Mapster
Mapster is an in-product survey tool that fires NPS, CSAT, CES and PMF questions at the moment users act, then ties every answer to a real account so results can be segmented by plan, role, cohort or country.
What is Mapster?
Mapster is a customer feedback survey platform built around a single idea: knowing who answered matters as much as what they said. Surveys fire inside the product itself, at moments the host application chooses, and every response arrives carrying the identity that application passed with it. Email, plan, role, company, tenure and country travel alongside the answer, together with any custom attribute and behavioural context such as whether the respondent is a power user, how many exports they have run, or whether they have just hit a plan limit. The stated result is the difference between "100 users are happy, 40 are unhappy" and knowing that the unhappy ones are free-plan users in a specific country complaining about pricing.
The builder covers thirteen or more question types, from text and multiple choice to star ratings, emoji scales, NPS and age brackets, and ships with fifty ready-made templates grouped by stage: validation, marketing attribution, NPS, CSAT and CES, product-market fit, product feedback, user research, customer experience, churn and exit, customer success and pricing. An AI generator will draft the questions from a described goal. Logic jumps route respondents by answer option or by score bucket, so detractors can be sent to a follow-up while promoters reach a different closing screen.
Delivery is flexible: a popup widget triggered by time, scroll depth or exit intent, a sticky feedback button, a manual JavaScript call, a shareable link, or an HTML embed. Analytics update in real time and include per-question breakdowns, automatic classification into Promoters, Passives and Detractors, word clouds over open text, rating trends and an interactive world map that drills from country to city. Duplicate and bot submissions are filtered using a salted per-survey hash of the IP address and Cloudflare Turnstile.
Slack receives responses through incoming webhooks; Zapier connects the rest. Every feature is included on every plan, including the free one, which differs only by monthly response volume. The publisher is Galaxy Labs Limited, a New Zealand company.

When to use Mapster / When not to
A quick filter to help you decide if Mapster is the right fit.
When to use Mapster
- SaaS product teams that need NPS, CSAT or PMF broken down by segment rather than reported as one blended score
- Startup founders running the Sean Ellis product-market fit test against the 40% benchmark
- Customer success and support leads measuring satisfaction after onboarding, after a ticket, or at the point of churn
- UX and user researchers who want friction captured in the moment instead of reconstructed days later
- Growth and CRO specialists running exit-intent, pricing-page and marketing-attribution surveys on a small budget
When not to use Mapster
- Teams that need a documented public API to drive surveys programmatically, since only a JavaScript widget, Slack and Zapier are offered
- Companies requiring native two-way CRM sync with HubSpot, Intercom, Salesforce or Segment, which the site openly says it does not provide
- Mobile-first products expecting a native iOS or Android SDK, as there is no Mapster app and in-app surveys run through the web widget
- Procurement teams with a hard compliance checklist, since Galaxy Labs Limited holds no security certification of its own and offers no data processing agreement
- Market researchers needing sampled, methodologically controlled panels, which the terms explicitly say survey results are not
How to use Mapster
A typical end-to-end flow, from setup to results.
- Create an account from the sign-up page; no credit card is required
- Pick one of the fifty templates, or describe your goal and let the AI generator draft the questions
- Assemble the questions from the thirteen or more available types and add intro and thank-you screens
- Set the branding: logo, colours, theme, font and corner radius, or let Mapster pull colours and logo from your website URL
- Add conditional logic, routing by answer option or by score bucket, with as many end screens as you need
- Install the widget on your site or inside your product with a single script tag, adjusting your CSP headers as documented
- Pass user attributes through JavaScript or URL parameters so responses can be segmented
- Choose the trigger: timed popup, scroll depth, exit intent, sticky button or a manual JavaScript call
- Alternatively share the survey as a link or paste the HTML embed if the widget does not fit
- Watch responses land in the real-time dashboard, filter by segment, then export to CSV or Excel and wire up Slack or Zapier
Pros & Cons
Pros
- Every feature is included on every plan, free plan included; only the monthly response volume changes
- A permanent free tier of 50 responses per month, with no credit card required
- No per-seat pricing, so cost does not climb with team size
- User identity attached to each response removes the export-and-pivot-table step before segmenting
- Low paid entry point at 19 USD per month, halved on annual billing
- Setup is a single script and is advertised at under ten minutes
- Security practices are documented and all seven subprocessors are named publicly
Cons
- No documented public API, which rules out programmatic survey management
- Native integrations stop at Slack and Zapier; there is no two-way CRM sync
- No Mapster mobile app or native SDK; in-app surveys rely on the web widget
- The free plan caps at 50 responses per month and keeps a Powered by Mapster link
- No security certification of Mapster's own: the SOC 2 Type II claims belong to Vercel, Supabase, Stripe and Clerk
- No data processing agreement, no Article 27 representative and no postal address published anywhere
- No stated retention period and no guaranteed hosting country or EU data residency option
Pricing & Plans
A permanent free plan is available at no cost, covering 50 responses per month with every feature included and no credit card required.

Data, GDPR & hosting
A consolidated view of how Mapster handles your data.
GDPR overview
Partial and informal. The privacy policy, last updated on 10 July 2026, states that Galaxy Labs Limited is subject to the New Zealand Privacy Act 2020 and, where applicable, to the GDPR; the terms add that mandatory local laws apply to EU users and that the company will comply with them. The substance is present: controller and processor roles are separated explicitly, and the policy grants access, correction, erasure, objection, portability and withdrawal of consent, pointing EU and UK residents to their local supervisory authority. What is missing is the paperwork an EU buyer usually asks for. There is no Article 27 representative, no named data protection officer, no data processing agreement and no dedicated GDPR page. Every request goes to a single address, contact@mapster.io.
Who owns the data?
Your surveys and the response data collected through them remain yours: the terms grant Galaxy Labs Limited only the licence it needs to host, process and display that data in order to run the service. The privacy policy then splits the roles. Galaxy Labs Limited is the data controller for creator account data, while for respondent data gathered through a creator's survey the creator decides what is collected and Mapster processes it on the creator's behalf. Responses are shown to the creator who ran the survey and to nobody else, never to other creators and never publicly, and the company states it does not sell personal data. A merger, acquisition or asset sale would transfer data, with notice.
Reuse rights
Reuse is unrestricted on the vendor's side. The terms state that you may export your survey data and use it for any lawful purpose, with no permission to ask for; exports come as CSV or Excel, filtered exports are supported, and individual responses can be deleted. The real limits are the ones you owe your own respondents rather than Mapster. Creators agree to handle survey data responsibly and in line with the privacy commitments they have made to their users, must obtain the necessary consents before collecting sensitive data such as demographics, and must never attempt to re-identify respondents who answered anonymously.
Data retention & training
Hosting summary
Mapster is operated by Galaxy Labs Limited, a New Zealand company; the terms are governed by New Zealand law with disputes heard in Auckland. Data sits in a managed Supabase PostgreSQL database, encrypted at rest with AES-256 and backed up automatically, while the application runs on Vercel's global edge network. Traffic is encrypted in transit over HTTPS with TLS 1.2 or higher. Seven subprocessors are named publicly: Vercel for hosting and delivery, Supabase for the database, Clerk for authentication, Stripe for payments, Mapbox for maps, Resend for transactional email and PostHog for product analytics. The privacy policy warns that providers may store and process data outside New Zealand, giving the United States as an example, with a commitment to safeguards comparable to the New Zealand Privacy Act 2020. No hosting country or region is guaranteed and no data residency option is offered. The SOC 2 Type II certifications cited belong to those infrastructure providers, not to Mapster itself.
Things to keep in mind
Risks and trade-offs to weigh before adopting Mapster.
- Respondents may not realise their answer is not anonymous: the product exists to attach a survey response to an identified person
- The compliance burden sits with the customer, who must hold a lawful basis for the attributes they pass and disclose the processing in their own privacy notice
- Every submission derives an approximate location from the IP address, down to city and postal code where available, alongside device, browser, OS and timing data
- Diagnostic logs may temporarily retain a raw IP address when a submission fails to save
- No retention period is published, so how long responses live is genuinely unknown
- Behavioural triggers make it easy to over-survey users until they stop answering, degrading the very signal the tool exists to capture
- Steering a roadmap by segmented scores can quietly replace listening with optimising a number
Setup & Integrations
Technical difficulty
Low to moderate, depending on how far you go. Building and sharing a survey needs no code at all: a visual builder, fifty templates, AI question generation, then a shareable link or an HTML embed. Installing the in-product widget is one script tag, advertised at under ten minutes, with a documentation page for the Content Security Policy headers it needs. The one step that requires a developer is segmentation: user attributes must be passed through JavaScript or URL parameters, which means a small change in your own application code. Slack connects by incoming webhook and Zapier needs no technical setup.

Should you pick Mapster?
Mapster does one thing and makes no secret of the fact that it does less than the suites it compares itself to. It puts a survey in front of a user at the moment that matters and hands back an answer with a name, a plan and a country attached, which is precisely the step most feedback tools leave to a spreadsheet. For a product team trying to work out whether its onboarding is failing enterprise accounts or only free-tier tourists, that is the whole value.
The commercial model is unusually legible. Every feature ships on every plan, including the free one, and only the monthly response volume is metered; there is no per-seat charge, so cost does not track headcount. Fifty responses a month for nothing, then 19 USD a month, halved on annual billing, puts it within reach of a solo founder measuring product-market fit.
The gaps are real and worth weighing. There is no public API, integrations stop at Slack and Zapier, and there is no native CRM sync — the site says so itself. On governance the picture is thinner still: no postal address anywhere, no data processing agreement, no Article 27 representative, no stated retention period, and no certification belonging to Mapster rather than to its infrastructure providers. A comparison page also still advertises prices the official pricing page contradicts, which reads as a young site rather than bad faith, but it is a reminder to trust /pricing over the marketing pages.
Recommended for small and mid-sized SaaS teams that want segmented in-product feedback quickly and cheaply. Buyers with a formal vendor-review process, or with EU data residency requirements, should ask Galaxy Labs Limited direct questions before committing.
