, chargeback handling, and developer tools. A short pilot with your real data tells you more than any demo.
