Craft has project management and generates starter project structure. You can generate header and source files with boilerplate starter code. Craft manages the building of the project so you don’t need to write much CMake. You can also save project structures as templates and instantiate those templates in new projects ready to go.
I dislike how Zen (and many similar cases, not picking on Zen here) report being not for profit or transparent, while the auto-recharge mechanism guarantees they are sitting on a float of at least $5 per account, and presumably an average of at least $10. That's something like 50 cents of interest income per year per account. It's not nothing and it's hardly egregious fraud, but I feel if they will do this when it's obvious what they're doing, what other corners might they cut
Honesty as a marketing strategy is really undervalued in cases like this
I haven't tried $20 claude code recently, but I've used OpenCode Zen primarily so I can play with opensource/chinese models which are very inexpensive. I'd spend $0.50-$1.00 on a single claude opus 4.6 plan mode run, then have a chinese model execute the plan for like $0.10-$0.15 total. I'd keep context short, constantly start new threads, and get laser focused markdown plans and knowledgebase to be token efficient.
If I just let opencode zen run claude opus to plan and execute, I'd spend $20 in like 5 minutes lol
Whenever a new one comes out, there's a good chance they're free for a week on Zen, so I try out any free ones. For example, MiniMax M2.5 and Qwen 3.6+ are free right now.
Personally, I've had a lot of good results in my little personal projects with Kimi K2.5, GLM 5 and 5.1, and MiniMax M2.5.
I mostly use Opus via Copilot with opencode, and I'll tell you, in the past few days, I've had long sessions (almost the whole day) without hitting rate limits. That's very different from Claude Code, which used to rate-limit me before even halfway through the day.
