F5Bot and repco both monitor Reddit, but they're built for different goals. F5Bot is a free service that emails you when your keyword appears on Reddit or Hacker News. repco is an AI sales rep that watches Reddit and LinkedIn, classifies intent, drafts a contextual DM, and sends from your account.

F5Bot is the cheapest possible Reddit-monitoring entry point ($0). repco is a complete intent-to-meeting motion. Here's the head-to-head and when free is enough vs when it isn't.

Key takeaways

• F5Bot is a free email-alert service that notifies you when keywords appear on Reddit or Hacker News.

• repco is an AI sales rep that monitors Reddit and LinkedIn for buying intent, classifies on a 1-10 scale, drafts contextual DMs, and sends via Browserbase.

• F5Bot has zero cost, zero classification, zero outreach. You read emails and act yourself.

• repco at Free Forever is also $0 with monthly credits and includes the action layer.

• Common pattern: start with F5Bot for keyword alerts, upgrade to repco when manual processing becomes the bottleneck.

What is F5Bot?

F5Bot is a free service from a solo developer that sends you email alerts when your defined keywords appear in new Reddit posts/comments or Hacker News posts. You set keywords, F5Bot scans every few minutes, you get an email per match. No web app, no UI to speak of, just emails.

The trade-off: F5Bot is keyword-match only. There's no intent scoring, no context summary, no DM drafting, no sending. It's a notification firehose, the operator does everything downstream.

What is repco?

repco is an AI sales rep that finds buyers asking for what you sell on Reddit and LinkedIn. Claude Sonnet 4.6 classifies each detected post on a 1-10 intent scale. The agent drafts a 3-sentence DM referencing the specific post, then executes via Browserbase.

Side-by-side comparison

When F5Bot wins

1. You want zero cost. F5Bot is free with no upsell. If your keyword volume is low (5-20 matches/day), the email firehose is manageable.

2. You want Hacker News coverage. repco doesn't watch HN today. If your buyers post there, F5Bot catches it.

3. You write every DM yourself. Some operators want manual control over every outreach.

When repco wins

1. Keyword volume is too high to read every email. F5Bot's firehose breaks down at ~50+ matches/day. False positives flood the inbox. repco's classifier filters to high-intent only.

2. You want LinkedIn coverage. F5Bot is Reddit + HN only. repco watches Reddit + LinkedIn together.

3. You want speed. Per HubSpot's 2025 outbound benchmarks, DMs sent within 2 hours of a buying signal book 3-4x more meetings than DMs sent next-day. repco sends in real time; F5Bot requires you to be at your inbox.

4. You want a follow-up engine. F5Bot is alerts-only.

Frequently asked questions

Will repco add Hacker News monitoring?

Not on the public roadmap today. Reddit + LinkedIn are the current platforms. For HN coverage, F5Bot is the simplest option.

Is F5Bot reliable?

F5Bot is a hobbyist-run service with high uptime over many years, but it's free with no SLA. For mission-critical monitoring, repco's commercial infrastructure is more reliable.

Can I use both?

Yes. Some founders use F5Bot for HN keyword alerts and repco for Reddit + LinkedIn intent + outreach.

What's the upgrade path from F5Bot to repco?

Most operators upgrade when one of three things happens: keyword volume exceeds inbox triage capacity, they want LinkedIn coverage, or they want auto-drafted/auto-sent DMs.
