52 reposThe default for Next.js builders in 2026. Not a dependency — you copy components into your codebase and own them forever. Built on Radix primitives so accessibility is solid out of the box. The catch:…
The safe enterprise pick. Massive component library, well-documented, every internal admin tool uses it. Price: your app will look like every other Material Design app, bundle sizes are heavy, and cus…
The accessibility primitives shadcn/ui is built on. If shadcn is too opinionated drop down one level and use these directly. WAI-ARIA compliant out of the box, unstyled so you bring your own design. ~…
New library from the MUI team in 2026, similar philosophy to Radix Primitives — unstyled accessible components. ~3.7M weekly downloads in early 2026 and moving fast. Worth watching if you hit Radix li…
Modern visual style, animations baked in, built on Tailwind. ~22k stars. Slightly more opinionated than shadcn but ships pre-styled. Recently rebranded — check the latest docs.
Unstyled, accessible components from the Tailwind team. Smaller surface than Radix but tighter integration with Tailwind ecosystem. Good for simple custom design systems where you do not need Radix-le…
The CSS framework that won. Utility-first, brutal on first sight, addictive after a week. ~83k stars. Pairs with literally every UI library that matters in 2026. Default expectation for new React/Vue/…
Theme tokens spec for React — colors, spacing, typography as a single config. Older but the underlying idea (design tokens) still matters. Worth knowing the pattern even if you build tokens yourself w…
5,000+ free MIT-licensed SVG icons. Wider coverage than Lucide for niche concepts. ~19k stars. Active maintenance, frequent releases.
The industry standard for advanced web animation since forever. Framework-agnostic — works with React, Vue, vanilla JS, anywhere. Strongest tool for complex timelines, scroll-driven animation, and SVG…
Physics-based spring animations for React. ~29k stars. Better than Motion when you need genuinely physical motion (interruptible drags, momentum scrolls). Less DX polish than Motion for the common cas…
Render Adobe After Effects animations as JSON in the browser. ~30k stars. Best way to bring a designer's After Effects work to web/mobile without re-implementing. Files can be large — optimize them.
50+ animated React components built on Motion + Tailwind. Copy-paste style like shadcn but for animated effects: animated text, marquee, bento grids, file trees. Pairs perfectly with shadcn for landin…
Premium-feeling animated components for landing pages. Free core + paid pro. Useful as a reference even if you do not use the components directly — the source shows good Motion patterns.
The biggest LLM framework. Chains, agents, RAG pipelines, integrations with every model, vector DB, and tool. Strong ecosystem with LangGraph for agentic workflows. The criticism: for simple use cases…
RAG specialist. Better document loading, chunking, and retrieval than LangChain for retrieval-first apps. Strong on advanced strategies — hybrid search, re-ranking, recursive retrieval. Now expanded i…
Multi-agent conversation framework from Microsoft. Stronger than LangChain for genuinely autonomous multi-agent setups where agents negotiate with each other. Younger ecosystem, fewer integrations.
Role-based agent orchestration. Simpler mental model than AutoGen — define agents with roles, give them tools, let them collaborate. Popular for content workflows, research agents, and internal automa…
Rust-based vector database — fast, production-grade, Apache 2.0. Good developer experience and clear pricing if you use their managed cloud. Strong choice if Postgres+pgvector cannot handle your scale…
AI-native embedding database designed for rapid prototyping. Easy to run locally, tight LangChain integration. Better for hackathons and internal tools than huge production deployments.…
Vector search inside Postgres. ~12k stars and dominant in 2026 as the boring-but-correct default. If you already have Postgres (Supabase, Neon, RDS), do not add another database — just install this ex…
Open-source vector DB with the most mature features for huge scale. ~30k stars. Steeper operational burden than Qdrant. Used in production by companies doing serious vector workloads.…
Vector DB with strong hybrid search (vector + keyword) and built-in modules for common embedding workflows. Slightly higher learning curve than Qdrant but powerful for production RAG.…
Run open-source LLMs locally with one command. ~95k stars. Essential for AI development — test prompts against Llama, Mistral, Phi without burning API credits. Production use is limited unless you hav…
The OG Next.js auth library, now Auth.js. ~24k stars. Quick to add OAuth providers (80+ preconfigured). Best for fast MVP work where you mostly need social login. Less flexible than Better Auth for ad…
Note: Lucia announced deprecation in 2024 — the maintainer is sunsetting it in favor of writing your own. Still useful as a learning reference for session-based auth patterns in TypeScript. Better Aut…
Enterprise auth/IAM platform. ~24k stars. Java-based, self-hosted, supports SAML, OIDC, fine-grained authorization. Heavy to operate but the right pick for compliance-heavy enterprise apps.…
Postgres + Auth + Storage + Realtime + Edge Functions in one open-source platform. ~73k stars. The fastest way to ship a backend in 2026 for solo founders and small teams. Mumbai region for India late…
Single-file Go backend with SQLite, auth, file storage, realtime. ~40k stars. Pocket-sized Supabase alternative. Great for indie projects, prototypes, and self-hosted internal tools.…
The fastest, smallest form library for React. ~39k stars. Uncontrolled by default so re-renders stay minimal. Pairs naturally with Zod for validation. Default choice for any React form heavier than a …
Form state library, framework-agnostic. React Final Form was popular pre-React Hook Form. Less active today.…
Atomic state for React. Different model than Zustand — composable atoms instead of a single store. Better for derived state that updates granularly without re-renders.…
Actor-based state machines. ~27k stars. Overkill for most apps but unbeatable for genuinely complex workflows — multi-step forms, async retries with rollback, real-time collaboration. Worth learning e…
Observable-based reactive state. Different mental model than Zustand/Jotai — closer to Vue's reactivity. Still active but losing ground to simpler stores in 2026.…
The React framework. ~128k stars. App Router is the bet — server components, server actions, edge runtime. 2026 sentiment is mixed: people love the capabilities, complain about the complexity. Still t…
Svelte's Next.js. ~19k stars. Smaller community than React but the DX is genuinely better and runtime bundles are smaller. Worth considering for greenfield projects where team training is feasible.…
JSX with fine-grained reactivity instead of VDOM. ~33k stars. Closer to Svelte's mental model with React's syntax. Smaller community but excellent performance.…
Tailwind for React Native. Compiles utility classes at build time. Best when you already love Tailwind on web and want the same workflow on mobile.…
New 2026 entry from TanStack — local-first reactive DB for offline-capable apps. Worth watching but ecosystem is still young.…
Open-source product analytics. ~21k stars. Self-hostable or managed. Combines analytics, session replay, feature flags, A/B testing in one platform. Generous free tier — most early-stage products neve…
Full-text and vector search engine that runs everywhere — browser, edge, server. Useful for client-side search on small datasets (docs, blogs) where you avoid backend round-trips.…
React components for email. Build emails as React, render to HTML for sending. Pairs with Resend's sending API for the cleanest email DX in 2026. Free up to 100 emails/day on Resend.…
Tailwind for email. Authors HTML emails using Tailwind classes, compiles to inlined CSS for email clients. Smaller community than React Email but battle-tested for client compatibility.…
Component development environment. ~84k stars. Develop, test, and document components in isolation. Mostly used by larger teams with design systems.…
Define multi-container apps in a single YAML file. Still the simplest way to run a local dev environment with multiple services (DB, cache, app, worker).…
Self-hosted PaaS. ~13k stars. Similar pitch to Coolify, slightly older. Both work — pick the docs you find clearer.…
The 2026 default for LLM-grade scraping. Fires Playwright behind the scenes, returns clean markdown ready to feed into RAG. Self-host for free or use the hosted tier — both expose the same API. The sw…
Python-native LLM-friendly crawler. Strong at extracting structured data (JSON schemas) from messy HTML using an embedded LLM. Heavier setup than Firecrawl but more control over extraction prompts. Be…
Node-native crawler from the Apify team. Built-in queues, retries, proxy rotation, headless browser pool — production patterns out of the box. Switches between Playwright, Puppeteer, and plain HTTP ba…
The browser automation library the rest of the scraping tools depend on. Direct API for when you want fine-grained control: stealth mode, anti-bot bypass, multi-context, headless or headed. Also doubl…
jQuery-style HTML parsing for Node, with no browser. Ridiculously fast because it never renders JS. The default when you're scraping server-rendered pages (most blogs, docs, news, marketplace listings…
Go's answer to Scrapy. Built-in rate limiting, caching, parallelism, and storage backends. Compiles to a single binary which makes deployment to a cheap VPS trivial. Use when you want to scrape millio…
