SaaS Starter (stickerdaniel)
A SvelteKit + Convex SaaS starter built for AI-agent-assisted development

- Best for
- Developers who want a SvelteKit + Convex SaaS stack with billing, an admin panel, and AI support chat already built, especially if coding with an AI agent.
- Skip if
- You want a more established/larger-community starter - this one is small (51 stars) and newer.
An open-source SaaS template pairing SvelteKit with Convex as a serverless backend/database, using Better Auth for authentication with passkeys and OAuth, and Autumn + Stripe for billing. It ships an admin panel with audit logs, AI-powered support chat, Resend-based transactional email, i18n across four languages, real-time updates, PostHog analytics, and dynamic SEO sitemaps, styled with shadcn-svelte.
Pros
- Unusually broad feature set for a free starter: AI support chat, i18n, real-time updates, audit logs
- Built with AI-agent-assisted development in mind, with regression guards and type safety
- Multiple deploy targets - Cloudflare Workers, Vercel, or self-hosted via Coolify
- MIT licensed and free
Cons
- Small community (51 stars, 26 open issues) - less battle-tested than larger starters
- Convex as the backend is a specific commitment, less flexible than a plain Postgres setup
- Newer project - long-term maintenance track record not yet established
