A/B testing pricing comparison
Every a/b testing tool we track, side by side on price. Numbers pulled from each vendor's published pricing page and refreshed weekly. No invented benchmarks, no estimated tiers.
Free tiers
What each tool gives you on the free plan, before any paid upgrade. Tools without a free plan are listed in the next table.
| Tool | Plan | Contact limit | Monthly send limit | Source |
|---|---|---|---|---|
| PostHog | Free + Pay-as-you-go | · | · | Vendor |
Entry paid plans
The cheapest published paid plan for each tool. This is the upgrade target after a free trial or free tier. Custom / contact-sales plans are excluded; see the per-tool page for those.
| Tool | Plan | Monthly price | Contact limit | Send limit | Action |
|---|---|---|---|---|---|
| PostHog | Boost | $250 /mo | · | · | View PostHog |
| Unbounce | Starter | $22 /mo | · | · | View Unbounce |
| Convert | Growth | $299 /mo | · | · | View Convert |
Mid-tier paid plans
The plan above entry-tier where most growth-stage publishers land as the contact list scales. Tools without a published mid tier jump straight to enterprise / contact-sales pricing and are omitted here.
| Tool | Plan | Monthly price | Contact limit | Send limit |
|---|---|---|---|---|
| PostHog | Scale | $750 /mo | · | · |
| Unbounce | Build | $74 /mo | · | · |
| Convert | Pro | $420 /mo | · | · |
Beyond price
Cost is one dimension. The pages below cover the same a/b testing set on different axes.

How this table is built
- Every price and limit is captured from the vendor's own published pricing page. We do not estimate, interpolate, or carry over numbers from third-party reviews.
- Pricing is refreshed weekly via a cron-driven Playwright scrape with editorial preservation: low-confidence scraped values never overwrite verified prior values.
- Ranking inside each table is free-plan-first, then ascending entry price, then alphabetical. Affiliate relationships do not influence ranking.
- "Custom" or "contact sales" plans are omitted from the price columns. The per-tool page (/tools/{slug}) shows the full plan ladder including enterprise tiers.
- Tools without a published mid tier (free + entry + enterprise only) are omitted from the mid-tier table rather than padded with placeholders.
