There's no meaningfully-functional "forever free" challenge platform — platforms that promise it usually cap participants so aggressively or add so much friction that they're not usable for real marketing challenges. What does exist is a healthy set of free trials and low-cost entry tiers that let you launch a real challenge without spending much upfront.
This guide ranks the best free-trial and low-cost entry options honestly.
How we chose
Three criteria:
- Generosity of the free trial. Credit card required? How long is the trial? What features are gated?
- Entry-tier affordability. If you continue past the trial, what's the lowest realistic monthly cost to run a real challenge?
- Time-to-launch. Can you actually build and publish a challenge during the trial window?
1. Chalzy (our top pick)
Free trial: 14 days, full platform access, no credit card required.
Entry pricing after trial: Starter $39/mo.
Why it ranks first:
- No credit card to start. You don't risk forgetting to cancel and getting charged — the trial simply ends if you don't upgrade.
- Full platform access during the trial. AI content generation, AI image generation, paid challenges, white-label branding, leaderboards, teams, live video — all available.
- Fast time-to-launch. The AI Challenge Wizard generates a full challenge (title, daily content, assignments, images, emails) from a single description, so you can have a real challenge live inside the trial window and start getting real signups.
- Real free trial, not a "limited mode." You're not stuck with a crippled version during the trial — you get the whole thing.
Trade-offs: No ongoing free tier after the 14 days. If you want to keep running challenges, you'll need to pick a paid plan (entry tier $39/mo).
2. Heights Platform
Free trial: Available; check current terms at heightsplatform.com.
Entry pricing: Basic $39/mo.
Strengths:
- Low entry price matching the challenge-platform category.
- AI content generation included at the basic tier.
- Built-in community features.
Trade-offs:
- AI and community features are tuned for courses, not time-bound challenges.
- Limited challenge-specific templates.
- Challenges require adapting course-oriented tools rather than using a purpose-built flow.

3. My Challenge Creator
Free trial: Not the main model; entry pricing is the primary low-cost option.
Entry pricing: Basic $29/mo.
Strengths:
- Cheapest entry in this list.
- Simple, no-frills setup good for solo creators who want to run one occasional challenge.
- Covers the basics of participant signup and email.
Trade-offs:
- No AI content generation.
- No team features or advanced engagement mechanics.
- Very limited branding options.
- Can feel dated next to modern alternatives.

4. Teachable
Free tier: Available with transaction fees and significant feature limitations.
Entry paid pricing: Basic $59/mo (reduces transaction fees).
Strengths:
- One of the few platforms with an ongoing free tier, useful if you want to experiment without any financial commitment.
- Strong for course-style content.
- Transaction processing built in.
Trade-offs:
- Free tier has meaningful transaction fees that eat into paid-challenge revenue.
- No native challenge features — running a challenge means working around the course model with drip content and manual emails.
- Limited branding on free tier; upgrade required for customization.

5. Kajabi
Free trial: 14 days.
Entry paid pricing: Basic $149/mo.
Strengths:
- 14-day trial to explore the all-in-one platform.
- If you want one platform for courses, memberships, emails, and challenges combined, the trial lets you assess the whole ecosystem.
Trade-offs:
- Credit card typically required to start the trial.
- Post-trial pricing is the highest in this list — $149/mo entry and $199–$399/mo on higher tiers.
- Challenges are treated as courses, so you won't get native challenge mechanics even with full access.

How to make the most of a free trial
Four tests to run during any free trial:
- Time from signup to published challenge. The faster, the better. If you're still in setup by day 7 of a 14-day trial, something is wrong with the tool or its guidance.
- AI quality test. If the platform has AI content generation, generate a real challenge in your niche and check whether the output is usable or needs heavy rewriting.
- Participant view. Create a test account and walk through the challenge as a participant. Is the daily experience clean, branded, and motivating?
- Branding audit. Does the challenge look like yours, or like a third-party SaaS tool bolted on? Branding friction kills trust for paid challenges especially.
What to avoid
- Trials that require a credit card and aggressively bill on day 15 — easy to forget.
- Free tiers with high transaction fees — what looks cheap can be expensive once you start selling paid challenges.
- Tools that only let you run "demo" challenges during the trial, not real ones — you can't evaluate what you haven't actually used.
How to choose
Most creators are best served by picking one platform with a generous, no-credit-card trial, launching a real challenge during that trial, and committing if the challenge actually produces signups and engagement. Chalzy is built for exactly this — the AI gets you to launch in an afternoon, and a real 7-day challenge can run and convert inside the 14-day window.
