Side-by-side comparisons with verified, dated pricing and an API-openness score for every tool — built around real data, not recycled feature tables.
We compared A/B testing and experimentation tools on what developers actually need: server-side testing, feature flags, open APIs, CLI and MCP access, and transparent pricing. Every price is verified and dated, with an API-openness score for each tool.
We compared 11 heatmap tools on verified pricing (dated), free tiers, session replay, A/B testing, and two axes most guides ignore: how openly you can export your data, and whether an AI agent can reach it. Includes an API-openness score for every tool.
Looking to replace Crazy Egg? We compare 6 alternatives on verified, dated pricing, free tiers, session replay, A/B testing, and data portability — including a genuinely free option and tools with server-side testing Crazy Egg lacks.
Microsoft Clarity is free and capable, but it has real limits: no native A/B testing, no surveys, aggregate-only data, and 30-day retention. We compare 6 alternatives on verified pricing, testing, and data portability — for when free isn't enough.
Looking for a Hotjar alternative? We compare 7 tools on verified, dated pricing, session replay, A/B testing, and data portability — including the free options and the developer-friendly ones. Note: Hotjar is now part of Contentsquare, which changes the calculus.
Optimizely doesn't publish its pricing, and for many teams it's more platform — and more cost — than they need. We compare 7 alternatives on verified pricing, server-side testing, feature flags, and data portability, including open-source and flat-priced options.
VWO doesn't publish its pricing, and after the AB Tasty merger its plans are in flux. We compare 7 alternatives on verified pricing, server-side testing, feature flags, and data portability — including open-source and flat-priced options you can actually budget for.
Hotjar vs Microsoft Clarity, compared on verified pricing, session replay, surveys, data portability, and what each one can't do. Clarity is free; Hotjar is paid with surveys — but neither runs A/B tests. Here's how to choose, plus a third option.
VWO vs Optimizely, compared on server-side testing, feature flags, data portability, and pricing. Both are powerful — and both are quote-only, so neither publishes a price. Here's how to choose, plus transparent-pricing alternatives.
