DialerJazz vs Pharo

DialerJazz is an open-source power dialer for outbound sales calls, with web, self-hosted, and API access. It offers swipe-based dialing, automated sequential dialing, and manual calling. Its lead tools track leads, companies, and contacts, accept CSV imports, and support a disposition workflow. Users can create campaigns, assign leads, track progress, and filter by status; the dashboard shows real-time statistics, a campaign overview table, and quick actions. Calling uses WebRTC and can connect to Telnyx, Twilio, or a custom WebRTC provider. The documented setup requires an InsForge project for Postgres, authentication, and storage, plus a Telnyx account for WebRTC calls. DialerJazz is Docker-ready and documents deployment to Docker or any cloud provider. Its REST API covers campaigns, leads, call logs, settings, and Telnyx tokens, with offset pagination for list endpoints. The project is MIT-licensed and lists rate limiting, Zod validation, and centralized error handling. The free plan costs nothing. Setup requires Node.js 22+, and only the latest main branch receives security updates.

Pharo is a web-based outbound sales platform that builds campaigns, verifies contact numbers, places parallel calls and records outcomes. Entering a domain can produce a dial-ready campaign in under five minutes. Campaigns can use buying signals for funding, hiring and technology changes, with source information attached. Pharo pre-screens direct numbers against live network signals and blocks company or national Do Not Call registrations. Its WebRTC bridge is described as connecting in under 200 milliseconds when a person answers. Call support includes live scripts, objection battlecards, recordings, playback and AI summaries. Salesforce and HubSpot have live, bidirectional connectors; Claude and ChatGPT connect through an MCP server. Pipedrive, Outreach, Salesloft and Apollo are marked in build. Starter costs $99 a month ($99/user/mo), with two dialer lines, 5,000 monthly credits and one caller ID. Pro costs $179 a month, with four lines, 20,000 credits and five caller IDs. Dialing attempts are unlimited; top-ups cost $10 per 1,000 credits. Starter and Pro include seven-day trials with 1,000 credits and no credit card.
