Skans.jl VS Sentry

Fairly simple project with, I think, a lot of potential.

The idea is that checking web pages for changes requires (1) a place to store the previous state (2) a way to run the check on a schedule and (3) notify someone that the page has changed.

After fiddling for a few weekends with GitHub, this project can now check pages for changes on a schedule. I'm using it myself and so far it works very reliably. For *testing*, I'm monitoring https://bbc.com. You can see a typical output of a Skans notification there, at https://github.com/rikhuijzer/Skans.jl/issues/10#issuecommen...

Monitor and Tune Caching Performance: Continuously monitor caching metrics like hit ratio, eviction rate, and utilization to assess effectiveness. Fine-tune configurations based on observed performance and user behavior to optimize cache use and derive maximum benefit. Tools like Sentry are developing features to help track cache performance.

1) Do you have two separate codebases for free and paid?

No. Sentry has one codebase between free and paid. We have a Django monolith plus some services where all our features are implemented:

Sentry is a powerful tool in the realm of performance monitoring and error tracking, adept at automatically identifying bugs and errors within your codebase. With SDKs available for virtually all widely used frameworks and technologies—including JavaScript, PHP, Python, and Ruby—Sentry is ready to integrate seamlessly into your projects.

First, sign up for a free account at https://sentry.io. Create a new project and make note of your DSN (Data Source Name).

Using APM tools like NewRelic, Sentry, Datadog, etc to monitor the performance of your application and while you're on it, they can help you identify N+1 queries.

However, ensuring the reliability and performance of your Next.js app is equally crucial. That’s where Sentry comes into play. Combined with Sentry, an industry-leading error monitoring platform, Next.js empowers developers to proactively identify and resolve issues that may arise in their applications. In this article, we’ll explore how to integrate Sentry into your Next.js project for effective error monitoring and performance optimization.

Sentry: Error monitoring for applications, including APIs. Also offers application performance monitoring (APM).

Indeed, webapps are not immune to distribution problems. Wayward and invasive browser extensions are a clear threat, as are 3rd-party dependencies (and their dependencies) loaded at runtime. Which is why companies like https://sentry.io exist. I think the difference is that webapps are "distributable by default" and it takes real work to break this. Versus having local desktop apps which require work to distribute. A potent example of the power of defaults.

Sentry produces nothing of value? You don't value an open source error tracking and performance monitoring platform? https://github.com/getsentry/sentry

> You invent something, and then immediately turn it into a cheap commodity by releasing it for free.

Exactly. A 71-line python script https://github.com/getsentry/sentry/commit/3c2e87573d3bd16f6... was groundbreaking when it came out and the fact that it springboarded into a startup is commendable.
