GitHub Copilot Alternatives for VSCode

1/10/2026

• GitHub copilot with Claude Opus 4.5 is best for paid enterprise plans.
• Copilot with GPT 5 mini next best free, but rate limits.
• VSCode extension Continue with openrouter and model Grok 4.1 Fast next best as replacement for Copilot but costs $0.10/day and limited to trial of $1 before paying.
• VSCode extension Continue with openrouter and free model (Devstral 2 2512, Qwen3 Coder 480B A35B, gpt-oss-120b) may be next best.
• VSCode extension Continue with Ollama service running locally and llama-3.3-70b or codellama is not very good but free for local.

That’s why fs.writeFile can’t even create/open the file—it’s not a valid filename on your system (likely macOS or Linux).
