Continue.dev

An open-source AI code assistant that runs locally inside VS Code and JetBrains IDEs, built by a community of developers who wanted Copilot without the vendor lock-in.

The problem it set out to solve

GitHub Copilot was fast and convenient, but it meant sending your code to OpenAI’s servers—a non-starter for teams with IP concerns, compliance requirements, or simply the desire to own their tooling. Meanwhile, local inference had gotten good enough to run on developer machines, but there was no seamless way to wire it into the IDEs people actually use. The gap between “I can run models locally” and “I can use local models as a real coding assistant” was still too wide.

The key insight

Rather than building a monolithic product, Continue treats itself as a bridge—a protocol-agnostic IDE extension that can connect to any inference backend: local llama.cpp, remote vLLM, Ollama, or even commercial APIs if you want. The builders understood that developers care less about a specific model or server and more about having control over where their code goes and which backend powers their completions. This inversion—let the user choose the engine—made the tool genuinely portable and future-proof.

How it works (in plain terms)

Continue is an IDE extension paired with a lightweight protocol for requesting completions and edits. You point it at any inference server that speaks the right interface—local or remote—and it handles the IDE integration: context window management, syntax highlighting, accepting/rejecting suggestions. The extension stays thin; the heavy lifting (model selection, serving, optimization) belongs to whatever backend you wire it to. You can swap from Ollama to vLLM to a custom inference pipeline without touching the IDE layer. The trade-off: you manage your own infrastructure, but you get total control.

What it looks like in practice

# In VS Code: Ctrl+K to open Continue's edit dialog
# Continue reads your open files, your cursor position, sends to local backend

# Your ~/.continue/config.json points to a local server:
{
  "models": [
    {
      "title": "Local Llama",
      "provider": "ollama",
      "model": "llama2:7b"
    }
  ],
  "tabAutocompleteModel": "Local Llama"
}

# Type a comment, hit Tab for completion. Continue sends request to your server,
# gets back tokens, streams them into the editor.

Why it matters

  • Ownership and compliance: Code never leaves your network unless you explicitly route it there. Critical for enterprises with data sensitivity or regulatory requirements.
  • Vendor independence: You can experiment with different models and inference engines without rewriting integrations. As the local model ecosystem evolves, your IDE setup adapts automatically.
  • Offline-first workflow: Your code assistant works in airplane mode, on weak wifi, or on an air-gapped network. You’re not hostage to API availability or rate limits.
