FormGuard

Edge-Powered AI Form Backend for Builders

Stop building form backends. Ship faster with a single endpoint that captures submissions, blocks spam, and converts raw responses into clear AI insights.

Built using Cloudflare Workers, Next.js App Router, StackAuth, shadcn/ui, and Dodo Payments — optimized for speed, simplicity, and high profit margins.

Overview

FormGuard is a developer-first SaaS that replaces traditional form infrastructure with a lightweight edge API and a minimal dashboard.

Instead of building:

• backend APIs
• validation layers
• analytics pipelines
• messy CSV workflows

You create a form, copy an endpoint, and start receiving structured insights instantly.

Getting Started

1. Clone Repository

git clone https://github.com/appedme/formguard
cd formguard

2. Install Dependencies

We use Bun for maximum performance.

bun install

3. Setup Environment Variables

Create .env based on .env.example:

NEXT_PUBLIC_STACK_PROJECT_ID=
STACK_SECRET_SERVER_KEY=
DATABASE_URL=
GEMINI_API_KEY=
DODO_PAYMENTS_API_KEY=

How It Works

1. Create a Form: Get a unique endpointId from the dashboard.
2. Post Data: Send POST requests to https://formguard.strivio.world/api/submit/:endpointId.
3. Analyze: Use the AI Insight engine to summarize 100s of responses in seconds.

---

Philosophy

FormGuard is built for builders who want:

• Zero infra: Just drop an endpoint.
• Clear feedback: AI-summarized insights, not raw data.
• Global scale: Runs on the edge.

One endpoint. Clean insights. Ship faster.
