Harp vs Waalaxy
Waalaxy is a popular, affordable tool for LinkedIn prospecting and cold email, with plans by monthly invitation volume, a unified LinkedIn inbox and a Chrome extension. Harp is built for a different buyer: someone whose AI agent runs outbound and who wants LinkedIn driven from their own browser like a person.
The short answer
If you want simple, low-cost LinkedIn prospecting you can start today, Waalaxy is built for that. If your AI agent should research, sequence and answer replies across email and LinkedIn, Harp is built for that.
