Stack for SaaS founders
The Indie SaaS Stack for SaaS Founders
A 7-tool stack for SaaS founders whose product launched but whose dashboard is flat. Hosting, payments, transactional email, analytics, project tracking, marketing site, and the social proof layer.
Verified · editorial policy
TL;DR
As of , the short version is: SaaS founders who ship the product but skip the marketing stack hit the post-launch wall: trial signups that don't activate, a marketing site that looks like the dashboard, and zero attribution. The 7-tool indie stack puts the operational backbone (Vercel, Stripe, Resend) under a category-leading marketing surface (Framer, Senja) with measurement (Plausible) and execution tracking (Linear).

Why this shape of stack
SaaS founders typically over-engineer the product and under-build the funnel. This stack inverts the bias: the operational layer is fast and boring (Vercel, Stripe, Resend), the marketing layer is opinionated and high-design (Framer, Senja), and the loop closes through analytics (Plausible) and execution tracking (Linear).
The stack, in funnel order
Vercel(Frontend cloud and hosting)
Application and marketing site hosting
Vercel's deploy-on-push + preview-URL-per-branch flow turns the marketing site into a iteratable surface, not a quarterly redesign project. Edge runtime + ISR + image optimization are operational defaults, not premium features.
Swap notes: Render or Railway if you need long-running workers; Vercel for the frontend either way.
Stripe(Payments infrastructure)
Subscription billing and revenue infrastructure
Stripe Billing handles trials, dunning, proration, and SCA out of the box. The Customer Portal removes the cancel-flow friction that protects retention but kills NPS. For B2B SaaS, Stripe Invoicing covers wire-transfer customers without re-platforming.
Swap notes: Lemon Squeezy or Polar if you want MoR tax handling and don't need raw Stripe APIs.
Resend(Email API)
Transactional email (signup, password reset, billing)
Resend's React Email integration + clean API removes the SendGrid bloat without losing deliverability. Critical for SaaS where the welcome email and the password reset are the first product surfaces a user sees post-signup.
Swap notes: Postmark is the closest direct alternative; SendGrid if you're on legacy infra.
Plausible Analytics(Privacy analytics)
Privacy-first product and marketing analytics
Most pre-revenue SaaS doesn't need full PostHog yet. Plausible's funnel view + goal tracking covers conversion-from-marketing-site through signup, and the privacy-first model removes the GDPR overhead.
Swap notes: Fathom is the direct alternative; PostHog or Mixpanel if you need product analytics depth.
Linear(Project management for software teams)
Engineering execution and bug tracking
Linear's keyboard-first speed and Cycles model fit indie teams better than Jira or Asana. The GitHub integration closes the loop between issue tracking and code review without context-switching to a project management tool.
Swap notes: ClickUp or Asana if you have a non-engineering team that lives in tasks.
Framer(Design and prototyping)
Marketing site and launch surface
SaaS marketing sites need to look like the product team takes design seriously. Framer hits that bar without a designer hire, and the CMS handles the changelog + case study + pricing comparison pages without re-platforming.
Swap notes: Webflow, Carrd, or a Next.js site if you already own the design system.
Senja(Testimonial collection)
Customer testimonial and case study collection
Pre-revenue SaaS needs the first ten testimonials more than the first ten features. Senja's collection widgets ship into Slack, Intercom, or the in-app activation moment, and the import flow handles Twitter screenshots + LinkedIn quotes alongside structured collection.
Swap notes: Testimonial.to is the direct alternative.
What to build first
Vercel + Stripe + Resend before anything else. These three are the operational backbone – the marketing site, the billing flow, the auth/signup emails all depend on them. Skip the marketing-side tools until the first paid signup verifies the funnel hypothesis.
The mistake this cohort most often makes with stack-building
Picking analytics tools that produce more dashboards than decisions. Pre-revenue SaaS rarely needs PostHog – it needs to know whether the marketing-site CTA gets clicked and whether trial signups activate. Plausible answers both, in one screen.
Questions SaaS founders ask
Do I need PostHog or Mixpanel from day one?
No. Below ~100 active trial users per month, full product analytics produces noise, not signal. Plausible covers conversion-from-marketing-site through signup; instrument PostHog or Mixpanel when activation/retention becomes the bottleneck.
Should I run my SaaS on Edge / Fluid Compute or Node.js Lambda?
Fluid Compute (Vercel's default) for most cases – it handles long-running tasks (300s default timeout) and reuses warm instances. Edge for auth checks and lightweight transforms only. The choice doesn't usually matter pre-revenue – pick what your framework defaults to.
What about CRM or sales tools?
Pre-revenue SaaS doesn't need a CRM. Notion or Linear plus a shared inbox handles the first 50 conversations. Add HubSpot or Pipedrive when the sales motion crosses 10+ active opportunities monthly.
Should I use Stripe direct or a Merchant of Record like Lemon Squeezy?
Depends on geography. Stripe direct if your customers are mostly US-based or you have an accountant handling VAT/sales tax. Lemon Squeezy or Polar if you sell globally and want VAT/EU compliance bundled. The MoR fee is usually worth it for a solo founder selling outside North America.
