Which Lovable Skills should a SaaS install first?

Start with Supabase Auth Pro, Stripe Subscriptions, and Resend Transactional. Those three cover sign-up, billing, and notifications — the minimum to run a paid product.

Do I need separate Skills for trials and subscriptions?

No — Stripe Subscriptions handles trials, plans, upgrades and the customer portal in a single Skill.

Is there a Skill for GDPR compliance?

Yes. The GDPR Baseline Skill adds a cookie banner, DSAR endpoint and data-export flow. Combine it with Audit Log for sensitive-action history.

Lovable Skills for SaaS: The Curated Stack

A curated stack of Skills for B2B and B2C SaaS teams. Auth, billing, transactional email, analytics, compliance, retention — all the boring-but-critical surface, ready to install.

Why a curated stack?

Every SaaS ends up rebuilding the same five things. This stack collapses that work into installs, so your team's time goes into the product, not into wiring webhooks for the fifth time this year. If you want the universal top-of-charts list instead, see Top 10 Lovable Skills of 2026; the picks below are filtered specifically for SaaS shape.

Auth & user management

Supabase Auth Pro — Email + Google + RLS done correctly.
Magic Link Onboarding — Passwordless sign-in with branded emails.
Team Workspaces — Orgs, members, invites, roles.

Billing & monetization

Stripe Checkout — Hosted checkout + webhooks.
Stripe Subscriptions — Plans, trials, customer portal.
Usage Metering — Track and bill metered usage.

Comms & retention

Resend Transactional — React Email + Resend.
In-app Notifications — Realtime feed with read state.
Weekly Digest — Personalized recap emails.

Analytics & growth

PostHog Analytics — Identified events + funnels.
SEO Audit — Audit and ship the fixes.
A/B Experiments — Feature flags + experiments.

Trust & compliance

GDPR Baseline — Cookie banner, DSAR endpoint, data export.
Audit Log — Append-only log of sensitive actions.
Rate Limiter — Per-IP and per-user limits, Redis-free.

Suggested install order

Auth → so everything else can scope to a user.
Billing → so you can charge before you scale support.
Transactional email → so signups, receipts and resets work day one.
Analytics → so you can tell which features actually matter.
Compliance → before you need it, not after the first complaint.

Pairing Skills with Knowledge

Skills carry the procedure; project Knowledge carries the policy. For SaaS specifically, capture: pricing tiers, currency, tax handling, the personas you sell to, your support SLA, and the words you don't use in the product. The combination is what produces a coherent experience instead of a Frankenstein of installed features. We unpack this in detail in Skills vs Knowledge.

Stack archetypes

Solo founder MVP — Stripe Checkout, Supabase Auth Pro, Resend Transactional, PostHog Analytics. Ship in a weekend, charge by Monday.

B2B with teams — add Team Workspaces, Audit Log, and SSO-ready auth. Sales motion needs receipts and access control more than it needs novelty.

Usage-based product — Stripe Subscriptions plus Usage Metering, with PostHog wired into the same identifier. Bill what you measure; measure what you bill.

EU-first SaaS — GDPR Baseline first, then billing with VAT-aware invoices via the PDF Invoice Skill listed in the top 10.

Don't install yet

Realtime everything. Add presence and live updates when a real customer asks, not preemptively.
Heavy admin dashboards. A read-only Supabase view beats a half-built admin panel for the first six months.
Custom analytics. The PostHog Skill covers 95% of what early SaaS actually queries.
