For developers just starting out, PostHog is a free way to understand how your product is being used, without having to send any data to 3rd parties.
For enterprise customers, one data security becomes a key concern, or B2C businesses where using a SaaS solution is unaffordable, it's typical to see teams hosting an event capture platform, a data lake, and sophisticated analytics tools. The end result is that data scientists are needed and most developers don't have easy access to product intel. PostHog solves that gap - it lets everyone understand how your product is being used, without having to send data to 3rd parties, even once you have scaled to millions of visitors.
It has a JS snippet that can autocapture events, and pre-built libraries to push backend data to. Build up full user histories, visualize product trends, funnels, and run experiments with new features.
Chrome DevTools PostHogPostHog is particularly well-suited for product teams, developers, and startups that require deep insights into user interactions and need the flexibility of a self-hosted solution. It is also a good fit for organizations that prioritize data privacy and want to maintain full control over their data.
PostHog might be a bit more popular than Chrome DevTools. We know about 73 links to it since March 2021 and only 55 links to Chrome DevTools. We are tracking product recommendations and mentions on various public social media platforms and blogs. They can help you identify which product is more popular and what people think of it.
You hit a bug. You open the logs. You switch to the code. You check the database. You open the browser dev tools (like Chrome DevTools). You go back to the logs. Every switch costs you mental context. Studies show it takes 15–25 minutes to regain deep focus after a context switch. A single debugging session can involve dozens of them. - Source: dev.to / 6 months ago
Familiarize yourself with two built-in tools you will use repeatedly. First, Chrome's internal task manager, which you open with Shift+Esc on Windows and Linux or through the Window menu on macOS. Second, the DevTools Performance panel, accessible via F12 or Cmd+Option+I on Mac. Both of these are essential for diagnosing which specific tab, extension, or process is responsible for the slowdown you are experiencing. - Source: dev.to / 6 months ago
The copy() function is a DevTools-specific API documented in the Chrome DevTools reference. It writes directly to the system clipboard. For a broader look at what DevTools offers, check out the browser developer tools overview on zovo.one. - Source: dev.to / 6 months ago
YouTube uses infinite scrolling to load new elements on the page, similar to what we discussed in the corresponding article from the Apify team. Let's look at how this works using DevTools and the Network tab. - Source: dev.to / about 1 year ago
Let's look at what happens under the hood when we scroll a TikTok page. I recommend studying network activity in DevTools to understand what requests are going to the server. - Source: dev.to / over 1 year ago
What it deliberately does not have: accounts, cloud sync, a marketplace, Or any paywall. Telemetry is opt-in, off by default, anonymous, and collects Zero content — the endpoint is configurable if you'd rather self-host PostHog. It's free software, and it will stay that way. - Source: dev.to / about 1 month ago
Opus, zero nudges. Realised on its own that an abandoned signup never fires identify, triangulated the anonymous session from time, platform and registration events, decoded the PostHog replay blobs, confirmed the duplicate account in Supabase, proved the reset email never sent, and pulled the root cause out of an unmasked DOM field. One prompt in; root cause out. - Source: dev.to / about 2 months ago
