Parsing MRT dumps without shipping them off
The main point is simple: parsing happens locally in the browser. Nothing needs to be uploaded just to inspect a dump, which avoids the usual wait for a remote parser and the awkward question of where the file has gone.
That fits MRT files better than most web tools do. Route collector data is often bulky and compressed, and the useful part is usually a handful of events rather than the whole archive. Browser-side parsing keeps the file handling close to the user, which is useful when the dump sits on a workstation, a laptop, or some temporary storage that is not meant to leave the machine.
The explorer supports gzip and bzip2 compressed files, so it can work with the formats commonly used for these archives without a manual unpack step first. A sample file is included too, which is handy when the point is to see how the viewer behaves before pointing it at a real dump.
Reading the event list: prefixes, paths, and attributes
Once parsed, the tool lists BGP events with a timestamp, prefix, AS path, OTC and community attributes. That is the part that matters when trying to spot what changed and when. The dump stops being a block of routing noise and turns into a sequence of discrete events with route data attached.
The modal view goes further and shows extra properties plus the full event JSON. That is useful when the visible row is not enough, especially if a route attribute needs checking against the underlying event object. It also keeps the main list readable while still giving access to the raw structure when needed.
For route analysis, the useful boundary is obvious: the explorer is a viewer, not a full analysis stack. It helps you inspect BGP announcements and related metadata quickly, but the value comes from how it exposes the event record, not from trying to pretend the browser has become a route research lab.
Loading remote or local files in practice
Files can be loaded in three ways: paste a URL, drag and drop a file, or pick a local file. That covers the common cases without forcing a single workflow on everyone.
Loading by URL is convenient when the dump already lives somewhere reachable over HTTP. The query string captures the source, so the current file can be shared or revisited without re-entering the address. Drag and drop is the quick route for local files, while the browse option is the safer one when the file picker is easier than wrestling with a touchpad.
The main constraint is still size and format. MRT dumps from collectors can be large, and compressed files are the normal case, not the exception. Browser-side parsing avoids uploading the data, but it still needs to do the work on the client, so the practical limit will be whatever the machine and browser can handle comfortably.
