Reddit Subreddits25 Archive
This repository contains a compressed Reddit archive organized by subreddit and record type.
It was prepared from a local bundle named reddit_torrent_download_bundle; that bundle did
not include provenance or licensing documentation, so users must independently verify that
their use complies with applicable terms, licenses, privacy requirements, and laws.
Contents
- Files: 79,955 (39,974 comment shards and 39,981 submission shards)
- Compressed size: 3,965,777,405,390 bytes (approximately 3.97 TB)
- Encoding: newline-delimited JSON compressed with Zstandard
- Layout:
data/<comments|submissions>/<sha256-prefix>/<subreddit>_<type>.jsonl.zst
The two-character hash directory is derived from the original filename and only exists to
keep repository directories small. manifest.tsv records every remote path, compressed size,
and original filename.
Reading a shard
zstd -dc data/comments/00/example_comments.jsonl.zst | python -m json.tool --json-lines
In Python, use the zstandard package and parse one line at a time; shards can be very large.
Schema and field availability vary across Reddit eras and between comments and submissions.
Safety and privacy
This historical archive can include deleted, offensive, explicit, or personally identifying content. Do not treat continued presence in the archive as consent for reuse. Apply appropriate filtering and governance before training models, redistributing excerpts, or exposing records.
