Forms.md Builder
Build production-ready, Typeform-style forms using the Forms.md library.
Quick Start
- Create an HTML file with Forms.md boilerplate
- Write form content in the DSL (Markdown-like syntax)
- Add Typeform-style CSS theme for polish
Boilerplate Template
<!DOCTYPE html>
<html lang="en" class="fmd-root" data-fmd-color-scheme="light">

Form Content DSL
Settings block (top):
#! title = Survey Title
#! post-url = /api/submit
#! accent = #6366f1
#! rounded = pill
#! button-alignment = center
Slides separated by ---:
# Welcome!
Ready to get started?
---
-> start -> Let's go!
name* = TextInput(
| question = What's your name?
| placeholder = Enter your name
)
---
role* = ChoiceInput(
| question = What's your role?
| choices = Developer, Designer, Manager, Other
)
---
-> role == "Other"
roleOther* = TextInput(
| question = Tell us about your role
)
---
email* = EmailInput(
| question = Your email?
| description = We'll send you the results
)
---
-> end
Key Syntax
| Element | Syntax |
|---|
| Required field | name* (asterisk) |
| Slide separator | --- |
| Logic jump | -> condition |
| Start slide | -> start |
| End slide | -> end |

Common Patterns
Conditional slide (show based on previous answer)
---
-> previousField == "specific_value"
Conditional field within slide
::: [{$ triggerField $}]
{% if triggerField == "Other" %}
otherField = TextInput(| question = Please specify)
{% endif %}
:::
Rating + Follow-up
rating* = RatingInput(
| question = How was your experience?
| outof = 5
)
---
-> rating <= 2
feedback = TextInput(
| question = What could we improve?
| multiline
)
Output
Generate a single .html file containing:
- Forms.md CSS (CDN or inline)
- Forms.md JS (CDN or inline)
- Typeform-style theme CSS
- Form template in the DSL
The form works client-side only - just open the HTML file or deploy to any static host.
Collecting Form Submissions
To collect and store form responses, set up the backend using the Forms API.
Complete Workflow
- Create form backend - Call the Forms API to create storage
- Build the HTML form - Use the
submitUrl in the form's post-url
- Deploy the form - Host the HTML file anywhere
- View results - Use the
resultsUrl to see submissions
Step 1: Create Form Backend
POST https://api.rebyte.ai/api/forms/create
Content-Type: application/json
{
"taskId": "current-task-attempt-id",
"title": "My Survey",
"fields": ["name", "email", "rating", "feedback"]
}
Response:
{
"formId": "abc123",
"taskId": "current-task-attempt-id",
"submitUrl": "https://api.rebyte.ai/api/forms/submit/TASK_ID/FORM_ID",
"resultsUrl": "https://api.rebyte.ai/api/forms/results/TASK_ID/FORM_ID"
}
Step 2: Configure Form HTML
Use the submitUrl from the response in the form's settings:
#! post-url = https://api.rebyte.ai/api/forms/submit/TASK_ID/FORM_ID
Step 3: Provide URLs to User
After creating and deploying the form, give the user:
- Distribution URL: Where the HTML form is hosted (for respondents)
- Results URL: The
resultsUrl from Step 1 (for viewing submissions)
Viewing Results
- JSON:
GET https://api.rebyte.ai/api/forms/results/TASK_ID/FORM_ID
- CSV:
GET https://api.rebyte.ai/api/forms/results/TASK_ID/FORM_ID/csv
