Blackbox
Blackbox puts inline completions, chat-driven edits, and parallel agent runs inside VS Code, JetBrains, a standalone IDE, CLI, mobile apps, and a web builder. One account spans Blackbox, Claude Code, Codex, and Gemini, so you can compare multiple implementations before merging a diff. The VS Code extension has 4.2 million installs and supports TypeScript, Python, Go, Rust, Java, and C++.
Most coding assistants pick one model and hope for the best. Blackbox routes the same task to multiple agents, then its Chairman LLM scores each output and surfaces the winner as a reviewable diff. That multi-harness approach shows up in pricing too: Pro starts at $10 per month with included model credits, while Pro Plus adds multi-agent execution, a 35+ IDE coding agent, and Slack integration at $20 per month.
Individual developers use the free tier for inline completions on Minimax-M2.5. Teams on Pro Max get SAML SSO, centralized billing, and usage analytics. Enterprise customers can deploy on-premise with training opt-out by default and custom SLAs.
