Top 3 right now

Few of them is my fav. for setup in 04.2026. After weeks of tests most 'optimus prime' setup for me: 

I. OpenCode (probably best alternative for Claude Code with open source)

II. HeStrike AI (it's like complex magical spell for real sorcerer's, still learning)

III. Nebula (Simple and OK in case of support when need more manul, evasion techniques)
