You have a map of the frozen lake. Every crack in the ice, every slippery patch, every hole is marked. You can sit at your desk and plan the perfect route before stepping foot on the ice. That is value iteration. Now imagine you have no map. You lace up your boots and start walking. You slip, you fall into holes, you backtrack. But each time you learn a little more about which moves pay off and wh
If your Flutter app offers any third-party login on iOS — Google, Facebook, anything — Apple's App Review guideline 4.8 forces you to also offer Sign in with Apple. That part is non-negotiable. .p8 keys, capabilities, entitlements, deep links — and most of it is only documented across three or four different Apple and Supabase pages that don't quite agree with each other. This is the guide I wis
Supabase Edge Functions run on Deno Deploy and are far more capable than simple REST handlers. This guide covers three advanced patterns every indie developer should know: streaming responses (for LLM integrations), WebSocket upgrades (for real-time features), and background jobs using EdgeRuntime.waitUntil. The most common use case is streaming LLM output without blocking the client. // supabase/
Supabase Realtime streams PostgreSQL changes to clients over WebSocket. Combine it with Flutter and you can ship live notifications, "who's online" indicators, and collaborative editing in dozens of lines of code. This guide covers all three channel types — Postgres Changes, Presence, and Broadcast — with production-ready examples. Type Use Case Data Source Postgres Changes React to INSERT/
Power BI is a powerful business analytics service developed by Microsoft that empowers users to visualise data and share interactive dashboards across their organisation. While Power BI can handle data from various sources, its true potential is unleashed when connected to robust data sources like SQL databases. SQL databases—such as PostgreSQL, MySQL, and SQL Server—are the industry standard for
If you've been building with Supabase, you know their Storage API is fantastic for web apps. But sometimes, you just need your files on your local machine—whether for a manual backup, bulk editing, or migrating data. While you could write a script using the Supabase SDK, there is a much faster, "no-code" way to manage your files like a Pro: Cyberduck. Note: Cyberduck is an official Supabase partne
Supabase Webhooks Deep Dive — Database Triggers, pg_net & Edge Function Patterns Supabase Webhooks let you react to INSERT/UPDATE/DELETE events on any table and call an external endpoint or an Edge Function automatically. Under the hood it uses the pg_net extension to fire non-blocking HTTP requests directly from PostgreSQL triggers. DB change → pg_net (async HTTP) → Edge Function or external en
The problem: too many clients, too few discovery hooks We expose Supabase Edge Functions as MCP (Model Context Protocol) servers. The clients that hit them are heterogeneous — Claude Desktop, Codex CLI, Cursor, VS Code Continue, a couple of in-house browser extensions. None of them ship with a hard-coded "use WorkOS AuthKit, scope is tool:ai_chat, audience must contain urn:jibun:tool:<tool>" rec
