## 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

## Nelly

Nelly is built around the idea that a small team of specialised agents beats one general assistant. Inside Nelly Studio you describe what an agent should do using headings, lists and plain sentences - no code and no special syntax. You attach toolkits such as a browser or a database so agents can actually act, then test and refine their behaviour conversationally until they match your intent. Complex goals can be broken down into tasks delegated to sub-agents, effectively building a coordinated team.

Nelly Chat is where those agents go to work. You hold natural, contextual conversations with them in organised threads, group agents into departments with drag-and-drop, and inspect an activity view that shows which tools were used, browser screenshots and each step of progress. On the technical side, agents and their data run locally on your machine while the reasoning model runs in the cloud; Nelly says it transmits only conversation history and context to the LLM provider and does not store it.

Paid subscribers can connect their own model providers, including Anthropic, OpenAI, OpenRouter and LM Studio, for more control and privacy. Nelly currently uses Anthropic's Claude Sonnet 4 as its default model, supports Windows, macOS and Linux, and has an MCP server integration and a marketplace for sharing and monetising agents marked as coming soon.

**Pricing & Plans:** Nelly offers a free tier to start and paid subscription plans that unlock features such as connecting your own LLM providers. Pricing details are published on the site's pricing page.

- **Studio natural-language agent builder:** Create custom agents by describing their job in plain language with headings and lists; no coding or special syntax required.
- **Toolkits and sub-agents:** Give agents browser and database tools, and split complex work into specialised sub-agents to form a coordinated team.
- **Nelly Chat with threads and departments:** Hold natural conversations in organised threads, group agents into departments by drag-and-drop, and review detailed activity logs with browser screenshots.
- **Local-first data with cloud LLMs:** Agents and their data stay on your computer while only conversation context is sent to the model provider and not stored by Nelly.
- **Bring your own model provider:** Paid plans connect Anthropic, OpenAI, OpenRouter and LM Studio models for extra control and privacy, with MCP server support coming soon.

**Strengths:** Genuinely no-code: agents are defined in plain natural language; Local-first storage of agents and data with optional bring-your-own LLM provider; Supports browser and database toolkits plus sub-agent delegation; Available on Windows, macOS and Linux

**Limitations:** Marketplace and MCP server integrations are still marked as coming soon; Custom LLM providers require a paid subscription; Running agents locally means you manage the desktop app on your own machine
