CodeGPT

CodeGPT is an AI coding assistant that lives inside VS Code, JetBrains IDEs, and Cursor as an extension rather than a standalone IDE. Its core differentiator is bring-your-own-key by default: you connect your own API keys from OpenAI, Anthropic, Google, Mistral, Cohere, Ollama, and 50+ other providers, so you control model choice, cost, and data routing with no platform markup on tokens. The free tier includes a daily allowance on its own Economy models plus BYOK across 15+ providers and local models.

Beyond chat and autocomplete, CodeGPT offers an agent mode with planning — it thinks through a problem, drafts a plan, then executes multi-step edits — plus MCP integration for pulling in docs, issue trackers, and database schemas as context. An enterprise tier supports self-hosting for privacy-sensitive teams. Limitations: the free Economy tier does not disclose which models it routes to, and there is no automatic codebase indexing (it relies on in-context file selection rather than Cursor-style background indexing).

Install the CodeGPT extension from the VS Code Marketplace or JetBrains Marketplace, create a free account at codegpt.co, and either use the daily Economy allowance or add your own provider API keys in settings.
