PaidYet is a Telegram bot that runs on your laptop, for the friend who always says "haan bhai, kal bhej dunga" ("yeah, I'll send it tomorrow") and then forgets. Send it a bill photo or a line like "Rahul ko 500 dene hai Friday tak". Gemma, running locally in Ollama, reads it, and you tap Save. Then a durable Temporal workflow keeps reminding you until you tap Paid. Sentry traces every step without seeing a single bill.

Structlog takes a different approach. Rather than wrestling with object hierarchies, you simply declare how each event should be processed and enriched. The result is logging that feels natural to write, while producing output that works just as well for humans skimming a console as it does for machines ingesting JSON into an observability platform.

An OpenTelemetry SDK is a library that runs in your application. It collects traces, metrics, and logs from your code and hands them off for export. You install it, configure it, and call its APIs (or rely on auto-instrumentation) to emit telemetry. For Python agents, the OpenTelemetry Python SDK is the foundation. For TypeScript, OpenTelemetry JavaScript serves the same purpose.

Project mention: Stop the event loop stall: a Sentry Python SDK fix for slow local-variable capture | dev.to | 2026-08-11
This entry is a real, tested bug fix in the Sentry Python SDK for issue #6649. On FastAPI 0.137 and newer, logging a single exception could freeze an async service for seconds because Sentry was building a giant text representation of the framework's internal router objects while capturing stack-frame locals. The fix makes that capture bounded and fast without changing what data ends up in Sentry for normal cases.

I often use [snoop](https://github.com/alexmojaki/snoop) because I like the features and output formatting, but it doesn't support async. I have found [ASnooper](https://github.com/LL-Ling/ASnooper), but it only supports async. I'd like to add ASnooper's async feature to snoop.
I'm thinking of creating a project that imports both, and patches the relevant parts of snoop with the async functionality from ASnooper. I have some notes from looking into the snoop code:

I want to share small library which i made.
While I developing my log viewer (https://github.com/iamtelescope/telescope) I needed a way for users to filter the data in my UI.
