Has it gotten better and good enough? I tried it a few months back and it was pretty crappy. And it's not because of bad models (I used it with the latest Claude at that time) but because of poor harness implementation and UI.
Is it worth trying the latest version to see how it compares with Claude Code? I want OSS, model agnostic implementation to win but I felt the odds are off then. I'd be happy to be proven wrong.
Instead, its strength tends to be a continued improvement over the long term, in a way that commercial software just can't sustain because it needs to show a return on investment.
I use OpenCode as my main CLI tool at this point, falling back to Claude Code and Codex as needed. It's really solid these days, highly recommend.
I use Claude Sonnet 4.5, Gemini 3 Pro Preview, and GPT 5/5-mini with great results on OC. I initially tried it so I could decouple from VS Code extensions while still using my Github Copilot plan like I had been with Roo Code/Kilo Code, but have branched out to also using it with the Claude Code backend and their free models as they come and go.
Definitely worth trying if you haven't picked it up recently.
I did tried as well few months and also uninstalled. Application didn't at least back then have update feature and for each new release you had to reinstall again. UI experience was also very poor comparing to many other open source projects - would expect they at least hire some designer
Forgive me for underestimating but I'd never heard of 'Block' before, and the title "Block, Anthropic, and OpenAI Launch the Agentic AI Foundation" reads a bit funny to me. Plus the bitcoin blurb on their site is also worth a chuckle -
"Bitcoin is about access, not speculation. It’s designed to be open, fast, low-cost, and free from centralized control. It’s meant to empower people"

This is the most amazing paragraph I think I have ever read, pure gold!
So I'll focus on the block's contribtution, which is goose: https://github.com/block/goose

Open source rarely wins at the start.

The OpenHands CLI has had some major improvements since v1: https://github.com/OpenHands/OpenHands
MIT license and model agnostic
I’d also keep a close eye on Toad which is launching this month:

Tried Goose, couldn't do anything. OpenCode is better. Mistral's Vibe too.
Goose was super jank when I last tried it. Not worth a look

Block is the new name for Square, also of CashApp.
Yeah... Still gonna use my credit card or debit card.
That website reminds me of the one…where a guy sold pixels on a website for like a buck and people basically bought ads.
https://en.wikipedia.org/wiki/The_Million_Dollar_Homepage
The guy who created that page actually went on to found the Calm app, which has a multi billion dollar valuation now.
Yes it does feel a bit grift adjacent.
Spot the odd one out
Such irony given Anthropic is hostile to open sourcing their agent frameworks like clause desktop and CLI.
