B2B SaaS with SSO and SOC 2: what to build it with and what it costs

A multi-tenant product for companies: organisations, SAML single sign-on, audit logs and a SOC 2 report.

Sample PRD

Organisations and roles
SAML SSO
Audit logs
Per-seat billing
Data residency options

What it needs

Organisations / B2B teams: each customer company is a tenant
SAML / enterprise SSO: enterprise customers sign in through Okta or Entra ID
SOC 2 report available: security reviews ask for SOC 2
Subscriptions: per-seat plans
Postgres: tenant data with row-level isolation
Can run or store data in the EU (nice to have): EU customers want data in the EU

What drives the cost

SSO is usually priced per connection or on enterprise tiers
Compliance tooling and audits (not priced here)
Sign-in per active user as seats grow

Lock-in

SSO connections are configured by each customer; moving sign-in providers means every customer reconfigures.

Give your AI assistant

It plans the stack, prices it at your scale, and hands back package names, environment variables and docs. Your assistant writes the code.

Then keep going in the same chat. Pick up a saved project, price a change before it is built, track setup step by step, and ask why the bill went up.

I’m building a booking app for yoga studios with sign-in, payments and email reminders. What should it run on, and what will it cost at 20,000 users?

Example prompt. The answer is a live result from recommend_stack, the tool your assistant calls, at today’s prices.

No vendor pays to be listed or ranked higher, and there are no referral links.

Every price change is public: who changed what, when and why.

Already built?
Start from what you run.

Point it at your files, repository or website to see what to keep and what to change. Then bring in what you actually pay, next to what you estimated.

Sign-in required for billing and saved stacks.

Spend less time collecting bills

Import a CSV, upload a text-based PDF, paste an invoice or enter an amount. Recurring subscriptions add completed months automatically.

Supported OpenAI, Anthropic, Vercel, Stripe, AWS and DigitalOcean connections sync completed months nightly. Billing access depends on the provider; personal Claude API keys cannot read organization costs.

Forward receipts when they arrive

When receipt forwarding is enabled, send receipts to your private billing address and review the service, month and amount in Billing. It reads the email body, not attachments; upload PDFs separately.

Revisit decisions when things change

Save a stack or audit and enable alerts for price changes, approaching cost jumps, expiring credits and bills above estimates. Checks run daily using saved usage assumptions and require a confirmed email.

Audit Your Stack

Already built? See what your app runs on, what it costs now and as you grow, what it's missing, and what to change.

What's it built on?

Drop files or a project folder package.json, requirements.txt, .env.example, vercel.json, fly.toml, Dockerfile… Only names of services are read; nothing is kept. Choose Files

Or paste a package.json, .env.example or a list of services

Your audit appears here: a grade, what to change first, and what each service costs as you grow.

Plan your stack for free.

Every tool, on this website and in your AI app, is free while Kong Reviews is in preview. There's nothing to buy.

Questions

What is Kong Reviews?

It scopes what you build next, a new product or a feature for the app you already have: which services to use (hosting, database, sign-in, email, payments, analytics and more), how to set them up, and what they will cost now, as you grow and after startup credits. Use it on this website with a free account, or from your AI assistant over MCP each time you plan a feature.

Where do the prices come from?

From each vendor's own pricing page. 70 of the 70 vendors in the cost engine were checked against their pricing pages in October 2026; any others are marked unverified. The other services on Vendors were read in October 2026 for their free tier and lowest paid price; the ones we couldn't read are marked Not Priced Yet. Both keep growing: we add vendors and services as we research them. Every answer lists its sources and the date each price was checked, and a price counts as out of date after 14 days. Check the vendor's page before you commit to anything.

Is it really free?

Yes. Every tool is free during the preview, within fair rate limits. There are no paid plans yet.

Do I need an account?

Yes, a free one, to plan or audit on this website. It also keeps your stacks and sends price alerts. Create it with your email address (we send a 6-digit code, no password) or with GitHub, which asks for no permissions beyond your public profile.

How do I use it from Claude or ChatGPT?

Open Connect AI and pick your app for the setup steps. Then ask in plain language, for example "Here's my PRD, what should I use?"

Do vendors pay to be listed or ranked higher?

No. Rankings come only from fit and cost, and there are no affiliate or referral links. See How we make money.

What happens to the PRD I paste?

It is read on our server with keyword rules to find requirements, then discarded. It is not stored and not sent to an AI provider. See Privacy.

How do I delete my data?

Sign in and go to Settings → Account → Delete account. That removes your account, your saved stacks and every sign-in straight away.

Can you add a vendor?

Yes, and we'll look at adding it.
