cli-web-reddit

Reddit CLI — browse feeds, subreddits, search, user profiles, and full write operations with auth.

Quick Start

cli-web-reddit feed rising [--limit N] --json
cli-web-reddit feed popular [--limit N] --json

Output: {"posts": [{"id", "title", "author", "subreddit", "score", "num_comments", "url", "permalink", "flair", "created"}], "after": "cursor"}

Subreddit (no auth, join/leave require auth)

cli-web-reddit sub hot <name> [--limit N] --json
cli-web-reddit sub new <name> [--limit N] --json

cli-web-reddit sub rules <name> --json
cli-web-reddit sub search <name> <query> [--sort relevance|hot|top|new] --json
cli-web-reddit sub join <name> --json      # requires auth
cli-web-reddit sub leave <name> --json     # requires auth

Search (no auth)

cli-web-reddit search posts <query> [--sort relevance|hot|top|new] [--time hour|day|week] --json
cli-web-reddit search subs <query> [--limit N] --json

User (no auth)

cli-web-reddit user posts <username> [--sort hot|new|top] [--limit N] --json
cli-web-reddit user comments <username> [--sort hot|new|top] [--limit N] --json

Post Detail (no auth)

cli-web-reddit post get <url_or_id> [--sub <name>] [--comments N] --json

Fetches all comments including deeply nested threads (automatically expands "continue this thread" and collapsed comment chains via Reddit's morechildren API). Accepts full URLs, short IDs, or t3_ prefixed fullnames.

Auth

cli-web-reddit auth login     # opens browser, extracts token_v2
cli-web-reddit auth status --json
cli-web-reddit auth logout

Vote (requires auth)

cli-web-reddit vote up <thing_id> --json      # t3_xxx or t1_xxx
cli-web-reddit vote down <thing_id> --json
cli-web-reddit vote unvote <thing_id> --json

Submit (requires auth)

cli-web-reddit submit flairs <subreddit> --json                          # list available flairs
cli-web-reddit submit text <subreddit> <title> <body> [--flair ID] --json
cli-web-reddit submit link <subreddit> <title> <url> [--flair ID] --json

Use submit flairs first to get flair IDs when a subreddit requires flair.

Comment (requires auth)

cli-web-reddit comment add <thing_id> <text> --json
cli-web-reddit comment edit <thing_id> <text> --json
cli-web-reddit comment delete <thing_id> --json

cli-web-reddit me saved [--limit N] --json
cli-web-reddit me upvoted [--limit N] --json
cli-web-reddit me subscriptions --json
cli-web-reddit me inbox [--limit N] --json

Agent Patterns

# Get trending posts from a subreddit
cli-web-reddit sub top python --time week --limit 10 --json | jq '.posts[] | {title, score, url}'

# Search and get post details
cli-web-reddit search posts "fastapi tutorial" --limit 3 --json

# Check a user's activity
cli-web-reddit user posts spez --limit 5 --json

Notes

Public read commands work without auth (uses Reddit's .json API with curl_cffi)
Write operations (vote, comment, submit, save) require auth login first
Auth uses token_v2 cookie extracted via Playwright browser login
Token auto-refresh: when token_v2 expires (~15-30 min), the CLI silently launches a headless browser with the saved profile to refresh it — no manual re-login needed
HTTP 403 on specific endpoints (e.g., flair fetch on some subreddits) is correctly reported as "Permission denied" rather than "AUTH_EXPIRED"
Rate limits: ~60 requests/minute for public API, ~600/minute with OAuth
All commands support --json for structured output
