Supabase

Content Moderation with Supabase

Drop moderation into your Supabase stack.

Edge Functions, Database Webhooks, and Realtime patterns.

What it detects

  • • Insert payloads via webhooks
  • • Edge Function inputs
  • • Realtime broadcast events
  • • Storage uploads
  • • Auth signup metadata
  • • Custom rules

Why developers choose Vettly

  • • Edge Functions run the SDK natively
  • • Database Webhooks trigger checks on insert
  • • Persist decisions in Postgres for audit
  • • Pairs with RLS for tenant-aware moderation
Example request
bash
// supabase/functions/moderate-comment/index.ts
import { Vettly } from 'npm:@vettly/sdk';

const vettly = new Vettly({ apiKey: Deno.env.get('VETTLY_API_KEY')! });

Deno.serve(async (req) => {
  const { content, user_id } = await req.json();
  const result = await vettly.check({ content, contentType: 'text', policyId: 'comments' });
  if (result.action === 'block') {
    return new Response(JSON.stringify({ blocked: true }), { status: 400 });
  }
  return new Response(JSON.stringify({ ok: true }));
});
Example response
json
{
  "flagged": true,
  "action": "block",
  "categories": {
    "harassment": 0.93,
    "hate": 0.02
  },
  "policy": "default",
  "latency_ms": 142
}

Compared to building moderation in Postgres triggers

Edge Functions give you a clean place to call Vettly without putting HTTP calls inside SQL triggers.
