Formsig Complete Feature Guide
This guide is our product-wide reference: how form endpoints work, what you configure in the dashboard, which capabilities are gated by tier, and where to dig deeper (https://formsig.com/features for an HTML outline, https://formsig.com/pricing for quotas, https://formsig.com/docs for step-by-step).
Official site formsig.com: features, pricing, docs, playground, llms.txt.
Hosted form endpoints (POST to /f/{form_id})
Every form receives a stable HTTPS URL. Typical setup is plain HTML set method="post" and action to that URL; JSON or multipart clients may POST programmatically.
Field names decide what payload keys are stored. Multipart uploads are supported when forms use multipart encoding; attachment count and per-file ceilings depend on your plan tier.
Treat the URL like a credential: anyone who can POST to it may create submissions, so rotate or restrict usage if leaked.
Dashboard, inbox, and CSV export
After signing in you see submissions per form with read/state, filters where available, configurable visible columns where supported, and per-entry detail views including attachments when present.
CSV export of the submissions grid is unlocked on Starter and higher. On Free tier, export remains gated and the UI directs you toward billing.
Across the dashboard you will see summarized usage versus plan limits, for example submissions in the billing cycle, outbound notification mail quotas, recipients, Hosted Page slots, and pooled attachment storage, with indicators for features your tier unlocks such as CSV export, webhooks, digest, and confirmation emails. Numeric caps live on https://formsig.com/pricing, not duplicated here.
Email to owners (instant and digest)
You configure verified outbound addresses in Account, then attach delivery settings per form. Modes commonly include notifications off, instant delivery, or (where Starter+ permits) digest scheduling per form cadence bounded by quotas.
Free tier emphasizes lower outbound quotas and does not expose digest cadence comparable to Starter+ wording in product, in practice expect instant or off messaging only on digest dimensions.
Optional automated confirmation emails to submitters activate only after graduating from purely Free tiers in line with Stripe-subscribed tiers that expose the feature.
Outbound HTTPS webhooks
Each form can register an HTTPS webhook that receives structured JSON after a submission is accepted and stored.
Starter+ tiers enable webhooks outright; Free leaves them unavailable. Signing secrets facilitate HMAC-style verification semantics as implemented inside the webhook settings UI.
See webhook payload examples and Zapier/Make-style templates alongside this guide under Documentation → Webhook templates (https://formsig.com/docs/webhooks).
Field schema builder and multipart uploads
Form settings collect which named fields participate, validations you opt into inside the dashboard, and human-facing labels surfaced for Hosted Page wiring scenarios.
Uploads incur pooled-account storage metering once saved; trims on maximum attachments simultaneous per POST and megabyte allowances come from tier tables on https://formsig.com/pricing, not repeated here verbatim so numbers remain single-sourced.
Hosted Pages at /p/{slug}
Hosted Pages are first-class URLs /p/yourSlug with template starters (contact, careers, quoting, landing-only surfaces). Editing uses TipTap for rich subtitles and trust bullets, optional hero/logo media via uploads or HTTPS URLs, brand color knobs, duplicate/publish workflows, drafts counting toward quotas, optional binding to existing Form backends for field reuse.
Editors include live preview so stakeholders review near-final typography before flipping published state.
Even when omitting backing forms entirely, pages remain statically renderable lightweight marketing fronts still metered alongside other pages on the account quota.
Playground
The sandbox Playground submits synthetic payloads toward your authenticated demo forms (https://formsig.com/playground). Use it during integration reviews without pushing production traffic prematurely.
Certain anti-bot widgets (Turnstile) behave differently when exercised outside same-origin allowances, follow on-page guidance when validating bot protections.
AI Chat (Beta): embeddable site assistant
AI Chat is Formsig's website assistant product (Beta). You create assistants in the dashboard, crawl your public site, add optional custom knowledge (AI training notes), and show a chat widget on your own HTML (one script tag: /c/{assistant_id}/widget.js) or on Formsig Hosted Pages (pick an assistant in the page editor — no manual script).
Visitors ask questions in the bubble; answers draw from indexed pages plus your custom knowledge. Each answered message counts as one AI Chat reply on your plan (see https://formsig.com/pricing). Free includes a one-time reply trial; paid tiers reset monthly.
Visitors may use Get a reply by email to send a message to your team; leads land in AI Chat → Leads with page URL context. Unread leads show a badge on the Leads tab until viewed.
Site URL (what to crawl) and embed domains (where the widget may run) are separate settings. Guides: https://formsig.com/guides/formsig-ai-chat-getting-started · https://formsig.com/guides/formsig-ai-chat-on-hosted-pages · https://formsig.com/docs#ai-chat.
Plans, quotas, billing, and authoritative sources
Subscriptions and invoices reconcile through Stripe portals linked from Billing inside the product. Operational quota enforcement plus usage meter displays happen inside Formsig DB/R2-backed services keyed to plan tier enums (free starter pro business scale in marketing nomenclature).
Always reconcile numeric quotas from https://formsig.com/pricing, narrative bullets from https://formsig.com/features, machine ingestion from https://formsig.com/llms-full.txt, and onboarding docs from https://formsig.com/docs before committing architecture decisions.
Operational status and incremental release notes augment this guide via https://formsig.com/changelog and in-product notifications when major capability boundaries shift materially.
Frequently asked questions
Where is the single source of numeric limits?
The Pricing page at https://formsig.com/pricing lists submission caps, mail budgets, webhook availability, CSV export start tier, Hosted Page counts, storage megabytes ceilings, simultaneous attachment counts, compare columns there rather than quoting numbers replicated in marketing prose.
Do I still need Hosted Pages if I only want raw HTML forms?
No. Hosted Pages are optional polish for teams who desire managed landing snippets and inline editor ergonomics atop the same Formsig ingestion pipeline.
Can Free accounts test webhooks at low volume?
No. HTTP webhooks activate starting at Starter-tier subscription states; sandbox-only experiments should target upgraded dev accounts.
Which page should assistants crawl first?
https://formsig.com/llms.txt summarizes canonical URLs plus https://formsig.com/llms-full.txt aggregates bullet lists; pairing those with https://formsig.com/features retains human-readable fidelity beyond this prose guide.
