I'm surprised that people still aren't discussing Github Copilot baked into VSCode. I pair agent mode + Sonnet 4 + Sequential Thinking + Tavily MCP servers and it works wonders. I recently prototyped the first version of our SaaS with this setup in a minimal amount of time. Also worth nothing, the pricing is extremely reasonable. Free credits + pay per use. I frequently max out the free tier and have never spent more than $40 per month.
