Cubent
Agentic AI coding assistant for VS Code with BYOK multi-model access and local-first privacy.
Cubent delivers agentic coding with real model flexibility at a bargain price. The $5/mo BYOK plan is a no-risk entry, especially with GPT-5 and Claude 4.5 support. Teams needing SSO or centralized billing should wait for the Pro/Team tiers. For solo devs and small teams who value privacy and model choice, it's a smart Cursor alternative.

Skip Cubent if you need enterprise features like SSO or centralized billing that are still coming soon, or if you prefer a built-in credit model over managing your own API keys.
You need to bring your own API keys and pay for usage separately, so the $5/mo subscription is on top of your actual model costs.
Cubent's $5/mo BYOK plan is a low-cost entry for solo devs and small teams, cheaper than Cursor's $20/mo Pro and GitHub Copilot's $10/mo. However, you'll pay for API usage separately, so total cost depends on your model choices. Pro and Team tiers are coming, but enterprise features like SSO are only in the future Team plan.

Best for Solo developers building full-stack projects quickly, Engineering teams wanting consistent code review and documentation, Developers needing multi-language support in a single editor.

About Cubent
Cubent is an AI-powered coding assistant that works as an autonomous agent inside your editor. It handles real engineering tasks—generating code, hunting bugs, refactoring, documenting, and even opening pull requests—so you can focus on guiding and reviewing rather than typing everything yourself. Built for developers who want more than autocomplete, Cubent understands your entire codebase, including dependencies, structure, and deployment configs, and acts on that understanding with full transparency. What sets Cubent apart is its BYOK (bring your own key) flexibility. Instead of locking you into one provider, Cubent lets you connect to 23+ models from OpenAI, Anthropic, Google, Cohere, Mistral, and OpenRouter—so you control both cost and quality. Recent updates confirm support for GPT-5, GPT-5 mini, GPT-5 nano, Claude Opus 4.1, and Claude 4.5, making it one of the first tools to embrace the latest model releases. Cubent doesn't stop at code suggestions. Its Agent Mode autonomously executes multi-step tasks like writing tests or refactoring legacy modules, while Chat Mode offers conversational debugging and code generation. You also get terminal integration for running commands and analyzing output, live browser preview from chat, custom modes (e.g., a security auditor that found vulnerabilities one user says they missed), and screenshot analysis to catch UI issues before they ship. And it's all local-first—Cubent never trains on your code, keeping your projects yours. On pricing, Cubent offers a free 7-day trial of its Byok plan at $5/month, which includes unlimited messages and chat conversations, plus access to all 23+ models. Pro and Team tiers are coming soon, with options like Cubent Units (so you won't need your own API keys) and enterprise features like SSO. If you're a developer who values model choice and privacy, Cubent is a compelling alternative to Cursor or Copilot—though you'll need to manage your own keys on the base plan.
Behind the Verdict
Cubent stands out in the crowded AI coding assistant space by giving you full control over the models you use. With BYOK, you can plug in OpenAI, Anthropic, Google, Cohere, Mistral, or OpenRouter—23+ models total—and pick the best one for each task. The recent addition of GPT-5 and Claude 4.5 shows the team is quick to adopt new releases, which matters if you want cutting-edge coding help. The agentic capabilities are genuinely useful. Agent Mode can take a complex task like writing tests or refactoring a legacy module and execute it end-to-end, even opening a pull request. Chat Mode is solid for conversational debugging, and the custom modes let you tailor the assistant to your workflow—one user created a security auditor that found vulnerabilities they'd missed. The terminal integration and live browser preview are practical touches that reduce context switching. Where Cubent falters is in its maturity. It's in early access, and the Pro and Team tiers—which would add Cubent Units, SSO, and team features—are still 'Coming Soon.' The BYOK plan requires you to manage your own API keys and monitor usage costs, which can be a hassle. There are also open questions about usage limits and mixing built-in and BYOK models, so you'll need to plan around that. For solo developers and small teams who value privacy and model choice, Cubent is an excellent, low-cost option. It's not yet ready for large enterprises that need SSO, centralized billing, or guaranteed uptime. If you're comfortable with early-access quirks and bring-your-own-key, it's worth a try—the 7-day free trial lets you test it without commitment.
