Flux: an IDE for logs on your Mac
Read your logs like code in a native macOS log explorer
Flux is a native macOS log explorer for engineers debugging production. It connects to Graylog, Elasticsearch through Kibana, or local files and Docker, and turns your logs into a tree of services, streams and endpoints with request counts and error rates. Query with Lucene and completion over real field values, trace any ID across every stream, map services from logs, and follow a failing request down to the commit behind it. Claude Code reads the same logs over MCP. Tokens stay on your Mac.
Hi Product Hunt, I'm Emre, the maker of Flux! 👋
Flux is the log explorer I wanted every time production broke.
I'm a backend engineer, and a good part of my week is reading logs. An error rate climbs, someone pings the channel, and I open a search box. That's where it always went wrong. A search box treats logs as one flat river of text: you type a query, read the answer, and the moment you look somewhere else it forgets everything. The structure that actually matters (which service, which stream, which endpoint) survives only as strings you retype. Comparing two endpoints meant editing the same filter twice.
My code editor never worked like that. Code has a tree, tabs, completion and a key that finds anything. So I built the same thing for logs.
Flux is a native macOS app that connects to Graylog, Elasticsearch through Kibana, or a folder of log files and your Docker containers. Here's what it does today:
🌳 Your logs as a tree: Connection › Project › Stream › Endpoint, each endpoint with its request count and error rate. /users/123 and /users/456 are one endpoint, /users/:id.
🗂 Every stream and endpoint opens in its own tab, with a Lucene console that completes field names and the values those fields actually hold.
🔎 Trace any ID (a request id, an order, an email) across every stream at once, and see which service said what and where it failed.
🧭 Select a failing row and press ⌥⏎: Flux gathers the request across services, who else it hits and the commit behind it, then hands the case to Claude Code.
🤖 Claude Code in your terminal reads the same logs through the same connections over MCP. After a deploy it can leave a saved query behind, and Flux watches it for you.
🔒 Read-only and local: Flux never writes to your log store, and your connections, tokens and saved queries never leave your Mac. Tokens live in the macOS Keychain.
Flux is young and moving fast. I'd love to hear which log store you want next, and what still sends you back to the web UI.
Download it at flux.emreb.dev and tell me what you think, especially the parts that annoy you.
Happy debugging,
Emre
