## Give AI agents **all** your data. Plug Claude, ChatGPT + Gemini into every system you run - SaaS, IT, OT, IoT, files - anything. Get AI agents that can finally see _all_ your business. # Comparing Leading Low Code Platforms: OutSystems, Mendix, Appian, Retool, Rayven, Bubble & Glide Paul Berkovic, 10 July 2025 ## Core capabilities & development model. - **Rayven:** Full-stack [low-code platform](/content/site-root.html) with rich integration and AI. Rayven provides a hybrid prompt-to-build, drag-and-drop app builder, plus full access to code. It couples 200+ ready connectors (SaaS, APIs, databases, IoT protocols) with data protocol connectors and the ability to code integrations; delivering universal interoperability which can be coupled with its visual workflows to orchestrate data and logic in real-time. UIs are built via drag-drop widgets (50+ pre-built widgets) with HTML/JS injection for custom design. Rayven also embeds ML/GenAI toolkits and supports hybrid SQL/Cassandra databases, making it more flexible than pure no-code tools. It can handle anything from forms and dashboards to complex real-time data flows; blending UI, workflows, DataOps, and AI in one platform. It's pricing structure means lone developers and enterprises can benefit from its features. - **OutSystems:** Enterprise-grade low code with full-stack focus. OutSystems is a professional low code IDE for web/mobile and core systems. It provides model-driven UI and business logic design, plus full access to code for custom needs. Key strengths include built‑in DevOps and DevSecOps automation. For example, OutSystems advertises “full-stack development” handling complex logic and data with ease, and AI-assisted app generation. OutSystems apps compile to standard .NET or Java code, letting teams inject custom code or integrate legacy systems. - **Mendix:** Visual model-driven platform (now part of Siemens). Mendix uses a domain model and “microflows” to define logic. Developers use Mendix Studio (web-based) or Studio Pro (desktop) to build UI and process logic visually, with optional Java/JavaScript extensions. Mendix supports collaborative development and has built-in Agile/DevOps. Like OutSystems, Mendix targets complex business apps and supports advanced customisation (e.g. you can plug in your own Java actions). - **Appian:** Process-centric low-code. Appian combines low code with business process management (BPM). It provides a drag-drop designer for process flows, rules, forms and reports. Developers build reusable process models, UI, and integrations. Appian has pre-built "Smart Services" (AI, RPA, document processing), but also lets developers code expressions or APIs. Its emphasis is on end-to-end process automation. - **Retool:** Developer-oriented internal tools builder. Retool is a JS/React-centric low code IDE for building internal web apps and dashboards. You drag UI components (tables, charts, forms) and bind them to data via queries or JavaScript. Retool is very code-friendly: you can write SQL/JS anywhere and even embed custom React components. It comes with connectors to databases and APIs out of the box. - **Bubble:** No-code web app builder. Bubble uses a fully visual, drag-drop editor for responsive web apps. Business logic and data workflows are defined with visual rules. Bubble manages hosting and scaling of apps on its AWS-based cloud. It has a plugin ecosystem and API connector for integrations. - **Glide:** Mobile-first no-code app platform. Glide turns spreadsheets into apps. It provides a visual UI builder (mobile/web interfaces), workflows and some basic logic, all driven off data in Google Sheets, Excel, Airtable or Glide’s own tables. ## Scalability & enterprise-readiness. - **OutSystems:** Designed for horizontal scaling. OutSystems runs on containers/microservices. Apps can be deployed anywhere – OutSystems Cloud, AWS, Azure or on-prem – and can scale to millions of users. - **Mendix:** Cloud-native and multi-cloud. Mendix is built to run on Kubernetes or classic servers. - **Appian:** Enterprise-grade PaaS. Appian can be run as a SaaS cloud (Appian Cloud) or on-premises. - **Retool:** SaaS or self-host. Retool’s default is SaaS (hosted on AWS), with an option for self-hosted deployment for extra security. - **Bubble:** Hosted cloud only. Bubble apps run on Bubble’s managed servers (AWS). - **Glide:** Multi-tenant mobile PaaS. Glide hosts your apps on its cloud. - **Rayven:** Designed for high-scalability. Rayven’s stack is cloud-native and IoT-capable. ## Security, compliance & data governance. - **OutSystems:** Strong enterprise security with add-ons. - **Mendix:** Enterprise-grade controls. - **Appian:** Security-first platform. - **Retool:** Solid baseline security. - **Bubble:** Moderate security. - **Glide:** Good for business apps. - **Rayven:** Enterprise-grade by design. ## Pricing models. - **Rayven:** Usage-based tiers. - **OutSystems:** Custom enterprise licensing. - **Mendix:** Tiered subscription per app. - **Appian:** App-and-user licensing. - **Retool:** Transparent seat pricing. - **Bubble:** Flat monthly plans. - **Glide:** User- and usage-based. ## Low Code Platforms Comparison Table. | Platform | Core Dev Model & Features | Scalability / Deployment | Security / Compliance | Pricing Model | Extensibility / Ecosystem | | --- | --- | --- | --- | --- | --- | | **Rayven** | Drag-drop UI, workflows, data ops, ML/AI toolkits. | Cloud-native multi-cloud or on-prem. | Enterprise-grade security. | Free tier; then $50, $500, $1000 per month plans. | 200+ built-in connectors. | | **OutSystems** | Full-stack enterprise low code. | Cloud-native: Docker/k8s | ISO 27001 certified | Quote-based licenses | Forge component marketplace.| | **Mendix** | Model-driven low code. | Cloud-native (Kubernetes). | Enterprise features. | Freemium: Free plan (2,500 WU). | Mendix Marketplace. | | **Appian** | Process-centric low code. | Scales on multi-node clusters. | FedRAMP, SOC2, ISO27001 certified. | Named-user pricing | Appian AppMarket (pre-built apps). | | **Retool** | Drag-drop internal tool builder. | SaaS or self-host. | ISO 27001 & SOC2 compliant. | Free for 5 devs (limited). | Built-in DB connectors . | | **Bubble** | 100% visual web app builder. | Bubble-managed AWS hosting. | TLS/SSL by default. | Four tiered plans (plus Enterprise). | Huge plugin marketplace. | | **Glide** | Spreadsheet-driven mobile/web apps. | Hosted on Google Cloud. | Uses Google infrastructure security. | Free Explorer plan for personal use. | Supports Google Sheets, Airtable, Excel. | ## Ecosystem & extensibility. - **Rayven:** Hybrid integration/IaaP approach. - **OutSystems:** Extensive marketplace and IDE extensibility. - **Mendix:** Full app stores. - **Appian:** Appian uses an AppMarket. - **Retool:** Extensible through React and APIs. - **Bubble:** Massive plugin marketplace. - **Glide:** Built-in components only. ## Support, training & community. - **Rayven:** Offers 24/7 email/phone support on higher plans. - **OutSystems:** Very mature support. - **Mendix:** Strong learning platform. - **Appian:** Enterprise support and training. - **Retool:** Developer-focused docs. - **Bubble:** Strong no-code community. - **Glide:** Good documentation and responsive support.
