Good specialized service +4

Pros

  • Single OpenAI-compatible endpoint routing to models from OpenAI, Anthropic Claude, Google Gemini, and DeepSeek
  • Seamless compatibility with AI coding environments and terminal agents including Cursor, Claude Code, Cline, and Codex CLI
  • Pay-as-you-go billing with formal contracts and electronic document exchange (EDO) for legal entities
  • Transit-only request routing combined with automated PII masking for sensitive information

Cons

  • Pre-request balance holds can trigger insufficient funds errors if output token limits are left undefined
  • Reasoning models can exhaust restrictive token limits during internal thinking steps, returning blank responses
  • Deposited account funds cannot be refunded or withdrawn back

Good product +2

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
