Top 23 TypeScript Nextj Projects
-
dify
Build Agentic workflows, RAG pipelines, with rich AI model and tool support on one collaborative workspace. Deploy on cloud, VPC, or self-hosted, so teams move from prototype to production without rebuilding the stack.
Project mention: 7 Best Lovable Alternatives in 2026 (When You Need More Than a Prototype) | dev.to | 2026-07-127. Dify
-
Puter.js
Puter.js - The Backend for AI-Generated Apps. One-shot full-stack apps with your existing AI coding tool. Puter.js gives you Auth, Storage, DB, AI & more, with up to 90% fewer AI tokens than other backend platforms.
-
shadcn/ui
A set of beautifully-designed, accessible components and a code distribution platform. Works with your favorite frameworks. Open Source. Open Code.
UIAble is a free, open-source UI component library built with Tailwind CSS, Shadcn-style architecture, and Base UI principles. The idea is straightforward: reusable components should stay flexible, readable, and easy to maintain.
-
supabase
The Postgres development platform. Supabase gives you a dedicated Postgres database to build your web, mobile, and AI applications.
Project mention: Supabase Schema Diagram: Get an ERD You Can Keep, Not a Dashboard View | dev.to | 2026-08-01The layout lives in your browser, not in the project. Early versions opened vertically stretched and dropped your repositioning entirely; Supabase has since fixed the persistence half, so a dragged table now keeps its position across refreshes. But it keeps it in exactly one place: that browser's localStorage, keyed to the project and schema. Nothing syncs to the project itself - a teammate opening the same visualizer gets the auto-layout, a new laptop starts from zero, clearing site data erases the arrangement, and the relationship lines cannot be reshaped at all. An arrangement only one browser can see is a preference, not documentation.

LobeHub
The ultimate space for work and life — to find, build, and collaborate with agent teammates that grow with you.
Project mention: Show HN: AI Roundtable – Let 200 models debate your question | news.ycombinator.com | 2026-03-24You can set this up yourself with API keys to the corresponding providers and creating an Agent Group in https://github.com/lobehub/lobehub. Agent groups allow you to easily create a room of agents and have them discuss any of your topics. Easily make agents with types and skills, it even assists in drafting starting prompts and even team members depending what your query (and selected model) is.
You can self-host as well, but not via desktop app. Sever setup required.
Be careful of your token context, you can easily rack up costs if you leave Opus selected as the model and get lost in some rabbit hole of results.
Enjoy enjoy!

Appwrite
Appwrite® - complete cloud infrastructure for your web, mobile and AI apps. Including Auth, Databases, Storage, Functions, Messaging, Hosting, Realtime and more

Project mention: Math.random() Is Not Random Enough. I Found It Building API Keys in a 44K-Star Repo. | dev.to | 2026-05-29
I found this in our benchmark corpus, extracted verbatim from Cal.com's Make integration setup (~44K GitHub stars):

AppSignal knows why the f*#k it crashed. Stop vibe-debugging. Every exception, every backtrace, grouped so you see patterns, not noise.
-
jsoncrack.com
✨ Innovative and open-source visualization application that transforms various data formats, such as JSON, YAML, XML and CSV into interactive graphs.
Copy this JSON and paste it into jsoncrack.com or any JSON tree visualizer. You'll see your AST as an interactive tree diagram. Click around. Explore the structure. See how factorial(n - 1) is represented. See how the if-expression contains three sub-expressions. Every node, every connection - it's all there.

payload
Payload is the open-source, fullstack Next.js framework, giving you instant backend superpowers. Get a full TypeScript backend and admin panel instantly. Use Payload as a headless CMS or for building powerful applications.
That's payloadcms/payload#17138, one line: skip the handler when event.nativeEvent?.isComposing is true. I've filed close to identical fixes in dozens of other projects. Not similar bugs. The identical bug, in code that has never seen the others.

-
CopilotKit
The Frontend Stack for Agents & Generative UI. React, Angular, Mobile, Slack, and more. Makers of the AG-UI Protocol
This is the Payload bug, and it's the largest bucket by a wide margin: 40 of the 129 entries, 31 percent, more than any other single category in the corpus. It shows up in React, Vue, Svelte, Angular, and every headless component library that lets you bind a handler to Enter. CopilotKit/CopilotKit#5764 has the same shape in an Angular chat widget: the composer submitted the message on the Enter that confirms an IME composition instead of waiting for the real one. Different framework, different UI, same missing isComposing check. The fix is always one line. The bug survives review because most contributors, and every CI runner, type in a language where a keystroke and a finished character are the same thing.

Project mention: Ditch Vercel & Netlify: The Best Self-Hosted Alternatives in 2026 | dev.to | 2026-06-01
GitHub: Dokploy/dokploy (34K+ stars) License: Apache 2.0 Best for: Developers who want a Vercel-inspired UI with Docker Swarm clustering
-
Refine
A React Framework for building internal tools, admin panels, dashboards & B2B apps with unmatched flexibility.
Project mention: Open Source Retool Alternative: A Code-First, AI-Native Approach | dev.to | 2026-04-28Refine: github.com/refinedev/refine

Postiz surprised me the most, and in a good way.

Project mention: GraphQL vs REST: 18 Claims Fact-Checked with Primary Sources (2026) | dev.to | 2026-04-17
Historically, measurements around 40–45 KB gzipped were reasonable for older Apollo Client bundles , but recent v4.x releases have reduced bundle size and made features more modular. Regardless, that is not a cost of GraphQL itself. The same concern exists for feature‑rich REST clients like SWR or TanStack Query . It is a misleading comparison because both REST and GraphQL can be implemented with nothing more than fetch(). Therefore, the theoretical baseline for both styles is 0 KB.

signoz
SigNoz is an open-source, OpenTelemetry-native observability platform for your team and their AI agents. Get logs, metrics, and traces in one tool with features like APM, distributed tracing, log management, infra monitoring, etc. Combined with SigNoz MCP and a native AI teammate (in SigNoz Cloud) it helps you build more resilient apps.
Project mention: I built an agent that asks your app what happened to it on SigNoz | dev.to | 2026-07-25So I built Why Did It Break. It's an investigation agent on top of SigNoz. You ask a question the way you'd ask a colleague ("why is checkout slow?") and the agent runs live queries against SigNoz, follows leads like an engineer would, and comes back with the root cause, the evidence, a suggested fix, and how confident it is. Every claim links to the exact trace in SigNoz that proves it.

Project mention: Web3 Growth Stack Explained: Tools, KPIs & Strategies for Onchain Growth | dev.to | 2026-03-23

-
sim
Build, deploy, and orchestrate AI agents. Sim is the central intelligence layer for your AI workforce.
Sim ai is an alternative to Heym
-
FastGPT
FastGPT is a knowledge-based platform built on the LLMs, offers a comprehensive suite of out-of-the-box capabilities such as data processing, RAG retrieval, and visual AI workflow orchestration, letting you easily develop and deploy complex question-answering systems without the need for extensive setup or configuration.
-
nx
The Monorepo Platform that amplifies both developers and AI agents. Nx optimizes your builds, scales your CI, and fixes failed PRs automatically. Ship in half the time.
Angular, React with its whole ecosystem, Nx with its monorepos: these are powerful tools, built by humans to coordinate teams of humans on massive codebases. And for that purpose, they're often the right choice — if your primary constraint is coordinating hundreds of engineers over a decade, the conventions and tooling of an established framework earn their keep.
-
The T3 stack represents a different philosophy, prioritizing end-to-end type safety over everything else. Built on Next.js, the stack combines tRPC for type-safe APIs, Prisma for type-safe database access, NextAuth.js for authentication, and Tailwind CSS for styling. The result is remarkable: change your database schema, and TypeScript immediately highlights every place in your frontend that needs updating.

Project mention: What the React 2025 Vulnerability Taught Me About Solo Dev Security | dev.to | 2025-12-18
I use libraries for authentication rather than building it myself. For Memoreru, I chose Better Auth. Auth.js is also an option.
