The 8 best F5Bot alternatives in 2026

Updated 21 August 2026 · figures checked against each vendor's own pricing page

F5Bot has run since 2017 and it does have a free tier, but that tier is 5 keywords, 20 alerts a day and a two-hour delay, with ads in the emails and no keyword filtering — F5Bot marks it personal use only. Doing real work on it means paying: filtering from $9.99, Slack and relevance filtering from $49.99, webhooks and the API from $214.99. People leave once a busy keyword starts hitting its daily cap and switching itself off, or once the sorting takes longer than the reading. This page ranks eight alternatives against those reasons, with every price read off the tool's own pricing page.

Redwatcher is a Reddit monitoring tool that scores every keyword match for relevance before it alerts you. It is one of the eight, and it is ours.

The best F5Bot alternatives, one by one

Ranked on how much work each one takes off you. A keyword alerter that forwards every match moves the sorting problem into your inbox. A tool that scores each match first does the sorting for you. That is the difference the ranking is built on, and it is why the order runs the way it does. Prices for the other tools were read from their own pages on 17 August 2026.

1. Redwatcher — every match scored 0 to 100 before it is sent, on every plan, from $19
2. Syften — rules you write, results metered per day, from $29.95
3. SubWatch — keyword forwarding with no scoring, $9
4. SubLookout — keyword forwarding with no scoring, ten-minute checks, $12
5. Prowlo — built for an agent to query, hourly, $19
6. Octolens — $159 for ten keywords, and $10 for each one after
7. Brand24 — a general media suite at $249, shallow on subreddits
8. Google Alerts — no cost, no scoring, and it misses Reddit comments

Redwatcher

Reddit only · scoring on every plan

$19$39$99

Scores every match from 0 to 100 before it becomes an alert, shows the reasons on the thread, and holds back everything under your bar.

What you get

• Relevance scoring on every plan from $19, on every match, with no filter to write and no usage billing
• No cap on alerts per keyword, so a busy brand name never switches itself off
• Every match carries its reasons, and a wrong score is corrected in one click and applied to future matches
• Email, Slack, Telegram and webhooks on every tier, with unlimited seats
• Separate projects for separate brands or clients, up to 10
• Five-minute checks on every plan, not sold as an upgrade

2

Syften

Reddit · Hacker News · forums

$29.95$49.95$119.95

Rule-based filtering across Reddit, Hacker News and forums.

Where it falls short

• No relevance score on any tier. You write and maintain the rules yourself, and a rule cannot tell you why a thread is worth answering
• Results are metered per day: 100 on entry, 200 in the middle, 500 at the top. A busy watchlist runs out before the day does
• The entry tier carries three filters, so covering a brand, a category and two competitors already pushes you up a plan
• Starts at $29.95, above Redwatcher's $19, for less filtering

3

SubWatch

Reddit only · regex and SMS

$9/mo$49 lifetime

Keyword forwarding with regex matching and SMS delivery.

Where it falls short

• No relevance scoring, so every match still lands on you to sort. The reason you left F5Bot follows you
• Reddit only, with no scoring to compensate
• The $49 lifetime price is a bet on the tool still being maintained in three years
• No projects, so two brands or two clients share one list

4

SubLookout

Reddit only · 10 monitors

$12

Keyword forwarding across a fixed number of monitors.

Where it falls short

• No relevance scoring
• Ten-minute checks, twice as slow as Redwatcher's five
• Capped at 10 monitors of 20 subreddits and 20 keywords, so the ceiling arrives early
• Reddit only

5

Prowlo

MCP server · semantic search

$19

A read-only data endpoint for agents rather than an inbox for a person.

Where it falls short

• Hourly watchers, against five-minute checks here. On Reddit an hour is several hundred comments
• No inbox to work through, so there is nothing to hand a colleague
• You need an agent set up to query it before it does anything at all
• No scored queue, no held-back count, no reasons attached to a match

6

Octolens

13+ platforms · MCP

$159$499

Broad platform coverage with speed sold as a tier.

Where it falls short

• $159 for ten keywords, against 100 keywords for $19 here, then $10 for every extra keyword
• Real-time is a $499 tier. The tier below it is hourly
• Spread across 13 platforms, so the depth on any single subreddit is thinner
• Far past what anyone leaving a $9.99 plan is looking to spend

7

Brand24

Full media monitoring suite

$249$199 annual

A general media monitoring suite that includes Reddit among many sources.

Where it falls short

• $249 a month, thirteen times Redwatcher's entry price
• Reddit is one source among many, so subreddit-level control is shallow
• Built for a marketing department to report with, not for someone acting on a thread today
• No per-thread relevance score of the kind this list is ranked on

8

Google Alerts

Free · web-wide

Free

Web-wide alerting built on the search index.

Where it falls short

• It reads indexed pages, so Reddit comments do not reliably reach you at all
• No subreddit control, no scoring, no team routing
• Delivery is slow enough that a live thread has usually moved on
• No way to separate one brand from another

Which F5Bot alternative to pick

Redwatcher, unless one of two things applies.

If you need Hacker News or Lobsters as well as Reddit, no Reddit-native tool covers them, and that includes this one. And if you are running a personal project on five rare keywords, F5Bot's free tier already fits — it is capped at 20 alerts a day with a two-hour delay and no filtering, which is enough when almost nothing matches.

Everything else on this list forwards matches without scoring them, meters what it sends, or costs several times more for less. The sorting still ends up on your desk.

Where F5Bot stops

Every plan caps how many alerts a single keyword can send in a day — 10 on the free tier, 30 on Silver, 100 on Gold, 500 on Platinum — and a keyword that goes over the cap is disabled until you switch it back on. F5Bot's own FAQ puts it plainly: "F5Bot is designed to alert you about fairly uncommon keywords or phrases. If you're trying to monitor a very popular brand, this might not be the right tool for you."

Relevance filtering starts at $49.99, is capped at two filters, and bills token use above $10 a month on top of the plan. Webhooks and the API start at $214.99. The free tier has no keyword filtering at all, no full post text, and ads in the emails. Tier by tier, that detail is in our F5Bot comparison.

Questions about F5Bot alternatives

What is the best F5Bot alternative?

Redwatcher, from $19 a month. It is the only tool in this comparison that scores every match from 0 to 100 before it sends anything, on every plan, with the reasons attached and no usage billing. The others forward matches and leave the sorting to you, meter how many they will send in a day, or cost several times more for less control.

Is there a free F5Bot alternative?

Nothing free does the job, including F5Bot's own free tier — 5 keywords, 20 alerts a day, a two-hour delay, ads, and no keyword filtering, which F5Bot marks personal use only. Google Alerts costs nothing but reads indexed pages, so Reddit comments do not reliably reach you. The cheap paid tools forward every match without scoring it, which is the same sorting problem at a lower price. Redwatcher runs seven days without a card, then $19 a month.

Which F5Bot alternative is cheapest?

A few tools sit under $15, but none of them score matches, so they solve price rather than the problem. Measured per useful alert rather than per month, Redwatcher's $19 covers 100 keywords and 25 subreddits with scoring on every match, where $159 elsewhere buys ten keywords.

Which F5Bot alternatives cover Hacker News?

Hacker News and Lobsters are outside the scope of every Reddit-native tool here, Redwatcher included. If those two sites are the reason you are looking, this comparison is not the one to read. If Reddit is where your buyers are, scoring matters more than site count.

Do any of these post replies for you?

None of the eight on this page do. Tools that post on your behalf are a separate category with a public ban history behind it, and they are deliberately not listed here.

Which F5Bot alternatives have relevance scoring?

Of the eight compared here, Redwatcher scores every match from 0 to 100 on every plan and shows the reasons. Syften and the cheaper tools filter with rules you write, which tells you a thread matched but not whether it is worth answering. Octolens and Brand24 carry their own filtering at $159 and $249. F5Bot's own AI filtering starts at $49.99 and is capped at two filters, with token use billed above $10 a month.

Do F5Bot alternatives monitor Reddit comments as well as posts?

The Reddit-native tools here do, and it matters more than it sounds: most of what gets said about a product on Reddit is said in comments rather than posts. Google Alerts is the exception, because it reads indexed pages and comments are not reliably indexed.

How much do F5Bot alternatives cost?

The range across this comparison is $0 to $499 a month. Redwatcher is $19, $39 and $99 with every feature on every tier. The sub-$15 tools do no scoring. Octolens starts at $159 for ten keywords and charges $10 for each keyword after that, and Brand24 is $249. Every figure was read off the vendor's own pricing page in August 2026.

Why is Redwatcher first on this list?

Because the list is ranked on how much work each tool takes off you, and it is the only one that sorts matches before they reach you. Every other tool on this page forwards what it finds and leaves the judgement to you, which is the job people leave F5Bot to stop doing. We publish the criterion so you can check the ranking against it.
