Google Antigravity Pros
- Parallel agent orchestration allows background subagents to work on backend logic, frontend code, and test suites simultaneously
- Browser-in-the-loop automation enables agents to launch local servers, test user interfaces, and inspect console logs autonomously
- Interactive Artifacts replace messy execution logs with structured diffs, checklists, and visual verification steps
- Flexible model choices across Google Gemini, Anthropic Claude, and open-weight architectures
Cons
- Noticeable integration friction and re-authentication issues when working inside WSL environments on Windows
- Intensive agent sessions quickly consume gigabytes of local storage with cache files and session databases
- Variable compute quotas can restrict deep reasoning depth during long, complex codebase refactoring runs
OpenCode Strong technology platform +4 Pros
- Fully open-source platform with a strict local-first, zero-retention privacy architecture
- Real-time LSP diagnostics catch type errors and broken imports during code generation
- Dual Plan and Build modes prevent unprompted or destructive edits to repository files
- Wide model compatibility covering major providers, local setups, and existing subscriptions
Cons
- Requires Windows Subsystem for Linux (WSL) for a stable terminal and tooling workflow on Windows
- Configuring multiple external API providers and tool permissions demands baseline developer familiarity
- Session sharing publishes conversations to web edge CDNs unless explicitly disabled in organization settings
