What Tech Stack Would We Use for B2B SaaS in 2026? | Into the Gnar EP.3

Not sure if your team is actually ready for AI? We built a free 2-minute assessment that gives you a straight answer → ai-assessment.thegnar.com/ If your team is about to pick a tech stack and nobody can agree on what to build on, this one's for you. We've been getting this question constantly since the AI coding wave hit. If you were starting a B2B SaaS company today, what would you actually build on? Not what sounds impressive. Not what worked five years ago. What would you ship on right now. This week we talk about why the tool is almost never the problem, why boring technology is still the right call in 2026, and why the LLM your team codes with is starting to matter as much as the framework you pick. We also get into something founders don't talk about enough: the difference between a tech stack that gets you to launch and a stack that quietly kills you six months later. We cover the AI coding tool wars — Claude Code, Cursor, Copilot, Codex — and what the data actually says about who's winning and why. Spoiler: developers find the better tool. They always do. Here's what we got into: The worst B2B SaaS tech stack decision we've ever seen and what it actually cost Why 84% of developers use AI coding tools daily but only 29% trust what ships to production Claude Code vs. Copilot vs. Cursor in 2026 — what we actually use and why The exact tech stack we'd choose to build a B2B SaaS startup today Why annual AI tool licenses are a trap and what to do instead What "AI-ready architecture" actually means in practice If you're sitting on a stack decision right now, or someone on your team is pushing for the shiny new framework, send this one to your CTO before your next architecture conversation.
