OpenFunnels

Overview

OpenFunnels is an open-source funnel builder for teams that want to keep customer data on infrastructure they control. It suits operators with the technical capacity to run a web application and build follow-up workflows around captured leads. Its appeal is a broad funnel toolkit without a software charge; its trade-off is that production hosting and security are yours to configure.

Key features

Build and publish

The visual editor combines drag-and-drop sections, columns, and blocks with undo, redo, autosave, and responsive previews. Fifteen categorized starter layouts offer a starting point, while versioned template packs can be imported or exported for reuse. Draft previews, slug-based URLs, and verified custom domains support a path from editing to publication.

Funnels can be exported to HTML, Laravel, React, Vue, WordPress, Shopify, and WooCommerce. That gives teams options for carrying funnel work into different web and commerce environments, but it does not make OpenFunnels a hosted publishing service.

Capture and organize leads

Forms accept configurable and conditional fields, preserve submissions, and collect UTM and referrer attribution. Contact records can hold statuses and notes, and filtered segments can be exported to CSV. The opportunities CRM adds configurable sales pipelines, deal-value forecasts, and won or lost outcomes; funnels can optionally create opportunities. This is useful when funnel activity should feed a sales process, though it is more than a team needs if the only goal is a standalone landing page.

Automate and measure

Automation Studio connects triggers and actions with waits, yes/no branches, CRM updates, email, and signed webhooks. Run timelines, retries, and starter recipes help operators manage workflows beyond a single form notification. Webhook destinations on private networks are blocked by default, while allowed external targets receive signed JSON events.

Analytics track privacy-conscious events, conversion trends, traffic sources, and drop-off. Experiments use stable A/B variant assignments, giving teams a way to compare funnel variants. Email delivery, external webhooks, and optional draft generation through a provider-neutral Responses-compatible backend driver round out the integrations.

Pricing

The OpenFunnels plan costs free and is open-source, self-hosted software under the MIT License. There is no paid tier described, so the meaningful cost is operating the deployment rather than a subscription. This suits teams prepared to provide infrastructure; it is a weaker fit for buyers who want a managed service with hosting handled for them.

Production requires PHP 8.3 or newer, a web server, a queue worker, a minute-level scheduler, and SMTP or another Laravel mail transport. PostgreSQL or MySQL is recommended for normal production installations. The Docker Compose evaluation stack is for local evaluation and does not configure TLS, a reverse proxy, or custom-domain infrastructure; production operators must configure HTTPS, backups, and services themselves.

Platforms

OpenFunnels is available as self-hosted web software. Its custom-domain publishing and export options provide flexibility, but running the application securely remains an operational responsibility.

Who it's for

OpenFunnels is a strong fit for technically capable operators who want funnel editing, lead capture, CRM, automation, and analytics while keeping customer data under their control. It is less suitable for businesses seeking a turnkey funnel service or a checkout-centered product: built-in checkout, upsells, and order bumps are absent.

Pros and cons

• Pros: The editor, CRM, automation, analytics, and A/B experiments cover much of the funnel-to-follow-up workflow in one self-hosted product.
• Pros: The MIT license and free plan avoid a software subscription, while customer data remains on infrastructure the operator controls.
• Pros: HTML, framework, CMS, and commerce exports give teams several ways to reuse funnel work elsewhere.
• Cons: Production deployment requires a PHP application stack plus mail, queue, scheduler, HTTPS, and backup configuration.
• Cons: The local evaluation setup does not prepare TLS, reverse proxy, or custom-domain infrastructure, so it is not a production shortcut.
• Cons: No built-in checkout, upsells, or order bumps means commerce-focused operators need another solution for those functions.

Alternatives

Consider Autonnel if its free self-hosted plan, which supports Node or Cloudflare Workers and requires a bring-your-own LLM key, better matches your deployment approach.

ConvertFlow may suit teams seeking a web-based option with a free tier capped at five funnel campaigns; integrations require a paid plan.

Influx OS is another web-based option with a free starting plan and a paid Launch plan at $79 a month.

Choose Systeme.io if a free web plan with published caps of 2,000 contacts, three sales funnels, one course, one blog, and one custom domain fits better.

Fynlix is worth considering when checkout and upsells matter: its free Basic plan includes those features, alongside 30 AI credits monthly, three funnels, and one seat.

Launchtic is a self-hosted alternative whose free plan includes one workspace and one admin, with unlimited funnels, contacts, workflows, broadcasts, and domains.

Consider CartFlows for a self-hosted alternative with a paid Starter plan at $99 a year for one website and a funnel builder.

CheckoutChamp is a paid alternative with an Enterprise plan priced at $300 a month.

Verdict

Choose OpenFunnels if you want a free, MIT-licensed funnel toolkit and can operate its production stack yourself; the combination of lead management, automation, and analytics is its strongest case. Look elsewhere if you need managed hosting or built-in checkout and upsells, since those gaps would leave important operational or commerce work outside the product.
