App-like frontend
The interface uses standard Django templates, HTML, CSS, Bootstrap, and vanilla JavaScript while behaving like a compact productivity app.
Product direction
Sonar is a lightweight cold outreach platform focused on simplicity, speed, deliverability, and a clean app-like user experience.
Light backend
The core app still avoids heavy realtime infrastructure. Scheduled campaigns, safe import checks, and analytics snapshots use lightweight management-command workers where the product now needs background execution.
Email first
Users connect SMTP and IMAP mailboxes, send outreach, schedule campaigns, manually fetch replies, track opens, and manage campaign lead state inside the campaign workspace.
Clean data boundaries
Contacts are neutral reusable records. Campaign leads hold campaign-specific reply status, lead status, notes, and outreach history.
Workspace layer
Accounts start in a default workspace. Paid plans can unlock additional workspaces and team seats so multiple users can collaborate without turning Sonar into enterprise software.
What Sonar is not
- Not an enterprise CRM.
- Not a workflow automation platform.
- Not a heavily asynchronous sales automation suite.
- Not a heavy multi-team enterprise suite; workspace support is intentionally lightweight and plan-gated.
