No description of Backbone.js yet.
Most real estate deals aren't lost to better agents—they're lost to silence. When a part-time or newer agent juggles a day job, family, and clients, follow-up falls through the cracks. That lead who seemed interested? Gone to the agent who actually kept in touch. I built AgentSequence because I...

As answered by people managing Backbone.js and AgentSequence.
AgentSequence's answer:
It's free for up to 50 contacts and built specifically for real estate agents. Most CRMs charge $100+/month and overwhelm you with features. AgentSequence does one thing well: automated follow-up that pauses when someone replies. Simple setup, no credit card required.
AgentSequence's answer:
Price and simplicity. Competitors like Follow Up Boss or LionDesk cost $50-150/month and take hours to set up. AgentSequence is free to start, takes minutes to configure, and focuses only on the follow-up problem that actually costs agents deals. No feature bloat, no enterprise complexity.
AgentSequence's answer:
Next.js, React, Vercel, Resend, and Postmark.
AgentSequence's answer:
Part-time and newer real estate agents who know follow-up matters but struggle to stay consistent. People balancing a day job or family who can't justify expensive software but still want to stay in touch with their leads professionally.
AgentSequence's answer:
My family has been in real estate for over 25 years. I watched agents lose deals not because they weren't good, but because they got busy and stopped following up. The tools that exist are too expensive and complicated for someone just getting started. I built AgentSequence to solve that specific problem.

Nobody we talk to is upset with Backbone. It did exactly what it promised. Teams leave because of everything that grew up around it. RequireJS, Handlebars 1.x and old jQuery plugins have gone quiet, and in our example, jQuery Mobile was... - Source: dev.to / 18 days ago
