DialerJazz

Overview

DialerJazz is an open-source power dialer built around outbound sales calling and lead workflows. It is best suited to teams willing to run and configure their own web application.

Key features

Three dialing modes let agents choose how much control to retain: swipe through leads one at a time, move automatically through a list with sequential power dialing, or place calls manually. That flexibility suits different outbound routines, while teams looking for a managed calling product may prefer a service that handles setup for them.

Lead and company/contact records, CSV import, and call dispositions support basic follow-up in the same workflow as dialing. Campaigns let users assign leads, track progress, and filter by status; the dashboard adds real-time statistics, a campaign overview, and quick actions. This covers the core organization of outbound work, but the described CRM scope is focused on leads and campaigns.

DialerJazz supports WebRTC calling through Telnyx and can connect to Telnyx, Twilio, or a custom WebRTC provider. The documented quick start nevertheless requires Telnyx for WebRTC calls. Authentication includes email and password, Google OAuth, email verification by OTP, and password recovery. Its REST API covers campaigns, leads, call logs, settings, and Telnyx tokens, with offset pagination for list endpoints.

The project is Docker-ready and documents deployment to Docker and cloud providers. Its README lists rate limiting, Zod validation, and centralized error handling, but does not state a compliance certification. Only the latest main branch receives security updates; vulnerabilities should be sent privately to the maintainer, who aims to respond within 48 hours. Teams that need longer support coverage or a formal compliance assurance should account for that distinction.

Pricing

Open-source: free. The MIT-licensed software has no license charge, making it a fit for teams able to provide their own deployment and service accounts. The free price does not remove the operational requirements: self-hosting requires Node.js 22+, an InsForge project, and a Telnyx account for WebRTC calls. InsForge supplies Postgres, authentication, and storage; Telnyx supplies calling. No seat or usage quota is stated for the plan.

Platforms

DialerJazz is categorized for API, self-hosted, and web use. Docker and cloud deployment options support teams choosing their own hosting environment, while the Node.js 22+ requirement sets a technical baseline for setup.

Who it's for

DialerJazz is a sensible fit for outbound sales teams that want swipe, sequential, and manual dialing alongside campaign and lead management, and have the capacity to configure the supporting services. It is less suitable for buyers who want a turnkey dialer, do not want to manage hosting, or need a stated security certification and broader branch support.

Pros and cons

Pros

• Three dialing modes: teams can alternate between agent-led selection, automated sequential calls, and manual dialing.
• Lead and campaign workflow: CSV import, dispositions, assignments, status filters, and campaign progress tracking keep core outbound tasks together.
• Open-source and deployable: the MIT license, Docker readiness, and documented cloud deployment give technically capable teams control over hosting.
• Documented API: endpoints for campaigns, leads, call logs, settings, and Telnyx tokens can support integration work.

Cons

• External setup is essential: self-hosting calls for Node.js 22+, InsForge, and Telnyx, so the zero-price plan still carries setup and service dependencies.
• Security support is narrow: updates apply only to the latest main branch, and the project states no compliance certification.
• Calling-provider choice has a practical caveat: although Telnyx, Twilio, or custom WebRTC providers are described, the documented setup requires Telnyx for WebRTC calls.

Alternatives

Sales Dialer Software is the category guide for comparing sales dialers. Consider Callmaker if a paid product with a free pilot, full functionality during a long trial, and Mac, Windows, and web platforms is a better fit. ConnectAndSell offers a one-day Test Drive Experience without CRM integration, and may suit a short evaluation; its free plan is available.

JustCall Sales Dialer is a paid option with a free trial, broad platform support from mobile and desktop to browser extension, and a Team plan at $29 a month billed annually. Callingly is another paid, trial-available choice; its Starter plan costs $100 a month and includes $100 of monthly usage, with additional AI-call, talk-minute, and SMS-segment rates. Choose CallTools for a power contact center whose plan can be billed month-to-month or annually, rather than DialerJazz's self-hosted setup.

Mojo Dialer is a paid alternative with web, Android, and iOS support, including a Mojo Caller ID plan at $10 a month. Channels has a free plan and trial, plus a Plus plan at $24 a month billed annually that includes 5,000 web calls and three users. DialerBee is a paid, trial-available option with Android, iOS, web, and API support; its Starter plan is $69 a month and supports up to 20 agents.

Verdict

Choose DialerJazz if your outbound team wants multiple dialing styles and basic campaign and lead management without a software license fee, and can handle self-hosting and external service setup. Look elsewhere if you want a managed dialer or need security support beyond the latest main branch; those tradeoffs matter more than the zero-price license.
