Euphony is an open-source, browser-based visualization tool from OpenAI that transforms raw Harmony JSON/JSONL chat data and Codex CLI session logs into interactive, filterable timelines. Paste JSON, upload a file, or point it at a public URL — Euphony auto-detects the format and renders a structured conversation view. The tool surfaces conversation-level and message-level metadata through a dedicated inspection panel, supports JMESPath-based filtering for querying large datasets, includes translation support, and can run entirely in the browser without any server dependency. For developers debugging Codex agent runs or analyzing large conversation datasets, it replaces manual JSON parsing. Euphony ships as a web component library so it can be embedded in other tools, and includes a FastAPI backend mode for remote loading and Harmony rendering. It's MIT licensed and available on GitHub at openai/euphony.
Developer Tools
Intent
Describe a feature. Agents build, verify, and ship it — in parallel.

Intent, from Augment Code, reimagines the coding agent as an orchestrated team rather than a single assistant. You write a feature spec in plain language. A Coordinator Agent breaks it into tasks. Specialist Agents execute those tasks in parallel inside isolated git worktrees. A Verifier Agent checks results against your original spec before surfacing anything for your review. The spec is "living" — it updates as work progresses, and when requirements change, updates propagate to all active agents. This is meaningfully different from one-shot prompting or even multi-step agentic coding. Intent is designed for enterprise teams working on large codebases where a single feature might touch dozens of files across multiple services. The built-in Chrome browser lets agents preview local changes without leaving the workspace. It integrates with existing git workflows rather than replacing them. Launched in public beta February 2026 (macOS only, Windows on waitlist), Intent got its highest visibility yet when it hit Product Hunt with 302 votes this week. Augment Code has been quietly building toward this: their previous focus on large-enterprise codebase indexing gives Intent's retrieval layer an advantage over agents starting from scratch.
Reviewer scorecard
“Debugging Codex agent sessions used to mean manually reading JSON in a text editor. Euphony is what that developer experience should have always been — structured timelines, metadata inspection, and JMESPath filtering that actually works on large session files.”
“The parallel worktree approach is genuinely smart — agents don't step on each other, and the living spec means you're not herding a single agent through a long task linearly. For features that touch multiple modules, this could cut agent coding time dramatically. macOS-only is a real limitation though.”
“This is purpose-built for OpenAI's Harmony format and Codex sessions, which means it's primarily useful if you're already deep in the OpenAI ecosystem. Developers using other agent frameworks get limited value here unless they adapt the format.”
“Multi-agent coordination sounds great until the Verifier Agent approves something the Specialist Agents hallucinated together. Coordinated AI errors are harder to catch than single-agent errors because they have the veneer of consensus. I'd want to see extensive user testing on real enterprise codebases before trusting this in production.”
“Observability tooling for AI agents is a nascent but critical category. Euphony is a first step toward treating agent session logs with the same rigor we apply to application traces and logs — we'll see a whole category of tools like this emerge over the next two years.”
“Intent is the most concrete vision I've seen of what software development looks like when the unit of work is a feature spec, not a file edit. The living spec abstraction — where truth lives in intent, not implementation — will age well. This is the direction the whole industry is heading.”
“This is deep dev tooling with a specific niche — valuable for AI engineers but not directly applicable to creative workflows. The visualization quality is clean, but most creators won't interact with raw Harmony JSON.”
“The built-in browser for previewing changes without leaving the workspace is a small detail that shows good UX thinking. For product builders who move between design specs and implementation, having a feature spec drive coordinated agent work — and seeing a live preview — is exactly the kind of tight loop that makes creative work faster.”
