## 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

## 21X (formerly Structurely)

21X, previously known as Structurely, is a conversational AI platform for automating the conversations that drive revenue and customer experience. It covers inbound and outbound voice, two-way SMS, RCS, email and chat from a single agent builder, so a mortgage lender, real estate team or home services company can qualify leads, answer routine questions and keep every follow-up moving without expanding a call centre.

The platform is organised around a four-step flow: connect the tooling that captures inbound calls and maximises outbound contact rates; converse with fine-tuned AI that sells, overcomes objections, follows up and handles requests; take action by booking appointments, scheduling callbacks, transferring calls and extracting insights; and sync everything back by dispositioning conversations and updating your CRM automatically. Because actions and dispositions flow into existing systems, AI-handled conversations appear in the same pipelines your team already reports on.

Commercial terms combine a platform fee with usage-based metering in tokens, so cost scales with actual activity rather than idle seat licences. Voice usage runs as low as $0.07 per minute with your own carrier (BYOC), SMS as low as $0.02 per message and AI email as low as $0.02 per email. Three tiers are offered — Small Team, Large Team and Enterprise/Build Your Own — with the top tier adding custom SLAs, isolated infrastructure, SSO/SAML, white-label or headless deployment and dedicated AI engineering support. The company is headquartered in Aspen, Colorado.

**Pricing & Plans:** Platform fee plus usage-based pricing. No seat licences; you pay for the platform and for activity metered in tokens. Voice from about $0.07 per minute (BYOC), SMS from about $0.02 per message, AI email from about $0.02 per email, with volume discounts on higher tiers. Three plans — Small Team, Large Team and Enterprise / Build Your Own — are quoted via sales; a demo AI call is offered before you commit.

- **Inbound and outbound AI voice:** AI agents handle inbound calls and run proactive outbound campaigns across voice, SMS, email and chat, 24/7, without adding headcount.
- **Multi-channel conversation routing:** Agents qualify, answer, transfer, schedule, escalate and route each conversation based on intent, context and your business rules.
- **Action taking, not just talking:** Book appointments, schedule callbacks, execute live transfers to human reps, trigger workflows and capture documents and signatures automatically.
- **Automatic dispositions and CRM sync:** Conversations are dispositioned automatically, CRM records are updated, and customer data syncs back into your existing tools and workflows.
- **AI Power Dialer for Salesforce:** Launch AI and human dialing campaigns directly from Salesforce with call screening, live transfers and performance reporting.
- **Agent builder with industry templates:** Build agents with prebuilt industry templates for mortgage, real estate, life insurance, home services, private aviation and more.

**Strengths:** Handles voice, SMS, RCS, email and chat in one platform rather than separate point tools; Automatic dispositions and CRM sync keep AI conversations inside existing reporting; No per-seat licensing; cost tracks actual conversation volume; Prebuilt industry agents for mortgage, real estate, insurance, home services and more

**Limitations:** Platform fee is not published, so you must talk to sales to model total cost; Usage is metered in tokens, making spend harder to forecast than flat per-seat pricing; Initial setup of agents, telephony, A2P registration and workflows requires onboarding effort; Advanced capabilities like SSO/SAML, dedicated infrastructure and white labeling are Enterprise-only
