Questions About Retool
Best AI app builders for non-developers 2026
For non-developers building AI apps in 2026, the leading low-code platforms are Bardeen, Lindy, Gumloop, Relevance AI, and n8n on the workflow side, with Retool and Supabase as the closest "no-code adjacent" options for builders willing to write a small amount of SQL or JavaScript.
How to set up Supabase Edge Functions for AI workloads
Create the function with `supabase functions new ai-handler`, write a Deno handler that reads the user JWT, calls a model provider, and writes results back via the Supabase client with row-level security. Deploy with `supabase functions deploy ai-handler` and call from the frontend using `supabase.functions.invoke()` with the user's session token.
Retool vs Budibase: which internal tool builder should you choose?
Retool is the market leader for internal tool builders with 100+ integrations, strong SQL and JavaScript support, and SOC 2 compliance; it targets mid-market to enterprise. Budibase is open-source, self-hostable, and more cost-effective for smaller teams or data-sensitive organizations. Retool wins on ecosystem and polish; Budibase wins on licensing flexibility and self-hosting.
What are the best Supabase alternatives in 2026?
The top Supabase alternatives in 2026 are Firebase (Google's BaaS with real-time database), Retool (internal tool builder with database integration), and Airtable (no-code database with automation). Firebase offers the closest feature match for real-time applications, while Retool suits teams building internal dashboards and admin panels.
