Plasmo massively simplified the browser extension creation experience by offering SDK tools that streamline the development process. With Plasmo, I could write React code within relevant folders (e.g., content scripts under contents/, background scripts under background/), eliminating the traditional complexities of configuring and managing various extension components manually. The product's Itero platform is excellent in sharing the product during development for feedback, by publishing it on-the-go, including any new changes, in seconds.

We recently wrote a browser extension[1] without any prior experience, and Plasmo made it a breeze. Right from the start, we could focus on what we wanted to build, and not worry about the messy details involved in building a cross-browser extension. It just felt like writing a normal React app. Their documentation is also amazing. Can't recommend them enough. If you want to build a browser extension yourself, absolutely give Plasmo a try!

Plasmo's browser extension framework saved us months of development time with its streamlined workflows and modern tooling. We chose it over alternatives for its excellent TypeScript support, hot reloading during development, and simplified cross-browser compatibility. The framework made packaging for both Chrome and Firefox straightforward with minimal configuration.

I have to say that Plasmo has been a game-changer for me! As someone who is not an expert in building browser extensions, I was struggling to create my very first own extension. But with Plasmo, I found the perfect abstraction layer that let me start building with ease so I could focus on what matters most, the product. Using the Plasmo framework, I created Synclify, a free open-source extension that allows two people to sync their video playback by sharing a room code. This was a project that I had wanted to work on for a while, but I didn't know how to get started. Plasmo made it easy for me to get started and bring my idea to life. Overall, I highly recommend Plasmo to anyone who wants to create their own browser extensions but doesn't know where to start. The framework is user-friendly, and the support from the Plasmo team on Discord is fantastic. If you want to create a browser extension, try Plasmo – you won't be disappointed!

The plasmo framework itself is truly incredible a work of art and has helped me so much in my life, can't wait to see where it goes!! I love the vibe and energy in the community and it's just awesome how far it has already taken chrome extensions but also how much excitement there is to take it even further. I have been wondering about a future where plasmo turns the background.ts script of it's extensions into a fully fledged server that sends react ssg components to the frontend.

I used Plasmo to make my first ever chrome extension. It made it a breeze to do despite me not having any prior experience developing chrome extensions. I wrote more about it here -> https://words.byvernacchia.com/b... In addition to Plasmo itself and the nice docs, they provide great support on Discord!

Before I found plasmo, developing chrome extensions was tedious. Now, after building in it, i know it's the only good way to make a chrome extension. Great to see the official launch!

Maybe good framework, but there is no support. We needed a change on our Invoice. They never reacted.

This look promising but so far I am facing issues with its dependancies. I believe other Windows user might also facing issues with Sharp installation.
