Continue.dev vs Google AntiGravity

Open source vs closed. Continue.dev is Apache 2.0 licensed. You can read the code, fork it, self-host it, contribute to it. Antigravity is proprietary. You get what Google ships. For teams with security requirements or developers who care about transparency, this is a big deal.

Extension vs full IDE. Continue.dev lives inside your existing editor. You keep your VS Code config, your keybindings, your extensions, your JetBrains setup. Antigravity replaces your editor entirely. It's a VS Code fork, so it feels familiar, but it's a separate application. Your VS Code extensions might work, or they might not.

Model freedom. This is where Continue.dev pulls ahead for power users. You can run any model: local Ollama with Llama, DeepSeek, or Mistral for completely free and private coding. Or connect to OpenAI, Anthropic, Google, Cohere, or any OpenAI-compatible API. You can even run different models for different tasks (fast model for autocomplete, strong model for chat). Antigravity gives you Gemini, Claude, and GPT. That's a solid lineup, but you can't bring your own keys or run anything locally.

JetBrains support. Continue.dev works with IntelliJ, PyCharm, WebStorm, and the rest of the JetBrains family. Antigravity doesn't. If you're a JetBrains user, this comparison is already over.

Agent architecture. Antigravity's multi-agent system is more sophisticated. It runs Manager and Editor agents in parallel, and those agents can control a browser alongside the editor and terminal. Continue.dev has an agent mode that handles multi-step tasks, plus PR quality checks that run as GitHub status checks. It's capable but more focused on code-specific workflows rather than cross-surface orchestration.

Vendor lock-in. Continue.dev has zero lock-in. Switch models, switch IDEs, self-host the backend. Everything you build with it stays portable. Antigravity locks you into Google's IDE, Google's model selection, and Google's pricing tiers.

Continue.dev and Google Antigravity both give you AI-powered coding, but their philosophies are opposites. Continue.dev is an open-source extension that plugs into your existing IDE (VS Code or JetBrains). You bring your own models: local Ollama for free and private, or any cloud API. It doesn't try to replace your editor; it enhances it.

Antigravity IS the editor. It's Google's full desktop IDE (a VS Code fork) with multi-agent orchestration built in. You download it, open it, and start coding with Gemini, Claude, and GPT models pre-configured. No API keys needed on the free tier. It's opinionated about the experience: everything happens inside their app.

The trade-off is clear: Continue.dev gives you freedom (any model, any IDE, open source). Antigravity gives you polish (zero setup, multi-agent, unlimited completions). If you value control over your toolchain, Continue.dev is the obvious pick. If you want everything working out of the box with no configuration, Antigravity gets you there faster.

Continue.dev's pricing is hard to beat. The open-source core is completely free when you run local models through Ollama or LM Studio. No rate limits, no weekly caps, no credit card. You're running inference on your own hardware. If you want cloud models without managing API keys, Continue Starter runs $3 per million tokens. Teams get centralized config and admin controls at $20/seat/month.

Antigravity's free Individual plan is generous: unlimited tab completions, access to all models (Gemini, Claude, GPT), and weekly rate-limited agent/chat usage. No credit card required. AI Pro at $20/month bumps those weekly limits higher. Ultra at $250/month gets you dedicated capacity. Credit packs ($25 for 2,500 credits) let you overflow when you hit limits.

For developers who run local models, Continue.dev costs literally nothing. Antigravity's free tier is genuinely useful for light to moderate use, but power users will hit those weekly rate limits. If you're writing code all day, you'll either need to pay for AI Pro or deal with throttling.

The value proposition splits cleanly: Continue.dev rewards technical investment (setting up local models, managing API keys) with no ongoing cost. Antigravity rewards convenience (zero config) but charges for heavy use.

If you care about privacy and want to run models locally: Continue.dev. It's the only option here that lets you run inference entirely on your machine. Nothing leaves your network.

If you want zero-setup AI coding with the latest models: Antigravity. Download it, open a project, start coding. No API keys, no model configuration, no provider setup.

If you use JetBrains: Continue.dev. It's the only one that works with IntelliJ, PyCharm, and the rest of the family. Antigravity is VS Code-only.

If you want multi-agent orchestration and browser control: Antigravity. Its Manager/Editor agent split with browser integration is more capable for cross-surface workflows.

If you want to avoid vendor lock-in: Continue.dev. Open source, model-agnostic, works with multiple IDEs. Nothing ties you to a single vendor.

If you're on a tight budget: Continue.dev with local models is completely free. Antigravity's free tier is solid but rate-limited.
