bsky-saves 0.2.0

BlueSky bookmarks ingestion toolkit: fetch, hydrate (article text, self-thread context, images), and merge into a JSON inventory.

bsky-saves

A toolkit for ingesting your own BlueSky bookmarks ("saves") into a portable JSON inventory, with optional hydration of linked article text, self-thread context, and CDN image downloads.

Why

The BlueSky web client lets you bookmark posts, but the saves are siloed inside the app. This tool pulls them out into a single JSON file you can read, archive, mirror, or build on top of.

It works for accounts hosted on bsky.social and on third-party AT Protocol PDSes (e.g. eurosky.social), because the bookmark fetch goes PDS-direct rather than through the AppView.

Install

pip install bsky-saves

Authenticate

Set two env vars from a BlueSky app password:

export BSKY_HANDLE=alice.bsky.social
export BSKY_APP_PASSWORD=xxxx-xxxx-xxxx-xxxx
# Required only for accounts hosted on a third-party PDS:
export BSKY_PDS=https://eurosky.social

The default BSKY_PDS is https://bsky.social.

Use

# Pull all bookmarks → ./saves_inventory.json
bsky-saves fetch --inventory ./saves_inventory.json

# Hydrate every external-link bookmark with the linked article's text.
bsky-saves hydrate articles --inventory ./saves_inventory.json

# Hydrate every bookmark with same-author self-thread descendants.
bsky-saves hydrate threads --inventory ./saves_inventory.json

# Decode each save's post-creation timestamp from its rkey (offline).
bsky-saves enrich --inventory ./saves_inventory.json

# Download cdn.bsky.app images referenced by the inventory into ./images/
# (flat layout). Records url→path mappings as `local_images` on each entry.
# Use --uris FILE (newline-delimited at:// URIs) to limit to a subset.
bsky-saves hydrate images --inventory ./saves_inventory.json --out ./images

All commands are idempotent: running them again skips already-hydrated entries and adds only what's new. Failures are recorded inline (e.g. article_fetch_error) so subsequent runs don't pointlessly re-hit them.

What about OAuth?

bsky-saves only supports the app-password authentication path. The OAuth + DPoP machinery for third-party PDSes lives in a separate package, atproto-oauth-py, and exists primarily for AppView-targeted resource calls that aren't reachable via PDS-direct auth. For BlueSky bookmarks the PDS-direct path (which bsky-saves uses) works regardless of where your account is hosted.
