What are you all using for invoicing now?
We moved our agency's billing to Fernly last month. Recurring invoices just work, but does Fernly handle different due dates per client?
Community mention alerts
Know the moment someone mentions your product.
Keyword Sonar watches Reddit, Hacker News, Bluesky, Mastodon, Stack Exchange, GitHub, forums and the open web for your product, your competitors and the problem you solve, and sends you the link while the thread is still alive.
How it works
Set up once, then let the alerts come to you.
Name what to watch
Your product, a competitor, or the problem you solve. Google-style syntax: phrases, OR, exclusions, title-only. Narrow it to the subreddits, forums or repos that matter.
Preview before you rely on it
See what the watch would have caught in the last 7 to 90 days, per day and per source, and tune it until the matches look right.
Get the link where you work
Email right away, hourly, every 6 hours or as a daily digest. Slack, Discord, RSS and webhooks on Standard and Pro.

Questions
What counts as a result?
One new post or comment matched by one watch. Results count toward your daily quota when they're stored, and quotas reset at 00:00 UTC. We tell you in the app, and in your next digest, whenever a limit is reached. Nothing is dropped silently.
Where do you look?
Reddit, Hacker News, Bluesky, Mastodon, curated Discourse forums, Stack Exchange, GitHub, DEV, Lobsters, Indie Hackers and the open web. The Sources section on this page shows the measured latency and current status of every source, including the ones still waiting on access.
Why is it so cheap?
Collection is shared: we read each source once and match every new item against every watch. The marginal cost of your watch is close to zero, so we don't need to charge $29.95 for it.
Do I need a card for the trial?
No. You get 14 days of Pro. When the trial ends your watches pause, your results stay viewable, and you can subscribe at any time to resume.
What data do you collect?
Only public content a logged-out visitor can see. We never log in, never bypass rate limits, and we honor opt-outs and takedown requests. Keyword Sonar is for brands, products and topics, not for monitoring private individuals.
Can I cancel anytime?
Yes, from Plan & billing. Access continues to the end of the paid period. There's no commitment on monthly billing.
