Capture a page as a PNG

Automatically capture a page as a PNG on reddit.com. Screenshot any URL (not limited to Reddit) at a pinned viewport width and pixel density, and save it to the machine's Downloads folder as a real browser download. Runs signed in when the target host has a session, so Reddit captures have no cookie banner and no logged-out login panel. fullPage:true captures the whole scrollable page for assets that need scrolling; pass clipHeight to bound a very long page. Returns the filename, size in bytes, image width and height, and the page title. Confirmed on reddit.com: capturing while signed OUT triggers Reddit's bot detection (tab gets detached non-deterministically); once the device is actually logged into Reddit, both fullPage and viewport-only captures are clean.

Input

url required

URL to capture.

filename required

Download filename, e.g. search-tall.png

fullPage optional

Capture the whole scrollable page rather than just the viewport.

Default: true
settleMs optional

How long to let the page settle before shooting.

Default: 4500
clipHeight optional

Optional CSS-px cap on captured height; useful when fullPage would be enormous.

viewportWidth optional

CSS viewport width to pin.

Default: 1280
viewportHeight optional

CSS viewport height to pin.

Default: 1000
deviceScaleFactor optional

DPR. 2 yields a 2x asset.

Output

bytes optional
title optional
width optional
height optional
filename optional

You do not need one. "Capture a page as a PNG" drives the real reddit.com pages in a browser, so it works whether or not reddit.com offers an API for this.
Required: url, filename. Optional: fullPage, settleMs, clipHeight, viewportWidth, viewportHeight, deviceScaleFactor.
It returns bytes, title, width, height, filename, loggedIn.
Yes. It acts as you on reddit.com: on your own Chrome it reuses your session, and on a Reduck-hosted browser it loads the reddit.com cookies saved by the Reduck extension.
It only reads. It looks things up on reddit.com and changes nothing there.

Get Reddit thread

Fetch a Reddit thread by its id or URL: the post (title, text, author, score, upvote ratio, comment count, type, link) and its comments in thread order, each with author, text, score, date, permalink and nesting depth. Needs a browser signed in to Reddit. By default it returns the first page of comments Reddit shows when the thread opens; set all_comments to expand every "more replies" and get the whole tree. num_comments counts deleted and removed comments too, so the list can be shorter than that number even when it is complete. sort picks Reddit's own comment order (best, top, new, controversial, old, Q&A).

Get subreddit threads

List a subreddit's threads by Reddit's native sort (best/hot/new/top/rising). "new" is chronological (filter with `since`); "top" takes a `time` window (hour…all); others paginate by `limit`. Returns url, title, author, score, num_comments, created, post_type, and body — the post's full text (never truncated; null for link/image posts). `limit` is a maximum, not a guarantee: fewer matching threads returns what exists.

Search Reddit

Search posts across all of Reddit (no subreddit restriction), with optional sort and time window. Returns count and threads (each with id, url, title, author, subreddit, score, num_comments, created, nsfw, preview_text). `limit` is a maximum: fewer matching posts than requested returns however many exist. Useful to discover which subreddits discuss a topic. The sort changes how relevant the results are: `top` orders Reddit's matches by score, and because Reddit matches loosely, a heavily upvoted post only tangentially related to the query can outrank the genuine matches. That is Reddit's own ranking, returned as-is. Use the default `relevance` sort when on-topic results matter, and treat a non-zero count under `top` as "Reddit returned something", not as proof the posts are about the topic. Reddit refuses connections from datacenter addresses, so this works as-is on your own browser; on a hosted cloud browser the session has to be given a country so it exits through a residential address, otherwise Reddit blocks it and the script says so.
