TL;DR
Refiner is a mature in-product survey platform for SaaS teams - NPS, CSAT, PMF, user targeting, and deep integrations with HubSpot, Salesforce, and Segment. It starts at $99/month with no free plan. Mapster covers the same core use cases - in-product surveys, user segmentation, NPS/CSAT/CES/PMF scoring - at $19/month, with a free plan that includes the widget and templates. Choose Refiner if you need enterprise-grade audience targeting and CRM integrations. Choose Mapster if you want the same core functionality without the $99/month price tag.

Where the real differences are
Both tools solve the same problem. The differences come down to price, setup complexity, and how far you need to scale.
1. Both tools are built for SaaS in-product surveys
Unlike Typeform or SurveyMonkey, both Refiner and Mapster are purpose-built for SaaS product teams. Both install via a JavaScript widget, both link responses to real users, and both calculate NPS, CSAT, CES, and PMF scores automatically. If you are coming from a generic survey tool, either will be a major upgrade.
The question is not whether you need a purpose-built in-product survey tool - you do. The question is whether you need Refiner's enterprise feature set at $99/month or Mapster's focused, affordable version at $19/month.
2. Pricing: $99/mo vs $19/mo - and Refiner has no free plan
Refiner's Starter plan starts at $99/month. There is no free plan - only a 14-day trial. Their Growth and Business plans run higher, with pricing that scales based on monthly tracked users. For early-stage startups or small teams, this price point makes Refiner hard to justify.
Mapster Pro is $19/month (or $97/year - effectively $8/month). Mapster's free plan is permanent with no time limit and includes the core widget, NPS/CSAT/PMF templates, and user segmentation. You can run real surveys on real users before spending a dollar.
3. Refiner has more advanced audience targeting - if you need it
Refiner's standout feature is its audience targeting engine. You can target surveys based on user attributes, events, session counts, feature usage, and behavioral rules. If you want to survey users who completed onboarding, used Feature X at least 3 times in the last 7 days, and are on the Pro plan - Refiner can do that precisely.
Mapster targets surveys based on user attributes you pass through the widget - plan, role, region, and any custom fields. For most teams running NPS quarterly, CSAT after support interactions, and PMF once a month, this is sufficient. If your survey strategy requires complex behavioral triggers, Refiner's targeting logic is more powerful.
4. Refiner has deeper CRM integrations
Refiner integrates natively with HubSpot, Salesforce, Intercom, Segment, Slack, and others. If you need NPS scores to flow directly into Salesforce contacts or trigger HubSpot workflows based on survey responses, Refiner has this built in.
Mapster integrates via Slack and Zapier, which covers most use cases - pushing responses to Slack, Google Sheets, or a CRM via Zapier. If you need a direct native HubSpot or Salesforce sync without Zapier, Refiner is the stronger choice.
5. Mapster is faster to set up and easier to use
Refiner's power comes with configuration overhead. Setting up audience segments, trigger rules, and integration flows takes time. For teams without a dedicated growth engineer, Refiner can feel complex to get right.
Mapster is designed to get your first survey live in under 10 minutes. Add the widget script, pick a template, and surveys start running. Most teams send their first NPS survey the same day they sign up. If speed to first response matters more than targeting precision, Mapster wins on simplicity.
6. Where Refiner is the better choice
Refiner is the right tool if you are running a mature SaaS product with a large user base, need precise behavioral targeting for survey delivery, and want NPS scores synced directly into Salesforce or HubSpot contacts. At that scale, the $99/month price is a rounding error and the advanced features earn their keep.
If you are pre-series B, running a lean team, and just need reliable NPS, CSAT, PMF, and exit surveys with segmentation - Mapster delivers the same core output at a fraction of the cost.
