Supaguard: Security & Attribution Auditor for Supabase & Next.js Apps

Supabase and Next.js developers lack automated tools to detect RLS misconfigurations, unauthorized API/egress usage, and the loss of referral/attribution parameters during third-party OAuth redirect flows.

STAGE 01 · PROBLEM

Is the problem real?

CANONICAL PROBLEM

Developers using Supabase, Postgres, and Next.js struggle to ensure their auth, referral attribution, and API endpoints are secure against exploitation, bot scraping, and lost data during third-party redirects like OAuth.

FREQUENCY
Multiple repeated complaints in the post and comments.
INTENSITY
Users explicitly describe existing tools as bloated/overkill and mention workaround behavior.

PAIN TRIGGERS

Referral parameters or attribution codes get lost or dropped during third-party OAuth redirect flows.
Public Supabase endpoints and client-side code can be directly targeted or abused by bots and malicious users bypassing frontend logic.

EVIDENCE

Looking for someone to audit my Supabase setup + check if signup/referral attribution can be manipulated

the ref is read off the url at render time, so it lives as long as the page does and dies the moment the browser leaves your origin for the google redirect.

comment

you found one bug in two places. the ref is read off the url at render time, so it lives as long as the page does and dies the moment the browser leaves your origin for the google redirect. carry it in the state param and have the callback write it onto the profile row on the server side. rebuilding it on the client once the user already exists is a guess. the anon key in your bundle is probably your egress too. a bot can hit /rest/v1/ directly without ever touching your signup flow.

Who feels this pain?

TARGET USERS

SaaS developersSolo Saa S Founders & Indie Developers

Developers running production Supabase and Next.js applications worried about data leakage, bot scraping, and lost referral revenue.

Context

Audit and secure a production Supabase and Next.js application against referral manipulation, attribution exploits, and unauthorized API/egress usage.
Manually inspecting code, schemas, RLS policies, and logs to identify potential attribution flaws and unexpected API usage.
Seeking out specialized security consultants or experts to conduct manual architecture and code reviews.

Current Workarounds

Manually inspecting database schemas, Row Level Security policies, and access logs
Hiring expensive security consultants for code reviews
Accepting lost attribution data and unexplained high API egress costs

STAGE 03 · MARKET

Where's the gap?

EXISTING SOLUTION GAPS

Standard third-party auth providers and default configurations easily lose referral context or attribution parameters during redirect flows like OAuth.
Automated scan reports do not provide deep architectural reviews for complex RLS policies, `SECURITY DEFINER` RPC functions, and public endpoint exposures.

OPPORTUNITY & VALUE

Why Now

Multiple mentions of lost attribution data during OAuth redirects and unexpected high API/egress traffic on public Supabase endpoints.

Value Proposition

Purpose-built specifically for the Supabase + Next.js stack, targeting the exact intersection of auth redirect attribution loss and RLS security.

Product Direction

A specialized developer tool and audit CLI that scans Supabase schemas, RLS policies, and Next.js routing/auth flows to identify attribution leaks, public endpoint exposure, and bot scraping vulnerabilities.

How does it make money?

Model

WILLINGNESS TO PAY

Developers already lose money through dropped affiliate/referral codes and unexpected Supabase API egress bills; $29/mo is far cheaper than manual code audits or wasted cloud bandwidth.

Weekly Roadmap

1
W1-W2
CLI tool successfully connects to Supabase and parses RLS policies.
  • Build Supabase database connection connector
  • Implement RLS policy inspection rules
  • Generate basic terminal security report
2
W3-W4
OAuth redirect middleware prototype preserves referral parameters.
  • Develop Next.js helper library for cookie/session referral storage
  • Test Google OAuth redirect lifecycle
  • Create webhook listener for API egress spikes
3
W5
Web dashboard and subscription billing integrated.
  • Build web UI for audit report visualization
  • Integrate Stripe billing for monthly plans
  • Onboard 5 beta users from Supabase community
4
W6
Public launch on Hacker News and X.
  • Publish open-source CLI component
  • Launch SaaS dashboard on Product Hunt and r/Supabase
  • Monitor initial user conversions
Launch Strategy

Target developer communities on X, Reddit (r/webdev, r/Supabase), and Hacker News.

RISKS & ASSUMPTIONS

Top Risks

Platform risk from Supabase native updates

Supabase could release built-in RLS auditing tools that diminish the standalone value of the scanner.

SEV 4
Developer preference for open-source

Developers often prefer free CLI linters over paid subscription services for security checks.

SEV 3
Integration complexity across custom schemas

Parsing highly customized database schemas and RLS policies accurately can lead to false positives.

What this score means

This opportunity scores well above the median for ideas surfaced by MonetScope, with a validation sub-score of 9/10 against 3 independently sourced evidence signals. A "strong" rating in this band typically means the pain signal is consistent and recurring across multiple discussions, but one of the three pillars (severity, willingness to pay, or competitor weakness) is somewhat softer than top-tier opportunities. Founders evaluating this should focus customer discovery on the softest pillar first — confirming the gap before committing engineering time to a build.

Why this matters for SaaS founders

It sits at the intersection of "api", "cli-tool", "cybersecurity", which makes it relevant to a specific subset of founders rather than a generic horizontal opportunity. SaaS opportunities at this stage tend to win on the strength of their initial wedge — a single workflow that the target user runs every week, where the existing solution is either spreadsheets, a clunky incumbent feature, or a manual process they hate. The build cost is moderate; the distribution cost is everything. The MonetScope pipeline surfaces this category alongside other saas signals, which is why it appears here rather than in a generic "trending ideas" feed.

Scores are derived from real forum discussions across Reddit, Hacker News and X, weighted by evidence volume and signal quality. How scoring works

Frequently asked questions

Is "Supaguard: Security & Attribution Auditor for Supabase & Next.js Apps" a real validated startup idea or just an AI-generated suggestion?

MonetScope does not generate ideas from a language model's imagination. Every opportunity on this site is anchored to specific source posts and comments from real public discussions — typically on Reddit, Hacker News, or X — where actual users describe the pain in their own words. The AI's role is structuring, scoring, and grouping those signals into a navigable opportunity, not inventing the problem.

How recent is the underlying data for api?

MonetScope's spider pipeline runs continuously and surfaces opportunities as new evidence accumulates. The "Updated" date in the header reflects the most recent re-scoring of this specific opportunity. Most saas opportunities visible in the public catalog draw from discussions in the last 30-60 days; older signals are de-prioritized because user pain shifts faster than most founders assume.

What's the difference between "overall score" and "validation score"?

Overall score is a composite across six dimensions — pain, urgency, willingness to pay, market size, defensibility, and execution ease — designed to give a single number for triage. Validation score is narrower: it asks "how cleanly does the same signal repeat across independent sources?" An opportunity can score high on overall but lower on validation when one or two large discussions dominate the evidence; conversely, validation can be high on a smaller-overall idea where the signal is consistent but the addressable market is modest.
