Opposable vs Staffcoder, hands-on practice for modern frameworks in a browser IDE

Opposable is computer use for phones. Claude Code, Codex or an on-device model can see, tap and type across every app on a real Android phone, yours or one in our cloud. hey! we built Opposable (named because it gives your AI thumbs to use a smartphone) to bring the computer use revolution to smartphones in a easy-to-use and not too hacky way. most of our life is already on our phones, this enables you to do a lot of things while the phone is in your back pocket.some things /are/ hacks, like using a flashable bluetooth dongle to play as a keyboard+mouse to control iPhones.. but it works!

Staffcoder helps developers build real-world engineering skills through hands-on framework practice and production-style challenges in a professional IDE. Hi HN,I'm Shashank. I have curated 1000s of practical real world software engineering assessments in the past as part of my job. I felt there's a gap where if a person wants to learn to build software they have many options to learn from (learning platforms and free resources) but very few or no options to practice their skills hands on. I built Staffcoder so that developers can learn the skills while solving real world scenarios across various domains in software engineering.On Staffcoder you can select a skill, start from beginner level and move up solving real world challenges.
