Top 23 TypeScript agentic-ai 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: Bind for 0.0.0.0:5432 failed: port is already allocated - find port clashes before you run docker compose up | dev.to | 2026-10-11A .env DB_PORT is the port you connect to, so changing it does not move the binding (dify#14442)
-
AppSignal
Monitoring that respects your time & budget. APM, error tracking, and dashboards for modern web apps. Ten-minute setup, transparent flat pricing, and support from engineers who actually use the product.
-
ruflo
🌊 The original agent harness. Deploy intelligent multi-player swarms, coordinate autonomous workflows, and build conversational AI systems. Features adaptive memory, self-learning intelligence, federation, vector RAG integration, and native Claude Code / Codex / Hermes and many more Integrated
Ruflo repository -- the multi-agent orchestration platform
-
composio
Composio powers 1000+ toolkits, tool search, context management, authentication, and a sandboxed workbench to help you build AI agents that turn intent into action.
Composio provides managed authentication, per-user sessions, MCP access, SDKs, and a large catalog of pre-built tools. It is best suited for individual workflows and prototype agent builds where speed of setup matters more than centralized enterprise governance.

Project mention: Harness Engineering ทักษะใหม่ 2026 จาก 10 สัญญาณบน X สัปดาห์เดียว | dev.to | 2026-09-24
[2] Walking Labs. "Learn Harness Engineering." github.com, 2026. https://github.com/walkinglabs/learn-harness-engineering
-
eigent
Eigent: The Open Source Cowork Desktop - Local and Free Alternative to Claude Cowork and Codex
Download the client from the Official Website.
-
MemOS
Self-evolving memory OS for LLM & AI Agents: ultra-persistent memory, hybrid-retrieval, and cross-task skill reuse, with 35.24% token savings and DeepSeek Harness support. (by MemTensor)
MemOS provides operations for adding, finding, correcting, and removing memories. Developers can use these operations alongside checks against their own business systems. The application chooses the authoritative source and implements the environment checks described above.
-
loop-engineering
Practical patterns, starters & CLI tools for loop engineering with AI coding agents. Design systems that prompt and orchestrate agents (inspired by Addy Osmani and Boris Cherny). Includes loop-audit, loop-init, loop-cost.
Meanwhile, the ecosystem materialized. obra/superpowers shipped a complete software development methodology built on composable skills — 1,276+ stars and growing. The cobusgreyling/loop-engineering repo cataloged patterns from Osmani and Cherny into a practical reference.

oh-my-opencode-slim
Lean, fine tuned Opencode multi agent suite · Mix any models · Auto delegate tasks
Project mention: I Read a 4-Million-Line Study of AI Coding Agents. It Described My Own Tool. | dev.to | 2026-10-05That isn't a riddle. The paper is Harness Engineering: Anatomy, Architecture, and Evolution of Coding Agents (arXiv:2609.00006), a July 2026 source-code study by Paul Barbaste, Tristan Darrigol, Germain Vu, and Tom Wiltberger of the Wavestone AI Lab. One of the eleven systems it takes apart is Pi, the harness I use every day. Another is OpenCode, the host for oh-my-opencode-slim, the plugin I sent a Korean README fix.
-
git-mcp
Put an end to code hallucinations! GitMCP is a free, open-source, remote MCP server for any GitHub project
-
Backlog.md
Backlog.md - A tool for managing project collaboration between humans and AI Agents in a git ecosystem
Project mention: pinto: A Git-Native Scrum Backlog and Kanban Board for Your Terminal | dev.to | 2026-07-15If this sounds familiar, take a look at Backlog.md. It is an excellent Markdown-native project manager with a terminal board, a local web UI, search across tasks and project knowledge, and agent workflows through CLI instructions or MCP.
-
Project mention: Bugs Are Innocent Until Reproduced: Building Verdict, an Evidence-First Agent Harness | dev.to | 2026-08-29
Verdict reproduced TrueForge issue #417, where snapshot registration can wait indefinitely when an upstream request never resolves.
-
typia reads your TypeScript types at build time and emits a serializer from them. typia.json.assertStringify() validates first and points at the field - invalid type on $input.id - so it's genuinely safe, and the runtime cost is near zero because everything is inlined at build. The price is the build: you need ttsc or the unplugin wired in, it can't run from plain JavaScript, and there's no schema value at runtime to hand to anything else. bigint is also prohibited outright in its JSON functions, so back to a manual mapper for those. Recommended if you like compile-time tools.
-
eko
Eko (Eko Keeps Operating) - Build Production-ready Agentic Workflow with Natural Language - eko.fellou.ai
Project mention: I built an open-source AI browser that automates web tasks with natural language | dev.to | 2025-11-03Special thanks to Eko for the powerful agent framework.
-
agent-device
Mobile app automation and verification for AI coding agents. CLI, MCP server, and typed Node.js API for iOS, Android, HarmonyOS, TV, web, macOS, and Linux.
Project mention: Giving your coding agent eyes on a React Native app: Argent vs agent-device, measured | dev.to | 2026-10-09Coding agents used to stop at "it compiles". In 2026 a set of tools lets them run the app, tap through it, read the screen and profile it. Two are built with React Native in mind: Software Mansion's Argent and Callstack's agent-device. Both claim to close the loop. I wanted to know what that looks like on a real app, and what it costs.

In case you are looking for an open-source alternative without vendor lock-in (https://github.com/agenta-ai/agenta)
-
flyde
Open-source Visual programming for backend logic that integrates with existing codebases. Flyde bridges the gap between technical and non-technical team members. Product managers, designers, and backend developers can collaborate on the same visual flows.

crystal
(Crystal is now Nimbalyst) Run multiple Codex and Claude Code AI sessions in parallel git worktrees. Test, compare approaches & manage AI-assisted development workflows in one desktop app. (by stravu)
Project mention: Show HN: Offrun – manage every coding agent from one workspace | news.ycombinator.com | 2026-10-03 -
Project mention: PenguinHarness, an Automated Agent Builder, Right on Your Desktop / Server | news.ycombinator.com | 2026-08-14
-
Project mention: Your Agent Picked a Chart. Did the Data Deserve One? Build a UI Planner in TypeScript. | dev.to | 2026-10-10
The project README says its Jev router selects the presentation. Basic tables use A2UI; charts and more complex visuals use Open Generative UI. Its default setup requires an OpenAI key and a TypeSafe key. I verified the announcement and README, but did not run that full application.

Project mention: I built the Playwright for desktop apps. 80% token savings | news.ycombinator.com | 2026-05-01
-
Project mention: Ask HN: Is there a free MCP for web and documentation search? | news.ycombinator.com | 2026-01-17
* https://github.com/arabold/docs-mcp-server: I didn't test this, but I was turned off by the fact you have to run the server in the background instead of allowing it to be booted by the Codex instance (via npx) like it can for other kinds of MCP servers.
Does anyone have a solution to this that hits on all marks: free, able to read websites including JS ones, thorough and high-quality?
