## Base44

Base44 is a no-code AI platform built around "vibe coding": you describe what you want in plain language, and the platform generates the app's structure, interface, logic, and backend for you. Rather than producing a static mockup, it delivers a running application complete with database, authentication, integrations, and one-click hosting — so the gap between prototype and something you can actually use in front of customers is very small.

Beyond building, Base44 covers the operational side. Superagents are AI agents that connect to your tools, manage data, and automate recurring workflows while you are offline. A built-in SEO/GEO dashboard helps you get discovered on search engines and AI assistants, and the platform can draft ready-to-post social content based on what you built. Analytics and design controls let you keep the whole product on brand and measurable after launch.

Base44 is designed for founders validating an idea, internal teams building tools and dashboards without engineering capacity, and small businesses that need a website or store live quickly. Start with a free plan that includes monthly credits and all core features; paid tiers begin at $16 per month billed annually and add more credits, unlimited apps, code edits, and custom domains, with enterprise options available on request.

**Pricing & Plans:** Free plan with monthly credits and core features; paid plans from about $16/month billed annually with more credits, unlimited apps, code edits, and custom domains; enterprise pricing on request.

- **Full-stack app generation:** Describe an idea and get a working app with database, authentication, payments, and hosting already wired up — no server or infrastructure setup.
- **AI website builder:** Generates complete websites with layout, copy, and design, plus built-in SEO tools and custom domain support, ready to publish in one click.
- **Superagents and custom agents:** Create 24/7 AI agents that connect to your tools, take real actions, manage data, and automate recurring workflows autonomously.
- **Built-in integrations:** Connects to Google Calendar, Gmail, Slack, Notion, HubSpot, Salesforce, and more, with API access for anything else you use.
- **Growth and design tooling:** SEO/GEO dashboard, app analytics, AI-generated social content, and centralized color and font controls for consistent branding.

**Strengths:** Generates truly full-stack apps, not just static designs; Backend, auth, payments, and hosting are included with no setup; Free tier with monthly credits makes it easy to evaluate; Strong ecosystem of integrations plus API access for anything else

**Limitations:** Credit consumption on every AI generation can add up during heavy iteration; Complex, highly custom logic may still need manual code edits or engineering support; Advanced team and security capabilities sit behind higher-priced tiers

## Cosine

Cosine started as an AI software engineer aimed at understanding and working across entire codebases, and has since grown into a sovereign-AI company serving organisations that cannot send sensitive data to third-party frontier models. The product line now centres on the Lumen model family, including Lumen Sovereign—a frontier model trained on the UK's Isambard-AI supercomputer with UK Government backing—alongside Lumen Outpost and Lumen Scout variants for different deployment postures.

Alongside the models, Cosine ships three agent surfaces. Cosine CLI delegates complex engineering tasks to agents that reason across full codebases, write and refactor software, run tests and work autonomously in an existing development environment. Cosine Desktop brings autonomous assistance into everyday desktop workflows for research, document and spreadsheet analysis and coordination across local files and tools. Cosine Cloud assigns long-running work to isolated environments, runs tasks in parallel and lets teams review results together with built-in controls for usage, model access and spend.

Security and sovereignty are the organising principles. Deployments can be fully air-gapped inside a customer's own infrastructure with no external connectivity, run in a dedicated managed single-tenant environment, or accessed through Cosine's managed public cloud. Organisations can also post-train an open-weight model, adapt Lumen Sovereign to their own domain knowledge, or commission an entirely new foundation model built to their requirements.

**Pricing & Plans:** Cosine offers a free trial entry point and a public cloud tier; enterprise, single-tenant and air-gapped deployments are quoted individually. Check the pricing page or contact the team for current figures.

- **Lumen Sovereign frontier models:** A family of frontier LLMs trained on the UK's Isambard-AI supercomputer and specialised for UK and EU regulatory frameworks, legacy programming languages and mission-critical workflows, with 1T and 200B parameter variants announced.
- **Three deployment models:** Run Cosine fully air-gapped inside your own infrastructure, in a dedicated managed single-tenant environment, or through Cosine's managed public cloud—with data handling and access controls set by you.
- **Cosine CLI, Desktop and Cloud:** Agent surfaces that cover terminal-driven engineering tasks, everyday desktop research and document work, and long-running parallel jobs in isolated cloud environments.
- **Air-gapped and defence-grade use:** Designed for defence, government and critical national infrastructure teams that need frontier reasoning inside disconnected networks.
- **Custom and post-trained models:** Adapt Lumen Sovereign to your organisation's specialist knowledge, post-train an existing open-weight model for your tasks, or work with Cosine to build a purpose-built foundation model from scratch.

**Strengths:** Deployment flexibility spanning public cloud, managed single-tenant and fully air-gapped setups; Model line purpose-built for regulated industries rather than adapted from a general-purpose assistant; Strong sovereign and data-residency story, including UK Government backing for Lumen Sovereign; Covers both day-to-day coding agents and long-running autonomous cloud tasks

**Limitations:** Enterprise and sovereign deployments are quote-based, so pricing transparency is limited; Sovereign model availability has announced timelines rather than immediate general availability; Air-gapped and custom-model projects typically require significant internal infrastructure and lead time
