— the ones we'd ship with tomorrow
The 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 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. ~…
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/…
The full list
108 repos
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…
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…
Composable component library with strong defaults and a great theming system. ~38k stars. Sits between Material UI (too opinionated) and shadcn (too DIY). Good developer experience and accessibility —…
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.
100+ components and 50+ hooks. ~26k stars. Particularly strong on form handling and date pickers. Less hyped than shadcn but mature, well-documented, and just works. Good fit for SaaS dashboards.
The B2B default in Asia. ~93k stars. Deep, enterprise-grade component set — tables, forms, dates, charts all included. Visually distinctive (and dated to some eyes). Strong choice for admin panels but…
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…
ByteDance enterprise design system. Cleaner aesthetics than Ant Design, deep component library, growing presence outside China. Solid pick for enterprise tooling where you want a more modern visual ba…
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…
The icon set shadcn ships with. Clean, consistent stroke, ~1,400 icons, MIT licensed. ~13k stars. Better designed than Feather (which it forked from), better licensed than Heroicons in some setups.
5,000+ free MIT-licensed SVG icons. Wider coverage than Lucide for niche concepts. ~19k stars. Active maintenance, frequent releases.
Distinctive icon set with six weight variants (thin to fill). Best when your brand has a strong visual identity and the default Lucide aesthetic feels too generic.
Formerly Framer Motion. The default React animation library in 2026. Declarative, gesture support, layout animations, scroll, presence. ~31k stars and 3.6M weekly downloads. Trusted by Framer and Figm…
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…
Lightweight JavaScript animation engine. ~66k stars. Great for SVG and DOM animation without React-specific bindings. Smaller community than GSAP, but the API is approachable and the bundle is tiny.
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.
Motion graphics for the web — built for animated UI flourishes. Smaller community than Motion or GSAP but produces distinctive, polished microinteractions out of the box.
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 most flexible modern auth library for TypeScript stacks in 2026. Plugin ecosystem for 2FA, phone OTP, organization roles, audit logs. Same code works with Next.js, TanStack Start, Express. Becomin…
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…
Self-hostable auth backend with managed cloud option. Full session management, user management dashboard, multi-tenancy. Good middle ground between rolling your own and using a SaaS like Auth0.…
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…
TypeScript-first ORM with SQL-like syntax. ~25k stars. Lighter than Prisma, zero codegen step, faster cold starts on serverless. Becoming the default for new Next.js + Postgres projects.…
The polished ORM. ~38k stars. Best developer experience for relational data, declarative schema, generated client. Trade-off: cold starts on serverless are slower than Drizzle, and the abstraction can…
Decorator-based ORM, used heavily in NestJS ecosystem. Battle-tested but development pace has slowed. Drizzle and Prisma are the newer defaults for greenfield projects.…
Serverless-first MySQL client. Good when you are on PlanetScale specifically. Works well with Drizzle as the driver.…
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.…
Type-safe SQL query builder for TypeScript. Lower level than Drizzle/Prisma — closer to writing raw SQL with types. Best when you really want to think in SQL.…
Graph-relational database with EdgeQL. Beautiful query language, strong types, very opinionated. Smaller ecosystem so harder to hire for.…
The Indian payment stack. UPI, cards, wallets, EMI, subscriptions. INR-native so you avoid currency-conversion headaches. Mandatory if you are charging Indian customers. Better domestic rates than Str…
The global payment standard. ~3.9k stars on the Node SDK. Best developer experience in the industry. India support exists but pricing and onboarding are weaker than Razorpay for INR collection.…
Open-source billing/metering for usage-based pricing. Self-hostable or managed. Lighter than Stripe Billing for pure metering use cases.…
Open-source headless commerce. ~25k stars. Strong alternative to Shopify for teams that want full control over their commerce backend. Solid plugin ecosystem.…
TypeScript-first schema validation. ~35k stars. The de facto choice for input validation in TS apps. Works with every form library, every API framework, every ORM. If you are not using it yet, you sho…
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 …
New TanStack entry, framework-agnostic forms. Headless, type-safe, supports React/Vue/Solid. Worth watching but React Hook Form is more mature today.…
Schema validation predating Zod. Still works fine but Zod has better TypeScript inference. New projects should pick Zod.…
Form state library, framework-agnostic. React Final Form was popular pre-React Hook Form. Less active today.…
The #1-rated tool in the React 2025 survey. Async state management — fetching, caching, syncing server state. Not a state library exactly but solves what most React apps actually needed Redux for. Def…
#2 in the React survey. Tiny, no boilerplate, hook-based. Replaced Redux for most teams. Stays out of your way until you genuinely need it.…
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.…
Modern Redux. Massively better DX than classic Redux but still more boilerplate than Zustand. Still relevant for big enterprise apps with established Redux patterns and devtools requirements.…
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 default React router. ~53k stars. v7 merged Remix into React Router so it now also does data loading and form actions. Best choice for React SPAs and SSR apps not on Next.js.…
Type-safe router with first-class search-param handling. The router that powers TanStack Start. Stronger types than React Router but newer ecosystem.…
~1.5kb router for React. Sometimes that is exactly what you want — a marketing site, an embedded widget, a Chrome extension popup.…
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…
The build tool that won. ~71k stars. Dev server is instant, build is fast, plugin ecosystem is rich. Default for most non-Next.js React/Vue/Svelte projects in 2026.…
Content-first framework with islands architecture. ~47k stars. Ships minimal JS, multi-framework component support (React + Vue + Svelte in one project). Best choice for content-heavy sites where Next…
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.…
Vue's Next.js. ~56k stars. Mature, great DX, strong ecosystem. The default for Vue apps that need SSR and SEO.…
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.…
The way to build React Native in 2026. ~32k stars. Managed workflow that handles native builds (EAS), updates (OTA), and routing (Expo Router). Default for cross-platform mobile unless you have hard n…
The cross-platform mobile framework. ~120k stars. Most people use it through Expo now. New Architecture (Fabric + TurboModules) shipped widely and improved performance significantly.…
Universal UI for React Native + web. Compile-time style extraction means near-native performance. The best option in 2026 for genuinely sharing UI code across web and mobile.…
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.…
TypeScript-native headless CMS. ~30k stars. Self-hostable, code-first schema, generated TypeScript types. Best choice in 2026 for builders who want a CMS that respects code workflows.…
Headless CMS layered on top of any SQL database. ~28k stars. Strong when you have an existing database and want a no-code admin UI bolted on.…
Headless CMS with admin UI. ~64k stars. Mature, large community, plugin ecosystem. Heavier than Payload, more familiar if you come from WordPress.…
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…
Lightweight, privacy-friendly Google Analytics alternative. Cookie-less, GDPR/DPDP-friendly. Self-host or use their managed service from ₹720/year.…
Self-hosted Plausible alternative. ~22k stars. Free if you can run a Node process and a Postgres database.…
Fast, typo-tolerant search engine in Rust. ~48k stars. Easiest search engine to operate — single binary, sensible defaults, great DX. Good middle ground between Postgres full-text and Elasticsearch.…
C++ search engine with similar DX to Meilisearch. ~21k stars. Slightly more mature on some clustering features. Either is fine — pick the docs you like better.…
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.…
Composable charting library for React. ~24k stars. Built on D3 but with a much friendlier API. Default choice for dashboards and analytics UIs in React.…
The data visualization library. ~108k stars. Steep learning curve but unmatched flexibility. Used under the hood by most React charting libraries. Reach for it when off-the-shelf charts cannot do what…
Mature, feature-rich charting library with strong support for complex chart types (sankey, treemap, candlestick). Heavier than Recharts but richer out of the box.…
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.…

Headless rich-text editor built on ProseMirror. ~28k stars. The default in 2026 for embedded editors in SaaS apps — Notion-style document editing, comments, blog posts.…
Meta's extensible text editor framework. Used in Facebook and Instagram. More framework-y than Tiptap, steeper learning curve, more powerful for complex editors.…
Notion-style block editor built on Tiptap. Higher abstraction — drop it in and get a Notion-clone editor without configuring blocks yourself.…
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 Heroku/Vercel alternative. ~30k stars. Deploy from Git to your own VPS. Good for indie devs avoiding Vercel costs at scale.…

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 Python scraping veteran. Mature ecosystem, plugins for everything (caching, proxies, middlewares), and a years-honed pipeline architecture. Steeper learning curve than the modern alternatives but …
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…
Chrome-only browser automation from Google. Slightly more raw than Playwright with fewer batteries included, but lighter weight and battle-tested on Chrome quirks. The choice when Playwright's multi-b…
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…
