24 alternatives to I made a visual test tracker to find more bugs
Headlamp is a Chrome extension that shows where you're missing tests. It reveals gaps in testing for solo testers, test teams (collaborative bug-bash, anyone?), and test automation (Selenium, Puppeteer, Playwright). Using it is easy as 1-2-3! 1) When you start testing, Headlamp puts a dot on each link and input element. 2) The dots are cleared when you click a link, type some text, or change a selection. 3) The remaining dots show you which things you missed. It also provides insightful test activity reports. It's free to use as a solo tester. Give it a try today!
Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes. I made a visual test tracker to find more bugs launched in 2022; newer entries below may have overtaken it.

Hey HN! We’re open-sourcing highlight.io (https://github.com/highlight/highlight), a session replay and error monitoring tool. Highlight.io gives you a high-precision video-like replay of what users are doing when an error or exception occurs in your web app, along with a full-fledged error monitoring experience (similar to bugsnag, rollbar, etc..). The main value prop of highlight.io is that we help you understand the full context surrounding an error and allow you to drill down to the code path that a user invoked (i.e user clicked button X, sent network request Y, and…

Hey! My name is Dima, I am from Ukraine and I am the co-founder of Lost Pixel! We built this tool to solve our problems at work and decided to open-source it so more people can build their custom visual regression testing pipelines! If you want to chat about the tool or visual regression testing in general I am super excited to meet like-minded people! Thanks a lot for checking out the product and I hope it will serve you well if you decide to try it out :D

Hey HN. We’re Jay and Vadim from Highlight.io (https://highlight.io). We’re building an open source [1] monitoring platform for web applications. Today we’re excited to be sharing a performance tool we’ve been working on, which helps you inspect the latency of code execution from the client to the server. As engineers at past startups, we often had to debug slow queries, poor load times, inconsistent errors, etc... While tools like Jaegar [2] helped us inspect server-side performance, we had no way to tie user events to the traces we were inspecting. In other words, although we had…

Hey hn! I'm one of the co-founders of highlight.io, an open source monitoring tool. Today we're sharing a ClickHouse-based logging solution we've been working on. We wanted to showcase how we built it and share how you could try it out to give feedback. Since we started working on highlight.io, we've been hyper-focused on "cohesion", or ensuring that when you install your monitoring stack, all of the resources in that stack (user interactions, requests, traces, logs, etc.) are connected in a consumable way. We've written up more about our philosophy on this here [1]. We started building…

Hey all, I've been working on this side project to get a Cypress.io-like experience, but for Ruby developers. It's plug-n-play with Capybara system tests, with the following features: - visualize assertions/commands as they happen - view all API requests, errors, and logs in the timeline - pause/continue on any step - rewind through history with a recorded video This is brand new, so looking for people to start trying it out and leave feedback.

Portal▲181Hey HN, I'm Zach, founder of Portal. Portal lets you share a live sandbox browser session as a link. Try it here: https://www.makeportals.com/try Instead of asking someone to sign up, install software, or book a demo for user research, onboarding, or sales, you send a link and they interact with the real product in a sandboxed browser environment, then you get session replays. Each viewer gets a fresh remote browser instance that starts from a defined state (URL, cookies, extensions, local files, etc). Sessions are isolated and expire automatically. The sessions have…

FlowLens▲134Hi HN, We often run into this with coding agents like Claude Code: debugging turns into copy-pasting logs, writing long explanations, and sharing screenshots. FlowLens is an MCP server plus a Chrome extension that captures browser context (video, console, network, user actions, storage) and makes it available to MCP-compatible agents like Claude Code. You can try it here: https://magentic.ai/flowlens Any feedback—good, bad, or brutal—is welcome.
