Autonnel

Autonnel is an open-source funnel builder for e-commerce, with prompt-generated landing, checkout and upsell pages. It best suits teams that want to shape and operate their own funnel stack, while its managed option gives teams a hosted route. Its appeal is the combination of structured page editing, commerce tools and deployment choice; the trade-off is that self-hosting also means managing infrastructure and an LLM key.

Overview

Autonnel brings funnel creation, checkout and performance analysis into one product. Its canvas builder works with real components, and records edits as diffable JSON—a useful distinction for teams that want changes represented in a form they can inspect rather than only through a visual editor.

The project uses the Apache-2.0 license, which permits commercial, modified and private use. That makes it a plausible foundation for teams adapting the software, but does not remove the operational work of deploying and securing it.

Key features

• Prompt-generated pages: Generate landing, checkout and upsell pages from prompts, then edit their components on a canvas. This suits teams looking to accelerate page creation without giving up a visual editing surface.
• Commerce and payments: Adapters include Shopify, WooCommerce and the open-source Picocart; payment documentation lists Stripe and PayPal. Conversion postbacks cover Facebook, TikTok, Bing and Google, making the product relevant to shops that need funnel activity connected with ad platforms.
• Post-purchase offers: One-click upsells charge the saved card without sending the buyer through another checkout. That can reduce friction in an offer flow, though it depends on having a saved payment method.
• Funnel analytics: Step-by-step conversion and drop-off reporting uses 17 built-in payment and form events queried with DuckDB. This provides more than a page builder alone, with event-based funnel analysis built in.
• Scheduled analysis: An agent sends funnel data through an LLM and can notify a team when performance changes. Teams should account for the required LLM key when choosing self-hosting.
• Developer access: An MCP server, Claude skills and an API with scoped Bearer keys provide integration and automation paths for technical teams.
• Checkout and testing: Built-in checkout, upsells and order bumps, email automation, A/B testing and custom domains cover core funnel needs. A custom domain starts with the paid plan.

Pricing

Self-hosted is free, billed $0 forever. It includes self-hosting on Node or Cloudflare Workers and all adapters, but requires your own LLM key and infrastructure. It fits technically capable users who value control and are prepared to deploy and maintain the service. The setup is not turnkey: the self-hosting documentation requires session and credential-encryption secrets outside development, and there is no open registration.

Managed costs $29 a month, billed $29 / mo flat, with 0% of revenue. Building and testing are free; a custom domain starts the paid plan. Marketplace templates and plugins are included, as are email and Slack support. This is the clearest fit for teams that want hosting and support without a revenue share, but need a custom domain or the included marketplace resources.

Enterprise has custom pricing. It adds dedicated resources, SSO/SAML, an on-prem option and a priority SLA, making it the relevant tier for organizations with deployment or service-level requirements beyond the managed plan.

Platforms

Autonnel is available through the web and API, and supports Linux and self-hosted deployment. Self-hosting options include Docker or Node.js, as well as Cloudflare Workers. That range gives infrastructure-owning teams deployment flexibility, while the managed plan avoids running the application themselves.

Who it's for

Autonnel is strongest for e-commerce teams that want prompt-assisted funnel building alongside checkout, post-purchase offers and conversion analysis. Its self-hosted plan is explicitly suited to hackers, open-source maintainers and teams running their own infrastructure. Less technical operators who want a custom domain can choose Managed, but should weigh the monthly fee against the additional control of running it themselves.

Pros and cons

• Pro: Apache-2.0 licensing and self-hosting support give technical teams room to run and adapt the software for commercial use.
• Pro: Page generation, checkout, one-click upsells, email automation and funnel analytics sit in the same product.
• Pro: Managed pricing is a flat $29 a month with 0% of revenue, rather than a revenue-based fee.
• Con: The free self-hosted route requires an LLM key, infrastructure and security configuration, so its zero price does not mean zero operational effort.
• Con: Custom domains require the paid plan, which limits the usefulness of free building and testing for a live branded storefront.
• Con: Enterprise capabilities come with custom pricing, so organizations cannot compare that tier against a published fixed price.

Alternatives

Fynlix may suit a buyer wanting a free forever tier with 30 AI credits monthly, three funnels, one seat, checkout, upsells and analytics.

Influx OS offers a free platform-exploration tier and a paid Launch plan, so it may suit readers comparing a free starting point before selecting paid service. Launchtic is another self-hosted option, with a free tier allowing one workspace and one admin alongside unlimited funnels, contacts, workflows, broadcasts and domains.

OpenFunnels is an alternative open-source, self-hosted funnel product. Systeme.io may be preferable to readers who want its free plan's 2,000 contacts, three sales funnels, one course, one blog and one custom domain.

CartFlows is an option for readers seeking a self-hosted funnel builder for a website, while FunnelKit is another self-hosted alternative with checkout-focused plans.

Verdict

Choose Autonnel if you want an open-source e-commerce funnel builder that combines prompt-generated pages, checkout, post-purchase offers and event-based analytics, with the option to self-host or pay for managed service. Its strongest case is for technical teams that value control without sacrificing commerce functionality. Look elsewhere if you need a fully hands-off free service: the self-hosted option requires your own infrastructure and LLM key, and branded custom domains start with the paid plan.
