The verdict Side by side Plans and pricing Who each is for Other options

The verdict

If you build software and want to ask users a question next to the behaviour data you already collect, pick PostHog. You get analytics and surveys on the same platform, and an engineer can set it up. If you need a standard research job, such as NPS, an employee pulse, event feedback or a market study, pick SurveyMonkey. Marketing, HR and operations can run it without a developer. A small B2B software team with an engineer will probably want PostHog for its product questions and SurveyMonkey only when it needs wider customer or staff research. Do not install PostHog just to send surveys.

Who each is for

Choose PostHog if…

PostHog suits B2B product and engineering teams that want analytics, replay, flags and surveys on the same data. Someone has to install the SDK and own the event plan, so it is the wrong choice for a marketing team with no engineering help. It rewards teams that start with one or two modules and grow. Pricing is based on usage per product, with a free allowance on each, so set billing limits. Most teams should run PostHog Cloud, since self-hosting is real work. A free hosted MCP server lets a coding agent query the data from an editor.

Choose SurveyMonkey if…

SurveyMonkey suits B2B teams in marketing, HR and customer experience who want a reliable, familiar survey tool and a fast route from question to chart. Respondents know the format, and reports can be filtered and exported. It connects to Salesforce, Power BI and Tableau, and it has an official Claude connector and MCP server. Watch the tiers. Features, response volumes and seats rise by plan, and extra responses cost more, so estimate yearly responses before choosing. It is a poor fit for rigorous academic research or a form that feeds your own database. For those, compare Typeform or Tally.
