The modern web stack, mapped
Choosing a tech stack in 2026 means wading through hundreds of frameworks, databases, hosts, and hype cycles. newstack.dev cuts through it with opinionated guides, a curated tool directory, practical cheatsheets, honest head-to-head comparisons, frontend decision guides and launch checklists, DevOps playbooks, and a clear-eyed look at AI coding assistants - so you can pick your stack with confidence and get back to building.
Seven ways to decide faster
Stack Guides
Recommended stacks for SaaS, static sites, APIs, AI apps, ecommerce, mobile, desktop, CLI tools, browser extensions, realtime apps, internal tools, and weekend MVPs - with the reasoning behind every pick.
Browse guidesTool Directory
The modern stack organized by layer: frontend, backend, databases, hosting, auth, CSS, testing, ORMs, AI, monitoring, CMS, and email. Curated, not exhaustive.
Explore toolsCheatsheets
Quick references for the tools you touch every day - Git, Docker, SQL, TypeScript, React hooks, Tailwind, regex, and more. Bookmark and return.
Grab a cheatsheetComparisons
Next.js vs Astro. Postgres vs SQLite. Bun vs Node.js. Head-to-head breakdowns that open with a verdict instead of burying it.

How to choose a framework, rendering model, component library and state layer - then the launch checklists that catch what a code review misses.
Build the frontendDevOps
CI/CD pipelines, containers, infrastructure as code, and self-hosting - the ship-it side of the stack, with its own cheatsheets and verdicts.
Ship with confidenceAI Coding Tools
Claude Code, Cursor, Copilot, and Codex - which assistants actually help you build, how to work with them, and what MCP really is.
Code with AIOpinionated on purpose
Most stack advice hedges: "it depends" helps nobody who has to ship. Every guide and comparison here commits to a recommendation, states the tradeoffs plainly, and tells you when the runner-up is the better fit. When the honest answer changes - and in this industry it does - the pages change with it.
Recommendations favor boring-but-proven defaults, generous free tiers, and tools you can leave behind without a rewrite. No sponsorships, no affiliate links, no pay-to-play rankings.
