TrackJS launched a complete UI redesign after 12 years, replacing Bootstrap 2012 styles with modern CSS and Flexbox while maintaining identical functionality - "not moving the cheese." The refresh brought consistent spacing, better visual hierarchy, dark mode (by popular demand), and cleaned up o...

We are unlikely to add additional language support to TrackJS. And it's not just because of our name!

Learn from our mistakes: be careful when using VC funded companies as vendors or important parts of your stack.

Developers often undervalue their time, saying "I could build that" about tools like TrackJS. With web developers earning $56-1500/hour, building your own monitoring tool costs $9,000+ in time for a worse version of a $100 product. Focus your precious 2,150 working weeks on creating real value, n...

Instead of calculating nested aggregates for thousands of error groups then discarding most results, they first identify the top 20 groups, then enrich only those wit...

TrackJS switched from failing Mandrill to Mailgun after years of increasing email delivery problems. Key lessons: make failures visible through chat alerts, avoid abstractions until you need them, and sometimes big changes become unavoidable when dependencies deteriorate.

TrackJS finally launches error status tracking - the most requested feature ever! Set custom statuses like "Fixed" or "Investigating" on errors, filter by status across the entire UI, though Elasticsearch's immutability means large updates take time to process.

TrackJS revolutionizes error search with intelligent AND logic instead of OR, exact phrase matching with quotes, optional OR/NOT operators, and powerful global filtering that works across all UI pages - making needle-in-haystack debugging finally possible.
