Searchers look for mastra supabase when they want one stack: TypeScript agents plus Postgres they already trust. This is the integration map I use on client work.
Why the pair works
- Mastra gives agents, workflows, eval hooks, and a dev playground in TS
- Supabase gives Postgres, auth, RLS, and realtime without running another database vendor
Most Joburg and Cape Town SaaS teams I work with already have Supabase. Adding Mastra avoids a second memory product.
Architecture sketch
- Auth: Supabase session on the Next.js app; agent routes require logged-in user
- Memory:
agent_threadsandagent_messagestables withuser_idFK - RLS: policies so users only read their own thread rows
- Tools: server-side functions that call Paystack, CRM, or internal APIs (never expose service role to the browser)
- Deploy: Vercel for Next + Mastra handlers; Supabase hosted or self-managed
Minimal table ideas
-- Illustrative only: adapt to your schema
create table agent_threads (
id uuid primary key default gen_random_uuid(),
user_id uuid references auth.users not null,
title text,
created_at timestamptz default now()
);
alter table agent_threads enable row level security;
create policy "own threads" on agent_threads
for all using (auth.uid() = user_id);
Store tool results you need for audit, not every token stream.
Pitfalls in SA projects
- Putting Paystack secrets in client-side tool definitions
- Skipping idempotency on webhook tools the agent can trigger
- No rate limits on public agent endpoints (expensive abuse during load shedding news spikes)
