Frequently Asked Questions

Is it really free?

Yes. When you sign up you won't be asked for payment information at all.

That said, if you want to support F5Bot's development, as of 2024, some paid features are also now offered.

Why is it free?

I made F5Bot so I could use it myself. After a couple months of usage, I decided to share. It doesn't cost much to put it up for everyone to benefit.

What sites are monitored?

Currently Reddit, Hacker News, and Lobste.rs.

How can I limit my results to a few subreddits?

You can use the only-url flag to specify which subreddits to monitor. You can use this flag multiple times. For example, to only get results from the /r/news and /r/worldnews subreddits, you would use these flags:

only-url=/r/news only-url=/r/worldnews

Why am I getting results from all of Reddit? My flags are only-reddit only-url=/r/mysubreddit.

This is because a match is valid if any of the only- flags apply. Since you have only-reddit, it matches everything on Reddit.

To fix this, simply remove the only-reddit flag. Your alert will then correctly only match content from the URL you specified.

For a more detailed explanation, please see Understanding "only-" Flags.

Does it look at comments too?

Yes. F5Bot scans both submissions and comments. See here for more info.

Are keywords/phrases case-sensitive?

No. Keywords and phrases will match regardless of capitalization.

Can it let me know when my website is submitted?

Yes. You can enter a partial URL as a keyword to track. Make sure you do not use the "whole" flag.

How can I test that it works?

You can post your keyword or phrase on Reddit in the test subreddit. You should expect an email from F5Bot a couple minutes after you do.

What are the limits?

Each account is allowed a maximum of 200 keywords. If you need more than that, you can upgrade to a paid tier from the "Account" tab. Please don't create multiple accounts to subvert the limit.

Additionally, if a keyword is hit more than 50 times in a 24 hour period, it will be disabled. You can manually re-add the keyword from your account. Keep in mind that 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.

You can upgrade to a paid tier, and I will increase your daily hits limit to 1,000.

See here for more info on paid tiers.

How often does F5Bot check for new content?

F5Bot checks for new content every few minutes. After a post or comment appears on a monitored site, you can typically expect an alert within a few minutes.

What are semantic alerts?

Semantic alerts use AI to match content based on a natural language description instead of exact keywords. You describe what you are looking for, and the system evaluates new content against your criteria. This is an Ultra tier feature. See the Semantic Alerts Documentation for details.

Can I get alerts in Slack or Discord?

Yes. Paid users can configure webhook URLs to have alerts posted directly into Slack or Discord channels. You can set this up from your account page.

Can I monitor a specific Reddit user?

Yes. Power Users can use the in-username flag to match only on the author's username. See the Power User Documentation for details.

How do I exclude certain subreddits?

You can use the no-url flag to skip results from specific subreddits. For example, to exclude /r/politics and /r/news, you would use these flags:

no-url=/r/politics/ no-url=/r/news/

Why did I get a match that doesn't seem to contain my keyword?

F5Bot searches submission titles, URLs, and comment bodies. Your keyword may have matched in the URL or title even if it doesn't appear in the body text. If you want to limit where your keyword is searched, Power Users can use the in-title, in-body, or in-url flags. See the Power User Documentation for details.

Can I get alerts via RSS or JSON instead of email?

Yes. Power Users and above can access personalized RSS and JSON feeds of their alerts. You can find your feed URLs on your account page. See the Power User Documentation for details.

Can I use regex or wildcards?

No. F5Bot does not support regular expressions or wildcards. Keywords are matched exactly as entered, including any special characters. See the keyword documentation for more info.

What happens to my alerts if I cancel my subscription?

Your alerts will remain on your account, but any alerts using paid features (such as Power User flags) will stop generating matches until you resubscribe.

How do I stop getting emails without deleting my alerts?

You can disable individual alerts from your dashboard by toggling them off. Paid users also have the option to set their email delivery to "Don't send emails" from their account page, which lets you receive alerts only via RSS, JSON, or webhooks.

Can I combine multiple alerts into one email?

Yes. Power Users can use the group=name flag to organize alerts into groups. All alerts with the same group name will be bundled into a single email, separate from your other alerts. See the Power User Documentation for details.

Can I get a daily email at a specific time instead of instant alerts?

Yes. Power Users can choose scheduled email delivery from their account page. You can set up to 3 delivery times per day and choose which days of the week each time slot applies to. See the Power User Documentation for details.

Can I add keywords in bulk?

Yes. Power Users can use the mass upload feature to add, update, or delete keywords in bulk by uploading a CSV file.

Why was my keyword rejected for being too common?

Free accounts cannot monitor very common words or phrases. If your keyword is rejected, you can upgrade to a paid tier, which removes this restriction.

What does the "whole" flag do?

The whole flag makes your keyword match only on whole words or phrases. Without it, a keyword like "thing" would also match "something" or "thingy". With the whole flag, it will only match when "thing" appears as a complete word. See the keyword documentation for more info.

Can I monitor posts but not comments (or vice versa)?

Yes. Use the no-comments flag to only get posts, or the no-posts flag to only get comments. See the keyword documentation for a full list of flags.

Can I advertise with F5Bot?

Yes. F5Bot offers small text ads in alert emails. See our advertise with F5Bot page for details.

Will you support more sites in the future?

Maybe. Let me know if you have any ideas.
