## Ardent

Ardent tackles a problem that shows up the moment coding agents start writing database code: there is no safe, fast place to test it. Seed files and hand-built fixtures drift from reality, so bugs only surface in production. Ardent instead clones your real Postgres database on demand, giving each agent or developer a complete, isolated copy to work against.

The clones are built to be both fast and cheap. Ardent reports clone loads of under six seconds regardless of database size, with copy-on-write storage so you only pay for the data that actually changes, plus compute that autoscales with agent workloads and scales to zero when idle. Isolation is enforced at both the compute and storage layer, so an experiment on a branch cannot affect the production instance.

Ardent plugs into infrastructure you already run, including Supabase, AWS RDS for Postgres, and PlanetScale, and adds Git-style collaboration so teams can branch, share, and promote database changes the way they already handle code. It is aimed squarely at AI-native teams running large fleets of agents, where conventional replication and manual resizing do not keep up.

**Pricing & Plans:** Ardent uses a freemium model: a free tier to get started, tiered paid plans as agent workloads grow, and custom/enterprise plans. The vendor asks interested teams to contact them or book a demo for tailored pricing.

- **Sub-6-second database clones:** Create a 1:1 copy of any Postgres database in under six seconds and keep that speed even at terabyte scale, so agents never wait on test environments.
- **Zero blast radius isolation:** Every branch is isolated at the compute and storage level, meaning experiments, migrations, and data cleaning can never reach or damage production.
- **Storage-efficient copy-on-write:** Clones only consume storage for the changes actually made, instead of duplicating the full dataset for every branch.
- **Compute that autoscales to zero:** Branch compute scales with agent workloads and drops to zero when idle, so you never pay to keep idle test databases running.
- **Works with your existing Postgres:** Branch against Supabase, AWS RDS Postgres, and PlanetScale with zero configuration changes, preserving extensions, auth, and provider-specific settings.

**Strengths:** Clone times stay under six seconds even at terabyte scale, removing test-environment bottlenecks; True compute and storage isolation keeps every experiment away from production; Copy-on-write storage plus scale-to-zero compute keeps branch costs low; Native support for Supabase, AWS RDS Postgres, and PlanetScale with zero config changes

**Limitations:** Focused on Postgres and the listed providers, so other database engines are not covered; Pricing requires contacting the vendor, which makes quick cost comparison harder; Enterprise customization means more setup than a pure self-serve tool

## 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
