RedditAlert is an AI-powered Reddit monitor that emails you within 30 seconds, matching posts and comments by plain-English prompt, regex, or boolean query, and it can draft a reply. Its plans run free to $129 a month. Redditapis watches all of Reddit for a keyword or a named subreddit and pushes each match to a webhook, Slack, or Discord on every paid tier from $19/mo, built on a full Reddit data API.
RedditAlert or Redditapis: which should I use for Reddit monitoring?
Both are Reddit-native monitors. Use RedditAlert when an email alert is the whole job: it runs AI prompt matching that reads intent, adds regex and boolean queries, drafts a reply for you, and covers posts and comments across all of Reddit, priced free to $129 a month, all delivered by email within a claimed 30 seconds. Use Redditapis when the alert has to reach code: webhook, Slack, and Discord delivery on every paid tier from $19 a month, per-subreddit and per-author filters, HMAC-signed webhooks retried for up to 21 minutes, and a 59-endpoint Reddit data API underneath so the same account can also search, write, vote, and DM. RedditAlert is at or faster than us on latency, so choose on delivery channel and data access, not speed.
Side by side
RedditAlert figures read from redditalert.com and its pricing page on 2026-09-15, plus its published API schema. Redditapis figures match this site's pricing and monitoring pages.
| Dimension | RedditAlert | Redditapis |
|---|---|---|
| What it covers | Reddit only. It watches posts and comments and matches them by AI prompt, regex, or boolean query, then emails you the match with a link | Reddit only, with subreddit, author, score, keyword, and domain filters purpose-built for it, delivered to a webhook, Slack, or Discord |
| Alert delivery | Email, and email only. Alerts land in your inbox within 30 seconds, each with a direct link, and every match is kept in the dashboard. There is no Slack, Discord, or webhook option on any tier | Webhook, Slack, and Discord delivery on every tier, including the free watch. Paid plans start at $19/mo, and the alert can reach code rather than an inbox |
| Pricing model | Four tiers metered by alert count and monthly email volume: Free (2 alerts, 25 emails), Personal $19/mo (10 alerts, 500 emails), Professional $49/mo (20 alerts, 1,000 emails), Small Team $129/mo (60 alerts, 3,000 emails). Annual billing is 2 months free | $19 to $199/mo flat by monitor slot (15 to 500 monitors), no email cap and no per-match charge. A quiet month and a busy month cost the same |
| Free tier | Free forever, no card: 2 alerts across 2 subreddits, 25 alert emails a month, plus 3 Reddit searches and 3 subreddit-finder runs. Email only. If email is enough and 25 alerts a month covers you, this is free and we are not cheaper | One free watch on every account, no card: 1 keyword across all of Reddit, new posts, checked about every 60 seconds, delivered to a webhook, Slack, or Discord. Naming a subreddit, comment matches, and extra watches start at $19/mo |
| Matching | AI prompt matching that reads intent rather than exact words, plus regex and nested boolean (AND, OR, NOT) on every tier. It can also draft a reply for you to edit and post. This is genuinely more matching intelligence than we run today | Keyword, subreddit, author, score, and domain filters built for Reddit. We run no AI matching step and draft no replies today; instead every match arrives as structured JSON you can feed to your own model for scoring or reply drafting |
| Posts vs comments | Posts and comments on every tier, including sitewide across all of Reddit | Posts on every tier. Comment matches from Growth, $49/mo, and a comment monitor has to name at least one subreddit. Sitewide watches stay post-only, because the all-of-Reddit comment listing runs at roughly 100 comments a second and we will not sell what we cannot poll |
| Coverage per dollar | Metered by alerts and subreddits: 2 subreddits free, 10 on Personal $19, 20 on Professional $49, 60 on Small Team $129 | 15 monitors across 10 subreddits on Starter $19, 50 monitors across 25 subreddits on Growth $49, 200 across 50 on Pro $99, and 500 across 100 on Scale $199. More monitors per dollar at every matching price rung |
| Programmatic access | A published REST API that manages your alerts and collections. Its schema at api.redditalert.com has no endpoint that returns a raw Reddit post, comment, user, or subreddit, so you can automate RedditAlert itself but not build on Reddit data with it | Built on the full 59-endpoint Reddit REST API: search, comment search, users, communities, write, vote, and DM, on every tier, billed a flat $0.002 a read |
| Delivery guarantee | Not published on their pricing or docs pages. Delivery is by email, so retry and receipt behaviour is whatever your mail provider does | HMAC-signed webhook POST, retried with backoff for up to 21 minutes. A delivery records its attempt count and last error, so a gap is queryable rather than silent |
| Detection speed | Real-time, with email alerts claimed within 30 seconds of a matching post or comment | Poll floors of 60 seconds on Starter and 30 seconds from Growth up. Those are the fastest a tier is allowed to poll. RedditAlert's sub-30-second claim is at or below our own measured latency, and we do not claim to be faster |
| Result volume | Metered by monthly email count: 25 on Free, 500 on Personal, 1,000 on Professional, 3,000 on Small Team. Past the cap you buy the next tier | A daily alert ceiling per monitor: 10,000 on Starter, 25,000 on Growth, 50,000 on Pro, 100,000 on Scale. Over the ceiling, matches are still recorded, the count resets at midnight UTC, and the price does not move with match volume |
Redditapis monitoring runs on top of the 59 REST endpoints in the Redditapis OpenAPI spec at docs.redditapis.com/openapi.json. Compare tiers on the pricing page.
Neither tool wins every row. RedditAlert is the stronger standalone alert product; Redditapis is the stronger pipeline input. The real question is where the alert has to go.
RedditAlert friction
Redditapis
How it works
Register a webhook, Slack channel, or Discord channel, and matches arrive as a signed POST instead of an email you have to triage. Name a subreddit to watch that community, or send a keyword with no subreddit at all and it watches every new post on Reddit:
curl "https://api.redditapis.com/api/monitor/add" \
-H "Authorization: Bearer YOUR_API_KEY" \
-d '{"q":"your brand"}' # no subreddit: all of RedditAdd "subreddit":"SaaS" to scope that same monitor to one community instead. Full endpoint paths and parameters live in the API docs. See the full monitoring product on the Reddit monitoring API page.

A comparison page that only lists the other tool's weaknesses is not worth reading. RedditAlert runs an AI prompt matcher that reads the meaning of a post rather than exact words, it drafts a reply for you to edit and post, and it covers comments across all of Reddit on every tier. Redditapis does none of those three today: we run no AI matching step, we draft nothing, and our sitewide watches are post-only. If any of those is the job, RedditAlert is the better tool and this page will not pretend otherwise.
Per our own delivery logs, the busiest single monitor we have ever run peaked at 2,091 alerts in one day, which is the number our per-monitor daily ceilings are set from: 10,000 on Starter climbing to 100,000 on Scale, every rung well clear of that observed peak. A monthly email cap answers the same question differently. RedditAlert's free tier sends 25 alert emails a month and Small Team sends 3,000, so a genuinely busy keyword is bounded by the tier rather than recorded and shown to you the way an over-ceiling match is here.
A webhook delivery is not fire and forget. Each one is HMAC-signed and records its attempt count, the time of its next retry, and the last error the receiving endpoint returned, with backoff for up to 21 minutes. If the endpoint stays unreachable for the whole retry chain, the delivery is marked dead rather than quietly dropped, so a gap in your alerts is something you can query afterwards instead of infer. An email-only monitor hands that state to your mail provider and keeps none of it.
RedditAlert's AI does the reading and its email tells a person the result. That is the right shape when a person acts on it. When code has to act, the same email cannot be the trigger without someone parsing inboxes, and it cannot hand your program the subreddit, the thread id, the score, or the surrounding comments as fields. A Redditapis match arrives as one structured JSON object carrying the full post or comment text, author, subreddit, score, permalink, and timestamp, which is exactly the input an AI step like RedditAlert's needs, handed to your model instead of bundled into a product.
Both tools serve the same three jobs, and the right choice still comes down to whether a person or a program acts on the alert. These are the buyers who show up in this category, and what each of them actually needs from a monitor before picking.
Founders and SaaS teams watch for people asking for a tool like theirs, or complaining about a competitor, so they can join the thread early. RedditAlert drafts the reply for you; Redditapis routes the match to Slack or a webhook so the whole team sees it and code can log it against a pipeline.
Product and brand teams track mentions of the company across Reddit to catch complaints and questions before they spread. If a human triages an inbox, RedditAlert fits. If the mention has to open a support ticket or fire a Slack alert to an on-call channel, Redditapis delivery reaches those systems.
Community and demand-generation teams look for threads worth replying to inside a set of named subreddits. RedditAlert adds AI intent matching and a drafted reply for this job. Redditapis gives per-subreddit and per-author filters and, on the same account, the write and DM endpoints to act.
Keyword alerts help, but they are not everything, and it is worth stating our gaps plainly. Redditapis runs no AI intent matching step and drafts no replies, so RedditAlert's AI reply suggestions have no counterpart here today. Our comment monitors must name a subreddit and our sitewide watches are post-only, so all-of-Reddit comment coverage is a RedditAlert strength we do not match. And we do not claim to be faster: RedditAlert's sub-30-second email is at or below our own measured latency. If any of those is the deciding factor, RedditAlert is the better tool.
RedditAlert can read a matching thread and draft a first reply for you to edit and post, which is a real time-saver when a person is doing the replying. Redditapis draws a hard line before that step: we deliver the full match as structured JSON and stop, so the reply, the tone, and the model are yours. The same webhook that alerts you can pipe the post straight into your own LLM for a draft, which is the identical AI step handed to your stack instead of bundled into the price.
Both tools keep a running record of what matched so you can see who is talking about you. RedditAlert keeps every alert in its dashboard alongside the emails it sent. Redditapis exposes each monitor's health view, where you can review the feed of recent matches, see the daily alert count against the ceiling, and read exactly what was held back once a monitor passes its per-day limit rather than being left to guess at a silent gap.
RedditAlert is not the only name you will meet while comparing. A comparison page owes you the rest of the field rather than quietly omitting tools you will find recommended elsewhere.
The free keyword bot that watches Reddit, Hacker News, and Lobsters and emails you. Email-only like RedditAlert, with no AI matching, and Slack, Discord, and its API sit on higher tiers. See the full F5Bot comparison.
KWatch.io is a multi-platform keyword monitor that covers Reddit alongside other social sources and delivers to Slack and email. Broader than Reddit alone, which is useful if Reddit is one channel among several and a burden if it is the only one you care about.
A broad brand-monitoring suite covering social, news, and the web with sentiment and reporting, where Reddit is one lane inside it. Stronger on analytics and priced for it; if Reddit is your only source you are paying for coverage you will not use.
Mention is a media-monitoring platform for brands that tracks the web and social including Reddit, aimed at marketing teams who want one dashboard for everything. Like Brand24, Reddit is a component rather than the product, so a Reddit-native tool goes deeper on the one source.
Two questions come up on almost every monitoring comparison, so here are the direct answers before the full FAQ below.
No third-party monitor can, and that is a Reddit limit rather than a tool one. Reddit's API does not expose the content of private or quarantined subreddits to outside applications, so Redditapis and RedditAlert both watch public subreddits and public comments only. If a community is private, neither tool can see inside it.
Often, yes, which is why early replies matter. Google indexes Reddit threads and AI answer engines quote them, so a helpful reply posted while a thread is young keeps returning value as that page ranks. A monitor that reaches you fast, by email or by webhook, is what puts you in the thread early enough.
A Reddit-native keyword and subreddit monitor with webhook, Slack, and Discord delivery on every paid tier, and an alternative to RedditAlert for teams that need the alert to reach code rather than an inbox.
Reddit monitoring from $19 a month for 15 monitors, webhook, Slack, and Discord delivery included on every paid tier.
Listed price: $19.00.
RedditAlert is an AI-powered Reddit monitor that watches posts and comments and emails you within 30 seconds when your terms appear. It matches by plain-English prompt, regex, or boolean query and can draft a reply. Its tiers are Free for 2 alerts, Personal $19, Professional $49, and Small Team $129 a month.
For teams that need the alert to reach code, Redditapis. It watches named subreddits or all of Reddit with author, score, and keyword filters and pushes each match to a webhook, Slack, or Discord on every paid tier from $19 a month, where RedditAlert delivers by email only and adds no webhook on any plan.
Use RedditAlert when an email alert with AI intent matching and a drafted reply is the whole job, and comment coverage across all of Reddit matters. Use Redditapis when the alert has to reach Slack, Discord, or a webhook, when you want per-subreddit and per-author filters, and when the same account should also call a full Reddit data API.
No. RedditAlert delivers by email on every tier, from Free through Small Team at $129 a month, plus a dashboard log of matches. There is no Slack, Discord, or webhook delivery on any plan. Redditapis includes webhook, Slack, and Discord delivery on its cheapest paid tier at $19 a month.
Four tiers. Free for 2 alerts and 25 emails a month, Personal $19 for 10 alerts and 500 emails, Professional $49 for 20 alerts and 1,000 emails, and Small Team $129 for 60 alerts and 3,000 emails. Annual billing gives 2 months free. Figures are from redditalert.com/pricing.
RedditAlert claims email alerts within 30 seconds, which is at or below our own measured detection latency, so we do not claim to be faster. Redditapis poll floors are 60 seconds on Starter and 30 seconds from Growth up. If raw speed is the deciding factor, treat the two as comparable and choose on delivery and data access instead.
Yes, with Redditapis. Monitoring sits on top of the same 59-endpoint Reddit REST API used for search, comment search, user and community lookups, and write actions, so the same account that watches keywords can also pull historical data, reply, vote, or DM over one authenticated API. RedditAlert's API manages your alerts, not Reddit data.
Not today. Redditapis runs no AI intent step and drafts no replies. Every match arrives as structured JSON carrying the full post or comment text, author, subreddit, score, and permalink, so you can pipe it into your own model for lead scoring or reply drafting. RedditAlert bundles the AI step in; Redditapis hands you the input for yours.
