Notes from the Autonnel project
Opinions, decisions, and the occasional rant. No marketing copy.
A/B testing whole funnels, not buttons
A per-page test measures a conditional probability that your own change moves. Here is the arithmetic for testing a funnel end to end instead.
Server-side conversion tracking for Meta and TikTok, end to end
Tracing a click id from the ad click through the order form to the server-side postback, using the code path Autonnel actually runs. No marketing copy.
A CartFlows alternative that does not need WordPress
CartFlows is good if you already run WordPress. If you do not, the real cost is not the licence, it is the CMS and the compatibility surface you inherit.
Prisma on workerd: everything that broke and how we fixed it
Four failures from running Prisma 7 and Astro on Cloudflare Workers: hanging connections, and a compatibility date that corrupts every SSR page.
Self-hosting a checkout: what you are actually signing up to run
The operational bill for self-hosting a checkout: Postgres backups, two secrets you must never rotate carelessly, and where card data does not go.
The order state machine, and who owns each transition
Six states, all one-way. Autonnel's responsibility ends at PAID and the commerce backend owns everything after. Here is why, and what that costs you.
What a funnel actually costs on Cloudflare Workers at 100k sessions
Worked from Cloudflare published rates on 2026-08-03: a 100k-session month costs $5 on Workers, and the meter that bites is not the request count.
Why pages are component trees, not HTML blobs
If an LLM returns HTML you cannot review it and cannot constrain it. Validated component trees are what make AI editing survivable in a checkout.
We deleted the 1% of GMV
Autonnel Cloud used to be $29/mo plus 1% of GMV. We removed the 1%. Here is the argument that killed it, and what the flat fee costs us.
One-click upsells on Shopify without a fee that scales with you
Zipify and ReConvert both price on how well your upsells do, and neither publishes the rate. What that costs as you grow, our own catch included.
Funnels for agents: giving an LLM write access to your money path
Most AI in funnel software writes copy into a box. We exposed orders, pages and refunds as MCP tools, and the hard part was the permission model.
Open-source ClickFunnels alternatives in 2026, compared honestly
Seven open-source funnel builders, checked against their actual licence files on 2026-08-03. Including ours, including where ours is the wrong choice.
Why I built another funnel builder when ClickFunnels, Funnelish, and CartFlows already exist
An honest look at ClickFunnels, Funnelish and CartFlows, and why the category deserved an open-source, AI-native rebuild in 2026.
AI-native, defined honestly - what it should mean and how Autonnel implements it
Most AI-native claims describe a chatbot in the corner. Here's a sharper definition and how Autonnel's four AI surfaces actually work.
Why Picocart, when Medusa already exists
Medusa is great. Picocart is not trying to compete with it - but Autonnel needs a different shape of commerce backend.
