lbd-followback

Check who follows you back on Letterboxd.

Scrapes a user's following and followers, then compares them to identify mutuals, people not following back, and people you don't follow back. Outputs an HTML report with collapsible sections and profile links.

Usage

lbd-followback <username>
lbd-followback <username> -f          # bypass cache
lbd-followback <username> -j          # JSON summary
lbd-followback <username> --no-report  # terminal only
lbd-followback <username> -o report.html  # custom path
lbd-followback <username> -O          # open in browser
lbd-followback <username> --delay 5   # override page delay

Report written to <username>_report.html in current directory.
Cache stored at ~/.cache/lbd-followback/.

Python API

from lbd_followback import scrape, analyze, generate

following, followers = scrape("nmcassa")
analysis = analyze(following, followers)
generate("nmcassa", following, followers, analysis)

How it works

1. Scrapes all following and follower pages with rate-limited requests (3-4s delay between pages, 429 backoff)
2. Caches results to ~/.cache/lbd-followback/ for 24 hours
3. Compares the two sets to find mutual, not-following-back, and not-followed-back users
4. Generates a dark-themed HTML report with avatars, profile links, and collapsible sections

Install

Requires Python 3.14+.

# via PyPI (recommended) — install globally then run
uv tool install lbd-followback
pipx install lbd-followback
lbd-followback <username>

# from source — install globally then run
uv tool install .
lbd-followback <username>

# from source — run directly without installing
uv run python -m lbd_followback <username>

Note: letterboxdpy depends on curl-cffi which uses CFFI to interface with curl-impersonate (C/C++). On some systems a C compiler toolchain (gcc/clang/MSVC) may be required. uv tool install handles this automatically.
