Common Room vs Warmly: pricing, features, and verdict for 2026

Common Room vs Warmly: Side-by-Side

Common Room aggregates community and product signals to surface engaged accounts. Warmly de-anonymizes site visitors in real time and routes them to reps. For most B2B teams without an existing developer community, Warmly delivers faster, measurable pipeline per dollar spent.

What Common Room Actually Does

Common Room aggregates signals from 30+ sources, including GitHub stars, Slack activity, Discord messages, LinkedIn comments, and in-app telemetry, to surface accounts already engaged with your brand. It doesn't create intent signals. It reads ones you've already earned through community investment.

The platform connects dots across touchpoints and alerts your rep, per Common Room's product documentation. But the requirement is existing community scale. If your GitHub repo has 200 stars and your Slack has 50 members, you're paying $20,000+ per year to watch a quiet room. Its AI layer, Room Intelligence, only matters if you have signal volume to work with, per Common Room's 2025 product updates.

What Warmly Actually Does

Warmly de-anonymizes website visitors and routes signals to your reps via Slack alerts, CRM tasks, or its built-in AI SDR that sends outreach when a target account visits your site. It identifies the company behind anonymous traffic through IP resolution, then layers on contact data via Apollo, ZoomInfo, and Bombora integrations, per Warmly's 2025 documentation.

The free plan covers up to 500 monthly visitors at company level. Paid plans start at $700/month and unlock contact-level identification and AI SDR sequences. Warmly's AI SDR detects when a named prospect hits your pricing page and sends personalized outreach automatically, without a human in the loop. The limitation: Warmly only sees people who come to your site.

Pricing: What You Actually Pay

Common Room is expensive and opaque. Warmly is accessible but scales up fast. The real question isn't the subscription fee. It's how fast each tool produces pipeline relative to what you pay.

Common Room doesn't publish list pricing. Teams typically pay $20,000 to $50,000 per year depending on data volume and seat count, per G2 reviews for Common Room (2025). Warmly's Startup tier begins at $700/month, rising to $1,600/month for AI SDR features and higher visitor volume, per Warmly's public pricing page (2025). For a 10-person SaaS team with 500 weekly visitors, Warmly at $8,400/year costs 2.4 times less than the minimum Common Room contract, for a tool that matches your actual infrastructure.

Who Should Use Which Tool

Choose Warmly if you have existing site traffic and want to convert more of it into pipeline without hiring SDRs. Choose Common Room if your GTM motion runs through a developer community or open-source project and you need to operationalize those signals.

• Warmly fits: teams with 1,000+ monthly visitors not capturing most of them; companies that want AI-triggered outreach without a full SDR team; startups under 20 people who can't justify $20,000+/year
• Common Room fits: developer-tools companies with active GitHub, Discord, or Slack communities; PLG companies with self-serve usage generating behavioral telemetry; orgs with DevRel teams producing consistent signal volume

If you're a traditional B2B SaaS company without a community motion, Common Room won't give you much.
