Codag

What it does

Visualize your LLM workflows as interactive & shareable graphs. Point Codag at your codebase — it maps every LLM call, branch, and data flow. Click any node to jump to source. Live updates as you code. Self-hosted, open source.

Codag cuts coding-agent costs without changing how developers work. One command attaches it to Claude Code and Codex, and it teaches your agent to read large tool results efficiently.

# codag npm test printed 4,212 lines. your agent reads this instead: FAIL src/checkout.test.ts > applies discount codes AssertionError: expected 500 to equal 502 at src/checkout.test.ts:118 the other 4,180 lines were passing suites. skipped, and your agent can pull any of them back word for word. ~75% compression the problem Test runs, search results, file trees, logs. One big result can push out everything the agent already learned and force another expensive lap. A session makes hundreds of tool calls, and a handful carry the answer. The rest is billed input the model reads once and throws away. No wrapper command, no config files to edit, no new workflow to learn. Setup attaches the…from codag.ai

  Codag – Visualize and share LLM workflows in VS CodeFeb 2026 · github.com · ▲6

  I built Codag because I kept getting lost in my own AI code. You're chaining 3 LLM calls across 5 files. A prompt change breaks something downstream. Which call? Which branch? You grep for "openai.chat", open 8 tabs, trace the flow manually. Codag automates this: - Point it at your codebase and it extracts every LLM call, decision branch, and processing step - Renders an interactive and shareable DAG with clickable nodes that link back to source - Live updates as you edit using tree-sitter — no waiting for re-analysis Supports OpenAI, Anthropic, Gemini, LangChain, LangGraph, CrewAI, and…

  Turn any workflow diagram into compilable, running and stateful code2025 · workflows.diagrid.io · ▲109

  Hi HN folks, I'm a co-creator of the Dapr CNCF project and co-founder of Diagrid. Today we announced a free-to-use web app that takes any form of workflow diagram (UML, BPMN, scribble in your favorite drawing tool or even on paper) and generates code that runs in any IDE and that can be deployed to Kubernetes and other container based systems, based on Dapr's durable execution workflow engine. This essentially allows you to run durable workflows in minutes and leaves out the guesswork for how to structure, code and optimize a code-first workflow app. I'm happy for you to give this a try and…

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  I spent 3 years reverse-engineering a 40 yo stock market sim from 1986▲721

  Hello my name is Ben Ward for the past 3 years I have been remastering the financial game Wall Street Raider created by Michael Jenkins originally on DOS in 1986. It has been a rough journey but I finally see the light at the end of the tunnel. I just recently redid the website and thought maybe the full story of how this project came to be would interest you all. Thank you for reading.
