I know there are lots of analogues and people are used to it, but in each of them you can find the lack of something that you cannot fulfill by yourself.
Some of the services limit you with a small participants amount, some are only html-based and do not have a proper bracket export, some do not have a user-friendly mobile support, some are slow and overloaded with lots of unnecessary libraries or scripts and so on.
I have tried to solve all the things that are coming into mind and over the last year created a lightweight service https://tgrids.com - for now it supports Single and Double Elimination, but there are plans to add Round Robin, Swiss, probably some other competition types and useful features. It allows you to add up to 512 players, embed your brackets as svg or iframe and there are live updates on the website and in the iframe version.
The thing is that i would like to hear from the users what do they want exactly and try to fulfill as much needs as possible. Maybe there is a request of a customizable bracket format with your own colors and sizes? Maybe different tournament types? Maybe an API for other web developers?
Please let me know what you think, I would really appreciate any support and feedback.
