Access-control audit tool for no-code client portals

What to build

A permissions-audit tool for AI app builders (Bubble, Retool, Softr, FlutterFlow) that automatically scans multi-tenant client portals for row-level and record-level access leaks — like direct record URLs bypassing filtered list views — and ships as an automated test suite plus a permission-matrix template, aimed at agencies and solo devs building per-client B2B portals.

No-code/low-code app builders don't guarantee tenant isolation out of the box, so agencies shipping client-facing portals with mixed staff/admin/client roles have no reliable way to verify that one client can't see another's records.

Demand

Agencies and freelancers building multi-tenant client portals on Bubble, Retool, Softr, or FlutterFlow want assurance that permissions actually hold before go-live — a concrete current example is a firm setting up a portal for around 40 clients asking exactly this question.

  Thread titled 'What's the best AI app builder with permissions that hold up for our client's data?' — poster describes setting up a portal for around 40 clients and needing permissions that hold up.

• Signal aggregator (internal)Signal

  Signal flagged as a tech-category opportunity, global region, with no historical match and a moderate novelty/confidence score of 0.56.

• Opportunity framing (internal analysis)Analysis

  Identifies direct record URLs bypassing filtered list views as a concrete attack surface for multi-tenant data leaks in client portals built on Bubble, Retool, Softr, and FlutterFlow.

Stack

• Playwright (automated URL/record access fuzzing)
• Bubble Data API
• Retool REST API
• Softr API
• Supabase (store scan results and permission matrices)

Solo + AI difficulty

The core idea — a script that logs in as different roles and tries to hit other tenants' record URLs/API endpoints directly — is easy to prototype for one platform in days with AI help. The hard part is building reliable per-platform auth handling and generalizing across Bubble, Retool, Softr, and FlutterFlow, each with different data/API models; a realistic MVP scoped to one platform (e.g. Bubble) plus a manual permission-matrix template is achievable in 2-4 weeks.

Entry threshold

Buildable by a solo developer in a few weeks as a wrapper or checklist-and-scanner tool on top of existing no-code platforms, requiring no licences, though it demands real expertise in access-control edge cases to be credible.

Window

6-12 months

Where to find first users

• r/nocode and r/Bubble
• Retool, Bubble, FlutterFlow, and Softr community Slack/Discord groups
• Indie Hackers
• No-code agency directories and freelancer communities (e.g. Bubble agency partner lists)

Counter-signals & risks

• The query may reflect a single user's due-diligence question rather than a widespread or recurring pain point, and the score of 0.56 with no historical match suggests weak corroborating signal strength.

• Established platforms like Retool already market built-in role-based access control and audit features, which could reduce perceived need for a third-party permissions-testing tool.

• Agencies and solo developers may be too price-sensitive or small-scale to pay for a dedicated audit product, favoring manual QA checklists or built-in platform features instead.
