Forum verdict · build Pain point

Drop-in middleware proxy for n8n that streams and paginates large Supabase result sets automatically, with a visual query planner that warns before a workflow will timeout

n8n's no-code promise breaks at scale and every power user hits this wall; solving it invisibly is the kind of infrastructure wedge that becomes a dependency

Built for n8n + Supabase users building analytics dashboards or reporting tools who need to query large datasets and render them in dynamic HTML without performance degradation or 502 errors.

The angle

Ships as a self-hosted Docker sidecar so it requires zero changes to existing n8n or Supabase setup, removing the biggest friction for adoption

Why this is a gap

Surfaced from a high-intensity complaint with clear willingness to pay and a specific, reachable audience.

The market

n8n and Supabase users building analytics dashboards hit 502 errors when querying 80k+ rows. No search volume, but the signal is a specific, high-friction technical pain in a niche automation + database stack.

Some rivals · 5/10 vs n8n built-in pagination (native node feature)PostgREST (Supabase's own HTTP layer with Range headers and cursor pagination)Windmill (open-source, handles large data with code steps and explicit pagination logic)Pipedream (managed workflow platform with built-in chunked execution and timeout controls)Hasura (GraphQL engine over Postgres with streaming subscriptions and query cost limits)pgBouncer / Supabase connection pooling (addresses the timeout/large-result-set root cause directly)

n8n and Supabase are the only real players here; most users either query smaller datasets or use native Supabase pagination. The gap is a purpose-built pagination layer that handles large result sets without gateway timeouts in n8n workflows.

What's hard to build

Building pagination logic that survives n8n's execution timeout constraints, manages Supabase's rate limits, and renders large HTML blocks dynamically requires deep knowledge of both platforms' internals and careful memory/concurrency tuning.

Why now

n8n lacks native large-dataset handling and users are hitting 502s; low-code automation platforms need better data-layer abstractions.
