Why AI Apps Break on Standard Hosting

AI-powered applications — whether built with OpenAI, Anthropic, Replicate, or open-source models — have fundamentally different infrastructure needs than traditional web apps. LLM API calls take 10–90 seconds. Image generation can take minutes. Embedding pipelines process thousands of records in batches. Retrieval-Augmented Generation (RAG) queries need vector searches combined with LLM inference.

Serverless platforms like Vercel and Netlify have hard timeout limits (10–60 seconds depending on plan). Usage-based pricing means a spike in AI API usage translates directly into a spike in your hosting bill. And there's no native support for background workers, queues, or async processing.

What AI Apps Actually Need From Their Host

  • No timeout limits — LLM calls, image generation, and batch processing run to completion
  • Background worker support — Queue AI jobs and process them asynchronously, outside HTTP request cycles
  • Webhook handlers — Receive and process AI callbacks and results from async providers
  • Cron job scheduling — Run embedding refresh jobs, data sync pipelines, and model evaluation on schedule
  • Flat pricing — A busy AI app shouldn't generate a surprise $500 hosting bill
  • Supabase integration — Store embeddings, results, and user data with built-in Supabase support
  • Email & SMTP — Notify users when long-running AI jobs complete

AI App Patterns SupaDeploy Handles

Async LLM processing

Accept user requests, queue LLM calls in the background, and notify users via email or webhook when results are ready.

Embedding pipelines

Generate and refresh vector embeddings for RAG applications on a schedule or triggered by document uploads.

Image & media generation

Queue image generation jobs, poll for results, and deliver to users without blocking the UI thread.

Data ingestion & indexing

Process large document uploads, crawl URLs, extract structured data, and store results in Supabase.

Model evaluation pipelines

Run scheduled evaluation jobs to benchmark your AI outputs and detect regressions automatically.

AI-triggered notifications

Use the built-in Email & SMTP service to send results, alerts, and summaries generated by AI workers.
