Hi, Product Hunt! 👋

I’m the creator of TraceTUI. Like many developers and DevOps engineers, we spend most of our time looking at logs. To be honest, it’s driving me crazy that I had to constantly open several tail -f windows, lose track of the events, or sort through confusing grep results just to track down a single error in the service’s operation.

I needed something lightweight, lightning‑fast, and designed exclusively for the terminal. Therefore, I created TraceTUI based on Textual.

What makes it useful:

• 🔀 Timeline merging mode: upload several log files at once, press M, and they will be merged into a single chronological stream (each source will be highlighted in its own color).

• 💻 Three‑panel interface: monitor log sources on the left, view the main stream in the center, and examine full stack traces or metadata on the right.

• ⚡ Smart navigation: press E to instantly jump to the next real error (skipping all informational and debug noise), or press F to filter text on the fly.

• 🔍 Autodetection: the program automatically recognizes loguru, standard Python logging, and simple formats.

Fully open‑source (MIT), and it can be used via pip install tracetui.

I will be very glad to receive your feedback, wishes, and suggestions.
