The tools
Five extensions, one job each
Four look at your own site, one looks at your competitors. Each opens next to the page you are on, answers one question well and gives you a report you can send.
What do you do?
All five tools. Pick a role to see where to start.
HitlineAnalysts and marketers
Is every tag and event really firing?
Watch GA4, Meta, TikTok and Google Ads events as they fire, check GTM, server-side GTM and consent, then export an audit.
Yes. There is no paid plan and no trial. They are free because they show the kind of work I do for clients: if you need the fixes done, you know where to find me.
What data do the extensions collect?
None. Each extension saves only its own settings on your computer. The pages you check are read in your browser and nothing is sent to a server.
Do they slow down Chrome?
No. Nothing runs in the background. A tool only works on a tab after you click its icon or press its shortcut there.
Which one should I install first?
Pick your role in the tool list above. If you run paid campaigns, start with Hitline: broken tracking costs the most and is the hardest to see.
Can I use them for client work?
Yes. Agencies use the PDF reports in audits and pitches. The reports carry a small "Made with" line and nothing else.
Which languages do they support?
English and Azerbaijani. You can switch the language in each tool's settings.
Built by one person
Need the fixes done, not just found?
I am Shamistan Isayev. I work on analytics, server-side tracking and CRO, and I built these tools for the checks I run on every project. When you want someone to fix what they find, book a call.
