Quick answer: Delighted starts cleanest; Survicate stretches beyond NPS into full survey territory; AskNicely turns responses into CS workflows; Qualtrics is the enterprise research suite that includes NPS the way a hospital includes band-aids. And the in-app path — PLG OS included — treats NPS as one prompt type inside your product's engagement layer, governed by the same eligibility and frequency rules as everything else you show users. The vendor matters less than the discipline; the discipline is the part most teams skip.
Where the survey reaches users (email, link, in-app), what happens after a response (workflows, routing, or a dashboard nobody opens), eligibility and cooldown controls, and pricing shape by response volume. Pricing as shapes, September 2026 — verify live; survey tools reprice quietly and often.
| Tool | Reaches users via | Best for | Pricing shape |

| AskNicely | Email, in-app | CS teams working responses | Quoted |
| Qualtrics | Everything | Enterprise research programs | Enterprise quoted |
| InMoment/Wootric-class | In-app, email | CX programs at scale | Quoted |
| Typeform | Link, embed | Beautiful occasional surveys | Monthly tiers |
| PLG OS | In-app, native | NPS inside the engagement layer | Published tiers |
Delighted (a Qualtrics company) remains the cleanest way to stand up email/link NPS this week — sensible defaults, honest tiers, no consultant required. Survicate wins when NPS is one survey among many — onboarding feedback, feature polls, churn reasons — one tool for all of it. AskNicely is built for the team that treats every detractor as a ticket: routing, follow-ups, closing the loop as workflow, not intention.
Qualtrics and the Wootric/InMoment class serve enterprise CX programs — panel management, statistical tooling, price tags to match; right when research is a department, heavy when it's a metric. Typeform appears because teams keep using it for NPS: gorgeous surveys, but eligibility, cooldowns and trend infrastructure are yours to build around it.
PLG OS — ours, same rules as everyone — makes the in-app argument: NPS is a prompt your product shows, so it should obey the same eligibility, targeting and frequency budget as every other prompt, share the user graph with your onboarding and gamification state, and never interrupt a user mid-task. That's the fit when in-app is your primary surface; if your NPS program is email-led to buyers who rarely log in, an email-first tool above fits better. Either way, run the program on written rules — our NPS eligibility and cooldown worksheet is the one-pager that outlives the vendor choice.
Ask each vendor: "What's the response rate difference between your in-app and email delivery for products like ours, and what eligibility controls prevent us from burning users to get it?" In-app NPS reliably outdraws email — which is exactly why it needs governance: the channel that converts best is the channel that annoys fastest when ungoverned. A vendor who quotes the rate without the controls is selling you this quarter's chart and next quarter's prompt fatigue — the prompt frequency budget is the governance the number needs.
What is the best NPS software?
Delighted (fast start), Survicate (multi-survey), AskNicely (CS workflows), Qualtrics (enterprise research), PLG OS (in-app, inside the engagement layer). Match the tool to where your users actually are.
How often should NPS run?
Quarterly max per user with response/dismissal cooldowns; continuous small samples program-wide. The worksheet linked above pins the exact rules.
Is NPS still worth it?
As your own trend line plus verbatims, yes. As a cross-company scoreboard, no — methodology differences swamp the signal.
