Pre-launch unit cost + pricing audits

You built it.
Now what should you charge?

Point PrePrice at your project. In a couple of minutes you get a clear verdict: what it costs to run, what to charge for it, and which parts of your code are quietly eating your margin. Cut today's bill. Ship something that stays cheap as it scales.

Why this exists
“I accidentally burned ~$0 of Claude usage overnight with one command.”

That is the actual title of a real Reddit post. A developer left one /loop command running unattended on Opus 4.7. 46 iterations later, 26 hours later, ~$6,000 gone before the invoice email even arrived. u/procrastinator_eng on r/ClaudeAI, Apr 2026. Bills like this happen because nobody runs the math before they ship. PrePrice runs it for you in a couple of minutes, so the next surprise bill is the one you saw coming.

Built for founders who don't want their app to be a money pit.

We track pricing across 100+ services so you don't have to read every vendor's page.

The problem you didn't build a spreadsheet for

From 20 pricing tabs to one clear verdict.

Every service in your stack has its own pricing page. Free tier, paid tier, usage tier. Per-request, per-seat, per-event, per-gigabyte. Some meter bandwidth. Some meter active rows. Some charge for the seat and then again for the run. The same number on two vendor pages can mean two completely different things.

Working out what your specific build will actually cost means opening 20 tabs, reading the fine print on each one, and stitching it together yourself. Most builders do not bother. They guess, ship, and find out in the invoice.

We do the math for you. Three questions your audit will answer:

01

Are you profitable at $9.99?

Most vibe-coded apps are not. The gap is usually wider than founders expect.

02

Where's the spend going?

Most of it is one or two lines of code you forgot to cache, or a retry loop that tripled your bill.

03

Does this scale to 10k users?

You scaled to that number in your head. Whether your stack did is a different question.

What a PrePrice scan actually looks like.

80 seconds, end to end. Drop in a repo, watch the verdict, the stack, the cost projection, and the file-by-file fixes come back.

How it works

Finally, a pricing tool you don't need to be an engineer to use.

Connect your project and walk away with the math. It would otherwise take a week of spreadsheets and pricing pages to assemble it yourself.

01Scan anything

Drop in your project. We read it.

GitHub link or zip upload. SaaS app, agent, agentic flow, weekend side project. It does not matter what you built. We pull out the cost-relevant parts and skip the rest. We never run your code. Your source is wiped seconds after we read it, never written to our database, never embedded, never copied. Every report ships with a cryptographic receipt so you can verify exactly that.

preprice.app/scan/yourproject/report
The scan submission wizard: a GitHub repo URL field with two tabs (Paste a GitHub link / Upload a folder), a 'What you'll get back' card listing verdict, cost per user, expensive bits, and pricing recommendation. Run my scan button at the bottom.
preprice.app/scan/yourproject/report
Detected stack section showing five services across four categories with $808.50/mo total: Vercel Pro $640, Redis $168.50, Postgres (free), Next Auth (free), OpenTelemetry (free). Each row has a verified-pricing badge and external link to the vendor's pricing page.
02Find hidden costs

See every vendor, priced for what you're actually doing.

Our catalog covers 100+ services: Vercel, Supabase, Stripe, Anthropic, OpenAI, ElevenLabs, Pinecone, and 90 more. For each one we map what your code actually uses, show you the live tier, and link back to the vendor's page so you can verify every number.

03Project your costs

Project your costs at any scale.

The slider sweeps from 100 users to a million, and every service in your stack reacts in real time. Verified vendors use their real multi-dimensional pricing (bandwidth, storage, requests), so you see exactly where each tier ladder bites.

preprice.app/scan/yourproject/report
Findings & fixes view showing 5 issues with a $4,490/month at 10k users headline savings. The first finding is 'Uncached System Prompt in Main Chat Loop' at app/(chat)/api/chat/route.ts:232, marked High confidence, with a ~$630/mo savings tag, a what's-wrong block, and a how-to-fix block.
04Fix the leaks

Find the parts of your app that are quietly wasting money.

For every cost driver we surface: file path, line number, what's wrong, the fix, and what it saves you at 1k and 10k users. Copy the whole list as a single prompt and paste it straight into Cursor or Claude Code. We do the diagnosis. You keep the credit.

Your code is yours

Your code is never saved. We wipe it from our servers in seconds after producing a report.

PrePrice was designed so your source code never lives anywhere we control for longer than it takes to read it. The numbers below describe what actually happens, not aspirational policy.

Wiped in seconds, not hours

GitHub: we shallow-clone into an ephemeral worker disk that gets rmtree'd the moment your scan finishes, success or failure. Zip uploads:the object is deleted from our storage the second we finish unzipping it. Both timestamps appear on every report's receipt.

Never written to our database

Your source bytes never reach Postgres. Only the structured audit (cost drivers, vendor links, fix recommendations) is persisted. Enforced by an RLS policy named in the receipt. There is no row in any table that contains your code.

Cryptographic receipt

Each report ships with a SHA-256 of the exact archive (or repo HEAD commit) we analyzed. Re-hash your local copy with shasum -a 256 or git rev-parse HEAD and confirm we analyzed what you sent. No third-party audit needed.

Secrets stay on your machine

Before any analysis runs we delete every .env, credentials file, SSH key, and auth token from the worker disk. We detect your stack from package.json, imports, and hosting config instead. The receipt lists exactly what was scrubbed.

Audited pricing

We track and scrape pricing across 100+ products.

Every number in your audit comes from a real plan on a real vendor page. Parallel AI agents scrape each pricing page and cross-check the results, an automated quality pass validates every number against the source, and a human reviewer reads the diff and signs off before the row enters the engine. Each entry is stamped with a verification date so you can see how fresh the number is. The catalog spans LLMs, hosting, payments, voice, vector databases, auth, monitoring, and analytics, with every plan and pricing dimension modeled, not just a single sticker price.
