Continue is an open-source IDE extension that brings AI coding assistance to VS Code and JetBrains without locking you into a specific model or provider. You can connect it to OpenAI, Anthropic, local models via Ollama, or any OpenAI-compatible API. The custom context providers let you pull in documentation, Jira tickets, or any other source.

Pricing: Free (open source, BYOK)

SWE-agent, from Princeton University, is an open-source coding agent designed specifically for software engineering tasks like fixing bugs and implementing features from GitHub issues. It uses a custom agent-computer interface to interact with code repositories. It consistently ranks near the top of the SWE-bench benchmark for resolving real-world coding tasks.

Replit Agent goes from a plain-English description to a live, deployed application. It builds the full stack, runs tests, and gives you a URL within minutes. The 30+ native integrations (Stripe, Figma, Notion, Salesforce) mean the agent can wire up real services without manual configuration. Best for rapid prototyping and non-developers getting started.
