Zapier vs emit for RSS → Slack
The classic Zapier recipe — RSS trigger, Slack action — works, but every delivered item is a task against your plan, and the interesting part (deciding which items are worth posting) is on you. emit does RSS → Slack/Discord/Teams/Telegram/Google Chat with 250 deliveries a month free, then $1.60 per 1,000, adds an LLM relevance filter you configure in plain English, and creates the feed too when the site doesn't have one. The same applies to the other classic recipe — RSS trigger → “Webhooks by Zapier” — which is a single sink here, on the same 250-free allowance and $0.0016 per delivery after it instead of one task per item.
| emit | Zapier (RSS → Slack) | |
|---|---|---|
| RSS → Slack/Discord/Teams/Telegram/Google Chat | 250 deliveries/mo free, then 1 credit ($0.0016) each | 1 task per delivered item; Free = 100 tasks/mo |
| RSS → your own endpoint (JSON) | Same allowance. JSON sink POSTs each item, or one daily/weekly batch that counts as one delivery | Webhooks by Zapier — 1 task per delivered item |
| Cost at ~20 items/day | ~350 paid deliveries ≈ $0.56/mo | ~600 tasks/mo → Professional plan, from $19.99/mo |
| Filtering | Plain-English LLM filter (1 credit per 5 items ≈ $0.19/mo here) | Keyword filters free; AI steps consume extra tasks |
| Site has no RSS feed | Built in — emit watches the page itself | Needs a separate feed-generator tool first |
| Polling | Every few minutes (sinks) / hourly+ (smart feeds) | 15 min free · 2 min Professional · 1 min Team |
| Email digest output | Built in, from your own domain | Compose it yourself from actions |
| Everything else Zapier does | No — emit is feeds in, feeds out | 8,000+ app integrations |

Why people pick emit for feed automation
- RSS → chat shouldn't need an automation plan: the first 250 pushes a month are free, and each one after costs $0.0016, not a task.
- The filter is the product: "only security advisories, not marketing" is one sentence here and a project in Zap steps.
- Feedless pages work out of the box — no second tool to generate the feed first.
- Delivering to your own code is the same primitive, at the same price, as delivering to Slack — a JSON webhook with digest batching (a digest counts as one delivery), not a task.
When Zapier is the better choice
When the feed is just one input among many and the output isn't chat/email/webhook — if new items must create Trello cards, update Sheets, and text your phone, Zapier's 8,000 integrations are the point. (You can also do both: emit filters the feed, Zapier consumes emit's clean RSS output as its trigger — fewer items, fewer tasks.)
