## Database Sample

DatabaseSample tackles the blank-page problem in data modelling. Instead of opening an empty designer, you search a catalogue of 1,847 published database designs — each with an ER diagram, table and column details, and an automated review that flags missing keys, absent indexes and other structural problems. Nearly a thousand multi-table sample datasets are also available with intact foreign keys, shipping as CSV, JSON, SQL for four dialects, a Prisma seed or a Django fixture, all released under CC0 with no account required.

Around that library sits a working toolkit. The DBML text editor renders a diagram as you type, the SQL playground runs queries in PostgreSQL or SQLite directly in the browser and shows the query plan, and share links bundle the schema, query and result into one reproducible URL. Field generators produce valid UUIDs, localised names, non-uniform numbers and test card data, while SQL dialect converters translate DDL between MySQL, PostgreSQL and SQL Server and spell out the semantic differences.

The AI side is the AI Generator and Dataset Studio. Describe the dataset you need and the model proposes a schema; the Free plan lets you run three designs a day and download a 50-row sample of every table, while Pro and Team plans raise limits, unlock complete datasets and private downloads, and add a stronger model inside the editor. Team workspaces add roles, comments and review requests, and a GitHub Action can review pull requests that change a shared schema.

**Pricing & Plans:** Freemium. All published database designs and datasets are free to download with no account. Dataset Studio generation starts free (50-row samples, 3 designs/day); Pro is $19/month for complete datasets and 25 designs/day; Team is $15 per user per month ($45/month for 3 seats) with shared workspaces; Education is free for verified school email addresses. Yearly billing costs ten months' price; Team is 50% off for verified educators.

- **1,847 database design catalogue:** Browse ready-made schemas by subject, each with an ER diagram, full column details and an automated design review that calls out missing keys and indexes.
- **AI schema generator and Dataset Studio:** Describe the data you need in plain English, compare generated designs, and download generated rows with working foreign keys in CSV, JSON, SQL, Prisma or Django formats.
- **In-browser DBML editor and SQL playground:** Write schema as DBML text and watch the diagram update live, then query generated rows in PostgreSQL or SQLite, inspect the query plan and share the whole thing as one reproducible link.
- **997 multi-table sample datasets under CC0:** Deterministically generated datasets with valid foreign keys, available in eight download formats with no account, no attribution and no restrictions.
- **SQL dialect converters and field generators:** Translate DDL between MySQL, PostgreSQL and SQL Server with differences called out, and generate UUIDs, localised names, skewed numeric distributions and standard test card numbers column by column.

**Strengths:** The design catalogue, sample datasets and download formats are free with no account, making it easy to evaluate before paying anything; Sample data is genuinely relational — foreign keys stay intact across tables, so it loads and queries like real data; Tooling is unusually complete for one site: catalogue, editor, diagram, SQL playground, converters, generators and AI design in one place; Transparent, published pricing with a free education tier and yearly billing equal to ten months

**Limitations:** Generated Studio results expire after 30 days on every plan, including paid ones, so output must be downloaded to be kept; The free tier is deliberately narrow — 50-row samples, three AI designs a day and 20 editor AI requests per month; Credit-style daily limits mean large modelling sessions on the Free plan require waiting for the next day

## Schematic

Schematic is a monetization infrastructure platform aimed at SaaS and AI companies whose billing has outgrown a simple subscription. The premise is that in a usage-heavy AI market, pricing is no longer a static set of plans but a moving target: inference costs change, customers expect to be billed for what they consume, and sales wants to negotiate custom terms. Schematic answers this by modelling plans, credits, add-ons, trials and feature gates as configuration data on a real-time ledger, so changing a price is a config change rather than an engineering project.

Three capabilities run together in that engine. Metering ingests and counts every billable event exactly once; enforcement applies the resulting limits and entitlements inside your product in real time, scoped to a company, a user or an AI agent; and credits let you sell consumption as prepaid balance with burn rates, rollover rules, auto top-up policies and à la carte bundles. Because plans are versioned like code, teams can publish a new version, preview it for customers, migrate subscribers immediately or at period end or not at all, and keep legacy customers on the plans they signed up for. Custom terms — payment deadlines, grace periods, activation on payment or immediately — are handled as plan attributes rather than one-off invoices.

The customer-facing half is just as deliberate: wallet, usage and plan components are meant to run inside your own product, showing customers exactly what they have used, what they owe and what is left, with usage caps per user and per agent and audit trails for support conversations. The company markets itself to both product developers and commercial teams, and publishes case studies about AI features launched on credit-based billing in days rather than quarters.

**Pricing & Plans:** Schematic offers a free trial and self-serve account signup, with paid plans and enterprise agreements available. Pricing is quote-based depending on usage volume and requirements, so check the site or book a demo for current terms.

- **Real-time metering and enforcement:** Every billable event is counted once and every limit is applied in real time, by company, user or agent, so usage and access never drift apart.
- **Credits and prepaid wallets:** Sell usage as credits with configurable burn rates, rollover percentages, auto top-up thresholds and deadlines on promotional grants.
- **Catalog and plan versioning:** Define plans, add-ons, trials and feature gates as data, then version a change, preview how it looks to customers, and roll it out without deploying code.
- **Bring-your-own-pricing models:** Model seats, pay-as-you-go, tiered overage, pay-in-advance commitments, hard and soft limits, or hybrids in the same engine.
- **Auditable credit ledger:** Inspect every grant and decrement for finance and support, audit balances, grant promotional credits and reconcile the books.

**Strengths:** Treats pricing as versioned configuration, so commercial changes do not require engineering sprints; Unifies metering, entitlements and credits on one ledger instead of stitching tools together; Customer-facing wallet and usage components run inside your own product, not a separate portal; Explicit support for AI-era models: credits, agent-level usage caps, prepaid commitments and rollovers

**Limitations:** It is monetization infrastructure rather than an end-user product, so it requires genuine integration effort to see value; Teams already deep in a competing billing provider may find migration disruptive; Public pricing is not fully self-serve, so evaluation may require talking to sales
