Ada vs OpenCode
Both stand on ai code generators. Which one you can start free with, which one lets you read the code, and what each costs once you pay.
Free plan LinuxMacSelf-hosted+1
Ada combines a standalone editor with repository-aware agent tools, model choice, and in-editor Git actions. Note its beta access limit and that the Free plan uses your own key for paid models.

Choose OpenCode if you want an open-source coding agent across terminals, desktop apps, and listed editors, with broad model support. Look elsewhere if you need Windows use without WSL, or if the listed Go usage allowances do not suit your needs.
