If you're comparing tools for creators, Systeme.io and Kit (formerly ConvertKit) both offer a free way in — but they're built for very different businesses. Here's the honest breakdown.

Systeme.io

Funnels, a course, and a real affiliate program — free from day one. Kit's free plan is email-only, with no funnels or affiliate program for your own products.

Kit (ConvertKit)

A clean, specialized newsletter tool with strong automation and a subscriber-recommendation network — but no funnels, no structured course platform, and no affiliate program for your own products.

Pricing Comparison

• Entry price · Systeme.io: $0/month (free forever) · Kit (ConvertKit): $0/month (Free plan, up to 10,000 subscribers) — paid plans from $33/month (Creator)

• Free plan · Systeme.io: Yes — funnels, email, 1 course, affiliates included · Kit (ConvertKit): Yes — email marketing, unlimited landing pages/forms, digital product sales

• Sales funnels · Systeme.io: Yes, multi-step funnels on every plan including free · Kit (ConvertKit): No dedicated funnel builder — only single landing pages and forms

• Course hosting · Systeme.io: Yes, 1 course free / unlimited from $47/mo · Kit (ConvertKit): Digital product/download sales only — not a structured multi-lesson course platform

• Affiliate program management · Systeme.io: Yes, built in on every plan including free · Kit (ConvertKit): Not available for your own products — only Kit's own "Recommendations" network for cross-promoting other newsletters

The Real Cost Difference

Both platforms let you start at $0. But Kit's free plan is an email and newsletter tool: solid for list-building and simple digital downloads, with no multi-step funnel builder, no structured course platform, and no way to recruit affiliates to sell your product for a commission. Systeme.io's free plan gives you email marketing plus funnels, one course, and a built-in affiliate program — features you'd need separate tools (and separate subscriptions) to match on Kit.

Quick take: Kit is excellent for newsletters, but selling a course or running an affiliate program needs separate tools. Systeme.io's free plan already includes both.

Where Kit Wins

To be fair: Kit is purpose-built for newsletter-first creators, with a cleaner writing and sending experience, strong subscriber tagging and automation for email specifically, and its "Recommendations" network that can help you gain new subscribers from other creators' newsletters. If email is your entire business model, Kit's email tooling is more specialized than Systeme.io's.

Where Systeme.io Wins

For solopreneurs who want to sell a course, run funnels, and recruit affiliates — not just send newsletters — Systeme.io's free plan covers all of it in one login, without adding a separate course platform or affiliate tool on top of an email subscription.

Bottom Line

If your business is a newsletter and simple digital downloads, Kit's free plan is a strong, purpose-built option. If you want funnels, a course, and an affiliate program alongside your email marketing, Systeme.io's free plan covers more ground at $0.

Frequently Asked Questions

Can I sell a structured, multi-lesson course on Kit?

No — Kit supports simple digital downloads, not a structured course platform with lessons and modules.

Does Kit have an affiliate program for my own products?

No — Kit's "Recommendations" network is for cross-promoting other newsletters, not for recruiting affiliates to sell your product.

Is Systeme.io's free plan a good alternative for course creators?

Yes — it includes one free course, multi-step funnels, and a built-in affiliate program, all at $0/month.

You Won't Be the Only One

Systeme.io is rated 4.8 out of 5 from 2,100+ reviews on Capterra (checked September 2026), so you're not betting on an unknown tool. That matters when you're trusting a tool with your funnels and customer data.
