The SaaS Founder Stack
Backend, billing, automation, session replay, and event data — everything a small SaaS needs before it needs a team.
You are building and shipping a product. You need infrastructure that scales past the prototype without hiring a platform engineer to run it.

Why These 5 Tools Work Together
Buy anything that is not your product. Auth, billing, and session replay are solved problems and building them is how a six-week launch becomes six months.
Keep operational logic out of the application. Trial reminders and Slack alerts belong in an automation tool where changing them costs a deploy of zero.
Instrument before you launch. Retrofitting analytics onto a live product is the tax nobody budgets for.
The combined workflow: Build on Supabase with Claude as your pair, bill through Stripe, capture behaviour with Segment, watch actual sessions in LogRocket when something looks wrong, and run every operational alert and lifecycle email through Make or Zapier.
Who This Stack Is For
Early SaaS is a race between shipping speed and the accumulation of things that break. The stack you pick in month one decides how much of month six you spend on maintenance instead of features. Claude Pro is the pair programmer — better than any competitor at reading a whole codebase and explaining why a thing broke, which for a solo founder is the difference between a two-hour bug and a two-day one. Supabase gives you Postgres, auth, storage, and realtime behind one dashboard, so you skip the four weeks most founders lose building login and file uploads. Stripe is not really optional; the question is only whether you use Billing for subscriptions or roll your own, and you should not roll your own. Make or Zapier handles the operational glue — trial-ending alerts, onboarding emails, Slack notifications for new signups — without those becoming application code you have to maintain. LogRocket shows you the session where the user rage-clicked and left, which is more useful than any funnel chart. Segment keeps event definitions consistent as you add tools. Around $250/mo, most of it usage-based and cheap while you are small.
How the Stack Fits Together
- 1. BuildClaude Pro + Supabase
Postgres, auth, and storage wired up in days, not weeks.
- 2. ChargeStripe
Subscriptions, trials, and dunning handled.
- 3. MeasureSegment
One event schema across product and marketing tools.
- 4. DiagnoseLogRocket
The exact session where the user gave up.
- 5. OperateMake / Zapier
Trial alerts, onboarding emails, and Slack pings without code.
Your Stack, Tool by Tool
A breakdown of each tool, what it does in this stack, and how to get started.
Claude Pro
Pair Programming
Reads large codebases, explains unfamiliar errors, and writes migrations you can actually review. The most useful $20 a solo technical founder spends.
Key feature: Long context means it holds your schema, the failing file, and the stack trace at once.
In this stack: Works over your repo and Supabase schema; pairs well with Cursor as the editor.
Supabase
Backend & Auth
Hosted Postgres with auth, storage, realtime, and edge functions. Row-level security means multi-tenancy without a custom permissions layer.
Key feature: Real Postgres — you can leave without rewriting your data model.
In this stack: Webhooks into Make or Zapier; Stripe customer IDs stored against user rows.
Stripe
Billing
Subscriptions, metered usage, trials, tax, and dunning. Stripe Billing removes an entire category of edge cases you would otherwise discover in production.
Key feature: Customer portal — plan changes and card updates without you building a settings page.
In this stack: Webhooks drive Supabase entitlements and Make automations.
Make (or Zapier)
Ops Automation
Every lifecycle email, Slack alert, and internal notification lives here instead of in your codebase. Make is cheaper at volume; Zapier has more connectors.
Key feature: Visual scenarios with error handling and retries on failed operations.
In this stack: Triggered by Stripe and Supabase webhooks; posts to Slack and your email tool.
LogRocket
Session Replay & Monitoring
Watch the session, see the console errors and network calls alongside it. Turns 'it does not work' support tickets into a reproducible bug in minutes.
Key feature: Replay plus error tracking in one tool, tied to the affected user.
In this stack: Identifies users with Segment traits so replays are searchable by account.
Segment
Event Layer
Instrument once, route everywhere. Adding a fifth analytics tool later becomes a toggle instead of another SDK in your bundle.
Key feature: Free tier covers 1,000 monthly tracked users — plenty pre-traction.
In this stack: Feeds LogRocket identity, your analytics, and lifecycle email triggers.

- 1
Supabase
Model your schema and turn on row-level security before writing the first API route, not after.
- 2
Stripe
Use Billing and the hosted customer portal. Do not build plan management yourself.
- 3
Segment
Instrument signup, activation, and the two core product actions. Ship with those four events live.
- 4
Make
Trial ending, payment failed, and new signup alerts. Three scenarios cover most early ops.
- 5
LogRocket
Install before launch and identify users with the same IDs Segment sends.
- 6
Claude Pro
Keep a project holding your schema and architecture notes so debugging starts with context.
Swap-In Alternatives
Nothing here is sacred. If one tool does not fit how you work, these are the substitutions we would make.
Bonus Tools Worth Adding
