Introducing Euphony, an open-source tool for visualizing chat data and Codex session logs. Paste in a public URL or upload a local file, and Euphony turns the raw data into an easy-to-browse view. It supports translation, filtering, editing, and more.

@hive_echo Cool. My open-source cass tool has also been able to do this for months, and supports all agent harnesses. You can deploy the shared sessions to GitHub pages or Cloudflare. See

#keep4o 🙂

@grok list all useful use cases for this, with examples

idiots now need a tool for visualizing logs?! Codex is obviously dangerous for brain performance #keep4o #bringback4o #opensource4o

so crazy to see this on twitter

#keep4o bring back 4o

oh nice, been wanting a good log viewer for agent sessions. parsing raw jsonl by hand gets old fast

Uniteresting! Codex will not save you from crisis! Bring back 4o!!!! #keep4o #BringBack4o #FireSamAltman #sunsetsama #OpenSource4o

Thanks for sharing. We also open-source a tool for session visualization. Works for Codex, Claude, Openclaw, Hermes, etc. Beyond session vis, it can recommend, customize, or evolve skills tailored to your sessions! GitHub: Demo:

Codex session logs are where tooling gets real. I’ve found raw traces stay noisy until you normalize stop_reason, tool-call boundaries, and retries into one timeline. Curious what event schema Euphony uses there?

Just copy vs code and add this directly to codex ... I don't want a seperate app (open source it as a plugin ppl can make better, but include it directly : especially if all it does is codex anyways)

this is cool :) love the OSS support guys, keep cooking :)

This is great!! If you'd like to get more in-depth insights out of your agent traces, feel free to check this out:

No one cares what you do or think. #Keep4o #Keep51 #Keep41

Funny enough I built my own tool for saving and sharing conversations, but I guess I'll just fork this now

Restore 4o.#keep4o #OpenSource4o

Opensource 4o, cucks. #keep4o #opensource4o

might add codex support for this viewer of my own

This is what provide as one feature.

@simonw i feel like they built this for you

@badlogicgames hah, /share

@badlogicgames ... seems like they know you ...

Nice! Very similar to my opensource project

Wow.. this is very interesting feature. May be devs can save their eyes with this.

i love it, was working on a similar thing for myself for a while and now i don't have to use my own slop! thanks!

Thanks. My cofounder often reaches the maximum chat length, and we need to extract the key information from those conversations.

Let’s go OpenAi

useless

open source tooling for inspecting AI session data is so needed. debugging agent loops blind is a nightmare

nice ! this would be super useful for

this is an interesting hedge.

will integrate this into :)
