BigLeaf App Review sample files

Upcoming version 1.2.0: the "v1.1 and later" wording below was an unpublished development label. The next public release is version 1.2.0.

Until version 1.2.0 is released, the public App Store version remains 1.0.0, and the Preview Mode / purchase / Restore behavior described below still applies. Version 1.2.0 will let you view, search and jump through every record without a purchase. All sample files, URLs and byte sequences remain unchanged; the older descriptions are preserved below.

Note (v1.1 and later): BigLeaf is completely free. The Preview Mode / purchase / Restore behavior described below applied to version 1.0.0 only.

The files, URLs and byte sequences on this page are frozen for future reviews and are never rewritten, so the descriptions further down still use the version 1.0.0 wording. In version 1.1 and later there is no file-size limit: every record of every file below is browsable, searchable and jumpable, and no purchase is offered anywhere in the app for that.

Download any file directly. These URLs and byte sequences are frozen and will remain available for future reviews. SHA-256 values are shown for integrity verification.

Fastest path to Preview Mode and the purchase

Download file 6 and open the .gz directly in BigLeaf with Cmd-O, drag it onto the BigLeaf window, or drop it on the Dock icon. Do not decompress it first—opening gzip directly is a BigLeaf feature. The Preview banner appears within a few seconds after decompression passes 100 MB.

Expected behavior

In Preview Mode, search and jump cover the first 10,000 records; after purchase they cover the whole file.
Click Restore in the Preview banner to restore a prior purchase. With no prior purchase, the file stays in Preview Mode without an error dialog.
If a browser expands the download automatically, the resulting raw JSONL demonstrates Preview Mode and the purchase identically.
The indexing mechanism and interaction model are the same for this 1,551,570-record sample and the 21.5 GB / 100 GB measurements in the store listing.
Reload (Cmd-R) re-indexes an open file after it grows and cannot be demonstrated by a static download alone. Optional: while the 10 MB sample is open, run echo '{"level":"info","msg":"appended"}' >> bigleaf-sample-10mb.jsonl, then press Cmd-R.
