Mapster

Mapster is a web-based product feedback survey tool for SaaS founders and lean product teams. It is a strong fit when a small team wants segmented in-product feedback and standard product metrics, but less suitable for enterprise access-control needs or response volumes that exceed its plan caps.

Overview

Mapster supports surveys on websites and inside products, as well as distribution by link, embed, or widget. Its widget can connect answers to a user ID, plan, role, region, or custom attributes, letting product teams compare feedback across customer segments rather than read responses in isolation.

Templates score NPS, CSAT, CES, and product-market-fit surveys, including the Sean Ellis 40% PMF benchmark. Branching sends respondents to different questions according to their answers, which can make follow-ups more relevant. Zapier connects responses to Slack, Google Sheets, WhatsApp, email, Notion, Airtable, HubSpot, and more than 6,000 other apps. Mapster also sends new responses to Slack channels or direct messages in real time.

Key features

• User-linked segmentation: Attaching identity and account attributes to widget responses helps a team see how feedback differs by plan, role, or region. That is valuable for product decisions, though the stated attribute-linking applies to the widget.
• Scored templates and branching: Automatic scoring for four familiar feedback measures reduces manual interpretation, while branching can tailor question paths. Together, these suit teams that need structured product feedback rather than a simple one-size-fits-all questionnaire.
• Integrations and alerts: Zapier provides a broad route into other tools, and real-time Slack delivery can keep teams aware of incoming feedback. Teams dependent on another workflow can use Zapier rather than relying on Slack alone.
• Security and privacy: Traffic uses HTTPS with TLS 1.2 or higher, and stored database data uses AES-256 encryption. Authentication through Clerk supports social sign-in and multi-factor authentication; Mapster does not store passwords. Its infrastructure providers are SOC 2 Type II certified, with DDoS protection and automatic HTTPS. The company is subject to New Zealand's Privacy Act 2020 and, where applicable, GDPR and other privacy laws.

Pricing

Mapster has a free plan and three paid monthly tiers. All plans include unlimited surveys and all features, so the main distinction is response capacity; the free plan also carries Mapster branding.

The free tier is unusually complete on features, but 50 monthly responses is a tight ceiling for ongoing collection. When a plan reaches its monthly limit, surveys pause collecting new responses until the cycle resets or the account upgrades, so teams should choose a quota with headroom. Pro's unlimited allowance is qualified by fair use. Plans include email and chat support.

Platforms

Mapster is available on the web. Its website, in-product, link, embed, and widget channels make it relevant to teams collecting feedback across digital touchpoints, though the listed platform is web.

Who it's for

Mapster is aimed at SaaS founders, solo or lean product managers, and early-stage product teams under 20 people. Its segmentation and scoring can help these teams turn feedback into product signals without separating collection, analysis, and integrations across tools. It is not intended for enterprises that require multi-tenant access controls, SSO, audit logs, or a dedicated account manager.

Pros and cons

Pros

• All features across every tier: Users do not have to move to a higher plan for branching, scoring, or integrations; they pay primarily for response capacity.
• Responses can be analyzed by customer attributes: Linking widget answers to user and account details makes segmentation more actionable for product teams.
• Multiple ways to distribute and route feedback: Link, embed, and widget distribution pair with Slack alerts and broad Zapier connections.

Cons

• Collection stops at the monthly quota: Even the free plan pauses surveys at its cap, which can interrupt feedback collection until reset or upgrade.
• Enterprise controls are outside its target: Teams requiring SSO, audit logs, multi-tenant controls, or a dedicated account manager should look elsewhere.
• Pro's unlimited responses still have a fair-use condition: High-volume buyers should account for that qualification rather than treating the tier as unbounded.

Alternatives

Formbricks is worth comparing if a team wants a free option with a 250-response monthly Hobby plan or needs platforms beyond web, including mobile, API, or self-hosted options; its Pro plan is $89 a month (billed monthly).

Fynzo Survey may suit readers prioritizing broad survey authoring: its free plan includes unlimited surveys, questions, and responses, plus more than 1,000 templates.

Refiner is another freemium option, with a free plan providing 25 survey responses per month after a trial ends or a paid subscription is cancelled.

SatisMeter offers a free plan with 25 responses per month and a recommendation of about 250 active users, which may suit a smaller feedback program.

Thermostat has a free plan limited to one user and one survey, with 200 surveys administered per month and four months of response history.

Survicate may be a fit for a small team seeking a free allowance of 25 responses per month, three teammates, and 300 responses across active surveys.

Customer Thermometer has a paid model despite offering a free plan; its At the Beach tier costs $9 a month and retains and displays account data with zero responses.

Zonka Feedback is an alternative with custom-quote pricing based primarily on data credits, which can be bundled with Feedback Management.

Verdict

Mapster is a compelling choice for a SaaS founder or lean product team that wants segmented survey responses, scored feedback templates, branching, and integrations in one web tool. Its all-feature plans keep capabilities accessible at the lower tiers, but response pauses at quota limits and the lack of enterprise access controls make it a poor fit for high-volume or enterprise-wide programs.
