}Run of version 0.1.3 on Hacker News and Lobsters, 11 Oct 2026. The headline is quoted from both feeds, and the row keeps the link to the original.
Who it is for
If you send a daily digest or newsletter. 20 to 200 sources, each story once.
If you watch a brand or a topic. Keep only stories with your words, drop the ones with words you do not want.
If you feed an automation. New stories go to Zapier, Make or n8n by webhook.
How it works
Two items are one story when their links match after cleanup or their headlines have the same words.
Numbers must match, so Rust 1.90 and Rust 1.91 stay apart.
Stories covered by more sources come first, then the newest.
What it costs
$0.001 per feed and per story, plus $0.005 per run.
- Merge 20 feeds into one digest of about 340 stories
- about $0.37
- The same 20 feeds every hour, only new stories (about 5)
- about $0.03 per run
Never charged: Broken feeds and repeated stories are never charged.
What it will not do: It reads only the feeds you give it. It never opens article pages.
A broken feed never stops the run.
What's new
0.1.5, released 13 Oct 2026
Changed- Pricing: the $0.005 start fee is now Apify's standard “Run started” event (apify-actor-start), charged by Apify when a run starts. The price per run is unchanged, but the fee is now also charged when a run starts and then stops on an input the tool cannot use (for example an unreadable “Published after” date). Before, such runs were free. Inputs that Apify rejects before starting a run (for example an empty feed list) still cost nothing.
- Runs use at most 1 GB of memory, so the start fee is always charged exactly once per run. 500 feeds with 50 items each need under 400 MB.
- The Store page now has a 3-step guide, two pricing examples (one-off digest and hourly monitoring) and an FAQ.
Fixed- sourceCount no longer counts one publisher twice when feeds spell its name in different case (for example “Wired” from Bing News and “WIRED” from Google News), so such stories no longer jump above newer ones in the ranking. Every feed is still listed in sources.
0.1.3, released 11 Oct 2026
Fixed- Google News and Bing News feeds: the same headline from different publishers (for example “... - Yahoo” and “... - FOX 10 Phoenix”) is now one row instead of several.
Changed- For Google News, Bing News and other feeds that name the original publisher, source now shows the publisher (Reuters, Yahoo) instead of the search feed name, and sourceCount counts publishers.
Added- New feedTitle field on every row and in sources, with the name of the feed the story came from.
0.1.2, released 11 Oct 2026
Added- Merge any number of RSS 2.0, Atom, RDF (RSS 1.0) and JSON Feed URLs into one ranked digest. Gzipped feeds, redirects, relative links and non-UTF-8 feeds work out of the box.
- The same story from different feeds becomes one row with every source listed (sources, sourceCount), even when the links carry tracking parameters, AMP versions or trailing slashes, or the headlines differ by an “Updated:” prefix, punctuation or word order.
- Stories covered by more sources rank first, then the newest.
- Include and exclude keywords (whole words, case and accent insensitive, any language).
- Only new items on scheduled runs, with a separate memory per digest (stateKey), kept for 30 days.
- Webhook alert with the new stories as JSON.
- Optional duplicate rows (dupOf) and full feed content.
- A broken feed adds a free feed-error row with the reason, and the run continues.
- A feed URL pointing at a private, loopback or cloud-metadata address gets a feed-error row instead of being fetched; the same check applies to the webhook URL, reported in the run summary. The webhook URL is stored as a secret input.
Privacy
It reads only the public feeds you list.
Runs, results and storage stay in your own Apify account.
Questions
How does it decide two stories are the same?
When their links point to the same page after tracking tags, AMP and trailing slashes are removed, or when their headlines have the same words in any order. Headlines more than 7 days apart are never merged.
Does it work with Google News feeds?
Yes. The same headline from different publishers becomes one row, and each publisher is counted as a source.
How do I get only new stories on a schedule?
Keep 'only new' on and give the digest a name. Each scheduled run returns only stories you have not received in the last 30 days.
Can it send stories to Zapier, Make or n8n?
Yes. Give a webhook address and new stories are sent to it as JSON.
Do keyword filters match parts of words?
No. Whole words only, so rust does not match trust. Case and accents are ignored, in any language.
What happens when a feed is down?
That feed gets a free row with the reason, and the run continues with the others.
