What stacks do you scale?

Vercel, Cloudflare, Supabase, Postgres, Next.js, TanStack Start, Lovable, Bubble, Node, Python, Go. If it's modern web or serverless, we've scaled it.

How realistic is your load testing?

We profile your real traffic patterns first, then simulate them with k6 or Artillery — not generic 'hit the homepage 10k times' tests.

Can you do this before a Product Hunt / press launch?

Yes — Launch Harden is built for exactly that. Two to three weeks is enough to pre-fight the spike for most stacks.

What if I'm already on fire right now?

Pre-Flight as an emergency triage often works in 48 hours. We stabilize first, then plan the full pass.

Will you babysit my launch day live?

Full SRE Pass and Scale Watch include a live on-call window. Lower tiers include async response and a runbook.

Do you handle cost overruns from autoscaling?

Yes — every Launch Harden tier and above sets budget caps and per-service spend alerts so you don't get a surprise five-figure invoice.

How does payment work?

Fixed-price tiers split 50/50. Scale Watch is monthly, cancel anytime with 14 days notice.

Yes. Your infra, your monitoring, your dashboards, your runbook. We document and hand off cleanly.

// BEFORE

Single-region. No queue. No cap.

Synchronous AI calls in the request path. DB on the cheapest tier. No alerts until users complain.

// AFTER

Edge cache, queues, autoscaled, observed.

Slow work is async. Pool sized for the spike. Hard cost caps. Runbook in Slack. Boring launch.

// MISSION.BRIEFING

The SRE squad founders can rent for one launch.

Scale Hero is a focused performance & resilience pass that load-tests your stack under realistic launch-day traffic, identifies every bottleneck, and hardens each one — caching, queues, connection pools, autoscaling, observability.

One operator. One stress test. One stack that survives going viral.

// MISSION.CAPABILITIES

What we harden before your moment arrives.

📈

Realistic Load Testing

k6 / Artillery scenarios that mirror your actual user paths — not synthetic traffic that lies.

⚡

Caching Layers

Edge cache, CDN, application cache, database query cache — each tuned where it actually moves the needle.

🗄️

Database Hardening

Connection pooling, read replicas, query plan fixes, hot-row protection — the stuff that fails first under load.

🧵

Queues & Backpressure

Move slow work off the request path. Add backpressure so spikes degrade gracefully instead of taking everything down.

👁️

Observability

Real metrics, traces, error tracking, alerts. You'll know about issues before users tweet about them.

💰

Cost Ceilings

Autoscale limits, budget alerts, per-route cost tracking — so a viral spike doesn't end with a five-figure invoice.

// DISTRESS.SIGNALS

You need Scale Hero if…

You've never load-tested past 50 concurrent users

And your launch plans include 'hopefully a lot of people show up.' Hope is not a capacity plan.

Your DB plan is the cheapest tier

Connection limits, IO caps, and burst credits will be the first thing to hit a wall.

You have no error monitoring

Sentry, Datadog, or even basic Logflare — if 5% of requests are failing, you can't see it.

There's no autoscaling and no autoscale cap

Either you stay small or you wake up to a surprise invoice. There's no middle ground.

Critical work runs inside the request

Email sends, AI calls, image processing — all happen synchronously. One slow dependency takes everything down.

Your runbook is in your head

If something breaks at 11pm on launch day and you're asleep, nobody knows what to restart, scale, or roll back.

// WHY.THIS.HAPPENS

Most modern stacks scale to 100 users without trying — and fall over at 1,000.

Serverless, edge, autoscaling — modern infra makes the first 100 concurrent users feel effortless. That same architecture has cliffs at 1k, 10k, and 100k that founders never see until they hit them.

Launch traffic is bursty, weird, and unforgiving. Press hits send thousands of curious visitors who bounce in 8 seconds. Viral TikToks send teenagers who hammer search and never convert. Both will find the slowest endpoint in your stack and stay there.

Scale Hero pre-fights these fights. We simulate the burst, fix the bottleneck, and stand up the observability so launch day is something you can actually enjoy instead of survive.

Boring launches are the best launches. We make yours boring.
