runsyour server
installInstall and activate the Forminator plugin from WordPress Admin
dataForms and submissions are stored in the site's WordPress database; uploaded files are stored in WordPress uploads, and submissions can be exported as CSV.
the catch vs OutgrowForminator can build formula-driven quizzes and calculators, but it requires WordPress and offers less polished outcome templates, lead segmentation, and conversion reporting than Outgrow.
setupIt only runs inside an existing WordPress site, so hosting, WordPress maintenance and mail delivery must already be solved.

licenseFSL-1.1-Apache-2.0
runsyour machine or their cloud
installHosted signup, or Docker Compose/manual deployment of builder and viewer

dataHosted bots and results live in Typebot Cloud; self-hosted data lives in PostgreSQL and uploaded files in S3-compatible object storage.
the catch vs OutgrowTypebot can calculate and branch without per-lead fees, but its conversational presentation is not as purpose-built for polished calculators, result pages, and conversion analytics as Outgrow.
setupSelf-hosting requires PostgreSQL, S3-compatible storage, two web apps, DNS/TLS and mail/auth configuration; the licence is Fair Source rather than OSI open source.

People still pay for Outgrow because a basic form is trivial; people pay when the form feeds a dependable business workflow and never loses a response. The recurring cost buys spam control, email delivery, storage, exports, accessibility, conditional logic, and integrations, not just the visible interface. If none of that applies to you, any pick above saves $264 a year.
Is there a free alternative to Outgrow?
Yes: Forminator, Tally, Typebot. Every tool on this page is either open source or genuinely free to use long-term: no trials, no crippled tiers.
Should I just build my own Outgrow?
Our verdict is PARCIAL. The core loop is buildable, but a dependable replacement becomes a real weekend or multi-day project. For Outgrow, create a constrained calculator or quiz with formula-driven results. The hard boundary is template library, lead capture, analytics, integrations, and hosted embeds, plus integrations, deliverability, and workflow depth. If you'd rather build, the exact one-shot prompt is free at puedovibecodearlo.app/outgrow.
