Picking customer feedback and analytics tools for a small SaaS is mostly a question of which gap hurts most: you do not know what users do, you do not know why they do it, or you do not know which marketing effort produced a lead. Three tools cover those three gaps: Amplitude for product analytics, Survicate for surveys, and WhatConverts for lead and call attribution.

This is an informed guide built from each vendor’s public pricing and feature pages, checked in October 2026. I have not run these tools myself, so treat it as a research summary to shorten your shortlist, not a hands-on review.

Comparison table (checked October 2026)

Tool	Best for	Starting price	Free plan or trial	Key limit
Amplitude	Product usage analytics	$0 (first 2M events/month free)	Free plan, no card	1 active experiment and 1-year data access on Free
Survicate	In-product and email surveys	Starter from $56/month	10-day trial, no card	2 active surveys on Starter and Growth
WhatConverts	Lead, call and form attribution	$30/month (Call Tracking)	14-day trial	Usage beyond included credit is billed as overage

Amplitude: product analytics

What it is

Amplitude tracks what users do inside your product: clicks, page views, signups, purchases. You send events, then build funnels, retention charts and cohorts to see where people drop off or come back.

Key features and pricing

According to Amplitude’s pricing page, the Free plan has no time limit or card requirement and includes 2M events per month, 10K session replays per month, one active feature experiment and one active web experiment, and one year of data access. Plus starts at $0 with the first 2M events free, then scales by usage and requires a card. Growth and Enterprise are custom priced. Amplitude also lists a startup offer of a free year of Growth for companies with under 20 employees and under $10M in funding, so check eligibility on the site.

Billing is event-based. An event is any tracked user action, and a monthly tracked user (MTU) is a unique user who triggers at least one event in a month.

Pros and cons

• Pro: a real free plan with a generous event allowance for an early product.
• Pro: funnels, retention and cohorts without building your own warehouse.
• Con: it needs a clean event plan. Messy tracking gives messy charts.
• Con: the pricing page has small inconsistencies (for example, how it describes A/B tests on Free), so confirm limits before relying on them.

Skip it if you have no product to instrument yet, or if nobody on the team will own the tracking plan.

Survicate: surveys inside and outside the product

What it is

Survicate runs surveys on your website, inside your app and by email. It is the “why” tool: NPS, churn questions, onboarding feedback and feature requests collected where users already are.

Key features and pricing

Survicate offers a 10-day free trial with no card required. Per its pricing page, Starter starts at $56/month (500 responses per month), Growth at $114/month billed annually, Pro at $349/month and Enterprise at $569/month. Starter and Growth allow 2 active surveys and 6 months of data retention; Pro adds unlimited active surveys and 2 years of retention. The page shows conflicting figures for the Growth plan limits, so verify them on the current pricing page. I could not confirm a permanent free plan, so check the current price and plan list on the official pricing page.

Pros and cons

• Pro: surveys can sit inside the product, which usually gets answers from people who are actually using it.
• Pro: integrations with common tools are listed on the vendor site.
• Con: prices are response-based, so a busy product can hit limits.
• Con: two active surveys on lower plans is tight if you run several tests.

Skip it if your user base is tiny enough that you can simply email ten customers and ask.

WhatConverts: lead and call attribution

What it is

WhatConverts records which marketing source produced each lead, whether it came as a phone call, a form fill, a chat or a transaction. It suits SaaS teams that run paid search or sell with a phone or demo-request step.

Key features and pricing

Every plan has a 14-day free trial. Single-account plans on the pricing page are Call Tracking at $30/month, Plus at $60, Pro at $100 and Elite at $160. Call Tracking covers call tracking and recording and dynamic number insertion; Plus adds forms and chat with campaign and keyword reporting; Pro adds call flows and a report builder; Elite adds customer journey and multi-click attribution. Agency plans start at $500/month. Overages are billed separately, for example 10 cents per extra form, chat or transaction and 4.5 cents per extra local minute on single-account plans. WhatConverts lists HIPAA-compliant tracking on Pro, which is the vendor’s claim, so confirm it for your own needs.

Pros and cons

• Pro: low entry price and a clear plan ladder.
• Pro: ties leads to campaigns and keywords, which product analytics alone cannot do.
• Con: included usage is capped, so overages matter as volume grows.
• Con: the page does not fully explain how the usage credit is consumed, so use its calculator.

Skip it if you are fully self-serve with no sales calls and no paid ads. Product analytics will serve you better.

How to choose

• No idea where users drop off: start with Amplitude.
• You see the drop-off but not the reason: add Survicate.
• Leads come in but you cannot tell which channel worked: choose WhatConverts.

If budget is tight, begin with the free Amplitude plan or one of the trials, then add a second tool only when a specific question keeps coming up. Survey and call tools are cheap to test; the real cost is the time to act on the answers. If you already compare survey tools, my guide to SurveyMonkey vs Google Forms covers the basic form options.

How it fits with a Notion workflow

None of these tools plans your work. A common pattern is to export insights into a Notion workspace: a feedback database for survey themes, a roadmap table for features, and a leads log for sources. The Small Business Back Office Kit gives you the admin structure, and the Project Manager Toolkit helps turn findings into scheduled work. For setup ideas, see the complete guide to Notion for project management. The templates organise decisions; the tools above supply the data.

FAQ

Can a small SaaS use all three together?

Yes, but sequence them. Each answers a different question, and running all three at once usually creates more data than you can act on.

Is Amplitude really free?

Amplitude states that its Free plan has no time limit and no card requirement, with limits such as 2M events per month. Confirm the current limits on its pricing page.

Does Survicate have a free plan?

It advertises a 10-day free trial with no card. I could not confirm a permanent free plan, so check the official pricing page.

Do I need WhatConverts without phone calls?

Not necessarily. Its value is strongest when calls, forms and paid campaigns drive leads. If your product is fully self-serve, analytics and surveys come first.

Final verdict

For most small SaaS teams, start with Amplitude to see behaviour, add Survicate when you need reasons, and bring in WhatConverts when marketing attribution becomes the question. Prices change, so check each pricing page before you commit.
