## Cradle

Cradle is a protein engineering platform that applies machine learning to the design and optimization of proteins. Instead of optimizing one property at a time, teams use Cradle to work on potency, specificity, expression, thermostability, and manufacturability simultaneously — compressing the number of experimental rounds needed to reach a candidate that meets a target profile.

The platform covers a broad range of protein classes, including antibodies for ADC and multispecific formats, enzymes that need to hold up in hostile conditions, vaccine antigens that must keep their shape outside the lab, and peptides that need potency within tight constraints even from small datasets. It works whether or not a starting protein already exists, and it learns from the customer's own experimental data, including results from previous failed campaigns, so each design round is better informed than the last.

Cradle is positioned for multiple roles in an organization: experimental scientists get point-and-click candidate design and optimization; computational scientists get the same functionality exposed through an API for scripting and integration; and R&D leadership gains a compounding advantage from every experiment their teams have run. Security is a stated priority, with ISO 27001 and SOC 2 Type II certification and hosting on Google Cloud. Pricing is not published — interested teams discuss their project with Cradle to get terms.

**Pricing & Plans:** Pricing is not publicly listed. Cradle uses a contact-for-pricing model where teams discuss their project and program scope directly with the company; a licensing track and API access are offered alongside the core platform.

- **De novo protein design:** Start from a target or your own sequence and have Cradle design an optimized plate of candidates informed by your data and domain knowledge.
- **Parallel multi-property optimization:** Improve efficacy, developability, and manufacturability in parallel rather than one property at a time, compressing time to a target profile.
- **Closed-loop learning from experimental data:** Every round incorporates results from the previous one, so experimental data compounds across campaigns and prior failed programs stay useful.
- **Full API access:** Everything in the web application is exposed through the API, so computational teams can script campaigns and wire Cradle into existing pipelines.
- **Enterprise-grade security and compliance:** ISO 27001 and SOC 2 Type II certified, hosted on Google Cloud with data isolation and continuous monitoring for enterprise deployments.

**Strengths:** Optimizes multiple protein properties in parallel rather than sequentially, which can cut the number of experimental rounds; Learns from a customer's own experimental data, including negative and failed results; Covers antibodies, enzymes, vaccines, and peptides in one platform; Full API parity with the web app supports computational and automated workflows

**Limitations:** No self-serve trial or published pricing, so evaluation requires a sales conversation; Requires in-house experimental capability to generate the assay data that drives the models; Cost and onboarding are geared to organizations rather than individual researchers

## 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
