## How each alternative compares with Blackbox AI

- **Claude Code** (Paid, $20/mo, checked 2026-11-12): Sold per seat from $20 a month (Max $100, Ultra $200) and limited to Claude models, whereas Blackbox lists 300+ models on one endpoint and sells only a custom annual commit. Switch if you are one developer or a small team that wants a published $20 monthly price instead of a sales-led contract. Stay with Blackbox AI if your security review needs single-tenant deployment, data residency, customer-managed keys or zero data retention in a contract.
- **GitHub Copilot** (Free plan + paid, $10/mo, checked 2026-11-12): Priced per user at $10 (Pro), $39 (Pro+) and $100 (Max), each with monthly credits ($15, $70, $200); Blackbox bills only per token with no seat fee. Switch if you want per-seat billing with a free tier and agent help inside VS Code, JetBrains or github.com. Stay with Blackbox AI if you prefer one token-metered bill across 300+ models and no per-seat charge.
- **Cursor** (Free plan + paid, $30/mo, checked 2026-11-12): A full editor with cloud agents; Premium at $30 includes third-party models at API list price, while Plus at $8 allows only Grok models. Blackbox ships a CLI and APIs, not an editor. Switch if you want an editor with inline edits and cloud agents on a flat monthly plan. Stay with Blackbox AI if you drive agents from a CLI or an API and want model routing, failover and caching behind one endpoint.
- **OpenAI Codex** (Free plan + paid, $20/mo, checked 2026-11-12): Bundled in ChatGPT plans (Go $8, Plus $20, Pro from $100) and also available on an API key at pay-as-you-go rates, but cloud features need a ChatGPT sign-in. Switch if you already pay for ChatGPT and want a coding agent in the CLI, IDE, web and iOS for that price. Stay with Blackbox AI if you want Claude, Gemini, Codex and other agents run side by side through one orchestration layer.
- **Together AI** (Paid, Not checked): Publishes per-million-token rates openly (Qwen3.8 Flash $0.15 input, $0.47 output) and fine-tuning from $0.34 per million tokens; Blackbox quotes contracts against its own rate list. Switch if you want to call open models by API or fine-tune them without a sales call or annual commit. Stay with Blackbox AI if you need Blackbox's coding CLI and cloud coding agents on top of the routing layer.
- **Gemini CLI** (Open source, Free (self-hosted)): A Google sign-in gives 60 requests per minute and 1,000 requests per day at no charge; Blackbox's pricing page lists no free plan. Switch if you want a free terminal agent and accept Gemini models for the first 1,000 daily requests. Stay with Blackbox AI if you need models from several vendors, with routing and failover, behind a single contract.
- **OpenCode** (Open source, $10/mo (hosted), checked 2026-11-12): MIT-licensed agent with desktop, terminal and mobile apps; OpenCode Go starts at $10 a month and free models need no account, versus Blackbox's enterprise-only contract. Switch if you want an open agent with free models and a $10 monthly curated-model plan. Stay with Blackbox AI if you want cloud sandboxes, an Agents API and dedicated runners that a vendor operates for you.
- **Cline** (Open source, Free (self-hosted)): Plan and Act modes, MCP integration and an npm SDK (@cline/sdk) let you embed the agent in your own apps, with the model endpoint of your choice. Switch if you want an Apache-2.0 agent inside your editor that uses your own API keys. Stay with Blackbox AI if you want one vendor to supply routing, encryption and agents instead of wiring keys yourself.
- **Kilo Code** (Open source, Free (self-hosted)): MIT-licensed agent with a Slack integration and mobile app; the page claims 500+ models at cost and a no-credit-card free auto model. Switch if you want a Slack-triggered cloud agent and a free model option with no card. Stay with Blackbox AI if your contract requires single-tenant deployment and a dedicated forward-deployed engineer.
- **Qwen Code** (Open source, Free (self-hosted)): Apache-2.0 terminal agent that talks to OpenAI, Anthropic, Gemini and Qwen APIs or local Ollama and vLLM models; Blackbox's pricing page lists qwen3.8-max at $2.00 input, $6.00 output. Switch if you want an Apache-2.0 agent aimed at Qwen models and local runtimes. Stay with Blackbox AI if you want encrypted routing across 300+ models with spend alerts on a committed balance.
