Features
Every feature. One plugin.
SIForm covers the whole life of a form — building it, filling it in, getting paid, booking the time, sending the right email and following up — without a single add-on.
Builder
Build visually, on a real canvas.
Drag fields into rows and columns, split a form into steps, and see it on desktop, tablet and mobile while you work.
- Rows and columns with drag-and-drop
- Multi-step forms with progress indicators
- Undo, redo and saved versions you can restore
- Live desktop, tablet and mobile preview
- One question at a time — the same form, as a conversation
- Command palette and keyboard shortcuts
Fields
60 field types, plus 9 advanced.
From a single line of text to products, bookings, maps and signatures. Every field has validation, conditional logic and its own design settings.

Logic & data
Forms that react to every answer.
Show, hide, require or disable fields, steps and the Submit button. Price or score anything with a safe formula engine, and fill fields from the page, the user or another form.
- Conditions with AND / OR groups
- Skip whole steps, or send different emails, by answer
- Calculated fields with live totals
- Pre-fill from the URL, the logged-in user or earlier answers
- Lookups and options pulled from posts, users or another form
show “Rush fee” when Deadline < 14 days
require “Company” when Type = Business
skip step 3 when Plan = Free
({service} + {pages} × 90 + {extras}) × {speed}

Security & control
Safe by default.
Spam checks are on for every form. Add CAPTCHAs, limits and restrictions when you need them.
Spam protection
Honeypot and timing checks, reCAPTCHA v2/v3, hCaptcha, Cloudflare Turnstile, Akismet, CleanTalk, Stop Forum Spam, disallowed words and country rules.
Access & limits
Require login or a role, protect with a password, open and close on a schedule, and limit entries per email, browser, IP or user.
Accounts & content
Sign-in and registration forms with activation or approval, posts created from entries, and content unlocked after sending.
Privacy & GDPR
Consent fields, encrypted API keys, and personal-data export and erase through WordPress’s privacy tools.
Workflows & integrations
Automate what happens next.
Workflows run on your server after a submission, a payment, a booking change or an edit. Integrations send mapped answers to 67 apps, with a log of every delivery.
- Triggers: submitted, paid, booking confirmed, cancelled or moved, entry edited
- Steps: email, webhook, delay, branch, task, Slack, Discord, SMS
- Approval chains with comments and history
- Retries and a delivery log for every integration
