## 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

## Open WebUI

Open WebUI is an open-source, self-hosted interface for working with AI models. Instead of renting access to a single vendor's chatbot, you run the interface on your own hardware or cloud tenancy, then connect whatever models you want: local runtimes such as Ollama, OpenAI-compatible endpoints, Anthropic, or a mix of local and remote. Everything a team produces — conversations, prompts, models, skills and tools — stays in an environment you administer.

The platform has grown well beyond a chat window. Retrieval-augmented generation, web search, document understanding, voice input and output, and vision are built in, and Python tools, functions and pipelines let developers script custom behaviour and share it. On the operations side it offers enterprise features such as SSO, role-based access control, audit logs, data residency options, and on-premises, hybrid or fully air-gapped deployment for regulated environments. White-labeling and custom branding are also available for organizations that want their own look.

Open WebUI is distributed free of charge under an open-source license and can be installed with a single pip or Docker command, with no account required to get running. A separate enterprise offering is available for organizations that want commercial support, compliance guarantees and managed rollout help, which is quoted on contact. A large community maintains a public hub of prompts, models, tools and functions, so much of what teams need is already shared and ready to install.

**Pricing & Plans:** The core platform is free and open source, installable via pip or Docker with no account required. An enterprise tier with support, compliance and deployment assistance is quoted on contact.

- **Any Model, Any Endpoint:** Connect local runtimes like Ollama alongside OpenAI-compatible and Anthropic APIs, and switch between them inside one interface.
- **Retrieval and Search Built In:** RAG over your own documents, web search and citation-aware answers come standard, so responses are grounded in real sources.
- **Python Tools, Functions and Pipelines:** Extend the platform with Python code to add custom tooling, preprocessing, and multi-step pipelines, then share them with others.
- **Enterprise Controls:** SSO, RBAC, audit logs, data residency, and on-premises, hybrid or air-gapped deployment for organisations with strict requirements.
- **Community Hub:** Browse and install prompts, models, skills and tools contributed by hundreds of thousands of community members.

**Strengths:** Free and open source with no account needed to install; Works with local and cloud models through a single interface; Strong privacy posture: your data and models stay on your infrastructure; Extensive enterprise features including SSO, RBAC and audit logs

**Limitations:** Self-hosting requires you to handle servers, updates and backups; Some enterprise capabilities and support sit behind a paid, quote-based tier; Feature depth means a learning curve for non-technical administrators; Local model performance depends heavily on your own hardware
