OneTimeNPS, CSAT and CES surveys you own forever.
Delighted charges $224 a month to ask your customers one question and store the answers in their cloud. Pulsecheck does the same NPS, CSAT and CES capture on your own server, with detractor alerts and per-segment breakdowns. $29, once. It is subtraction.
Pulsecheck in 60 seconds
Everything in the box
One-question surveys by link, email or widget with instant detractor alerts, self-hosted.
Three survey types
NPS (0-10), CSAT (1-5) and CES (1-7), each with correct documented score math (NPS = %promoters minus %detractors, ranged -100 to 100).
Three delivery channels
A standalone survey link, personalized email sends via your own SMTP, and an embeddable widget script.
One response per recipient
Email-keyed dedupe at the database level means a second submit gets a friendly already-responded message.
Detractor alerts
A Slack-ready webhook and/or email fire instantly on low scores, and soft-fail so they never block response capture.
Dashboard
Score trend over time, the promoter/passive/detractor split, and a response feed with comments.
Segments
Pass tags like plan:pro with responses and get per-segment NPS breakdowns.
XSS-safe by construction
The public survey page escapes every user-controlled string and the widget renders via textContent only.

One payment of $29 gets the packaged Windows installer, or clone the MIT source at github.com/bensblueprints/nps-survey-tool-mvp and run it yourself for free.
Deploy or run desktop

Fair questions
Is it really free on GitHub?
Yes, Pulsecheck is MIT-licensed at github.com/bensblueprints/nps-survey-tool-mvp. The $29 buys the packaged Windows installer and 1-click setup; building from source is free.
Where do my responses live?
In a SQLite file on your own server. It is 100% local, with no telemetry and no response caps.
Is this a subscription in disguise?
No. $29 once, no renewal, no monthly response limit.
