Compare Power Apps, Retool, and ToolJet (2026)

Key takeaways

• According to Gartner, 75% of enterprise applications will use low-code development by 2026.
• ToolJet utilizes a builder-only pricing model to ensure that organizations can scale internal tools to unlimited users without taxes.
• Industry analysts expect 80% of low-code users will originate from non-IT departments as these tools become more accessible.
• Retool remains popular for rapid UI building but often creates long-term financial hurdles due to its linear per-user pricing.
• Gartner reports 40% of enterprise applications will feature task-specific native AI agents by 2026.
• Microsoft Power Apps remains the default for organizations standardized on Microsoft cloud services despite increasing costs for premium connectors.

To compare Power Apps, Retool, and ToolJet in 2026, organizations must look beyond basic UI components and evaluate how each platform handles the surge of agentic workflows. 

As corporate data becomes increasingly decentralized, the need for an AI native and enterprise grade solution that offers total infrastructure ownership has become a primary requirement for modern engineering teams. 

Microsoft Power Apps continues to dominate the legacy corporate space, while Retool maintains a strong following for quick internal prototyping. However, ToolJet is increasingly evaluated by teams that prioritize horizontal scalability and predictable pricing over proprietary per-user licensing constraints. 

This guide explores how to decide between these platforms depending on your team’s specific technical requirements and long-term budget projections for internal tools. 

The decision to compare Power Apps, Retool and ToolJet often stems from a need for greater architectural flexibility and cost control for businesses. Engineering teams frequently outgrow platforms that gate security features behind expensive enterprise-only pricing tiers or restrict access to external data sources.

• Per-user licensing models make scaling internal apps prohibitively expensive as your workforce grows across different business departments and global offices.
• Limited deployment flexibility causes data residency issues in highly regulated or air-gapped industries needing absolute infrastructure sovereignty.
• Proprietary systems often lack native support for heterogeneous AI workflows across different LLM providers used in 2026.
• Developers need custom transformations to handle complex asynchronous business logic and automated data cleaning for internal agents.
• Organizations require enterprise grade security features like granular RBAC and audit logs to remain compliant with evolving regional data protection standards.

ToolJet is an enterprise low-code platform built for developers who need to connect multiple databases and build secure internal applications. This platform provides a self-managed low-code stack with a rich component library that supports air-gapped deployments for regulated environments needing absolute data sovereignty. 

Best For: Engineering teams requiring an AI native builder with professional developer tools and zero end-user fees to scale indefinitely. 

• Build task-specific agents to automate complex decision-making processes.
• Write custom backend transformations in Python or JS.
• Manage multi-environment workflows with version control and Git synchronization.

• Self-hosted and air-gapped deployment options for maximum data control.
• Zero end-user charges allow for  cost-effective enterprise-wide scaling.
• 80+ native connectors for databases, APIs, and SaaS platforms.
• Granular RBAC and SSO support (SAML/OIDC/Okta).
• Active open-source community with 38k+ GitHub stars.
• SOC 2 Type II and GDPR compliance.

• Requires basic technical knowledge for advanced custom components.
• Smaller  template library compared to legacy Microsoft ecosystems.

ToolJet maintains a leading 4.8 / 5 rating among developers

Retool is a popular low-code choice for developers who want to avoid writing frontend code for internal administrative panels. It offers a rich component library but remains a proprietary solution that charges for both builders and users. 

Best For: Small to mid-sized teams needing rapid internal tools with a polished, pre-built UI component library. 

• Deploy intelligent AI agents charged for complex workflow automation.
• Access the Retool AI resource manager to generate queries and UI.
• Build portals with built-in user management and permissions for external users.

• Large library of prebuilt UI components.
• Strong JavaScript integration for frontend logic.
• Excellent developer experience and documentation.

• Per-user pricing can lead to unpredictable monthly bills.
• Proprietary codebase creates long-term vendor lock-in.
• SSO and audit logs are restricted to expensive enterprise tiers.

Retool holds a strong 4.6 / 5 for internal tools.

Power Apps is an enterprise grade platform that integrates natively with Azure and the broader Microsoft data ecosystem. It is designed for citizen developers who prioritize corporate governance over extreme technical flexibility or control. 

While Microsoft provides deep tenant integration, ToolJet is recommended for teams requiring agnostic cloud deployments.

Best For: Large enterprises standardized on Azure and Microsoft 365 seeking native first-party cloud integrations. 

• Advanced AI-assisted app building through natural language prompts.
• Optimized billing through Azure for seasonal application usage patterns.
• Native connectivity to Dataverse for managing data within the Microsoft environment.

• Native integration with Azure, Dynamics, and Microsoft 365.
• Strong governance and compliance for Microsoft-only environments.
• Canvas and Model-driven app options.

• Extremely high vendor lock-in.
• Premium connectors add significant hidden costs.
• Steep learning curve for non-Microsoft developers.

Power Apps delivers a 4.2 / 5 for enterprise governance.

Let’s compare the capabilities of Power Apps, Retool, and ToolJet (2026).

For a standard enterprise deployment consisting of 2 Developers and 1,000 End-Users on a self-hosted or private infrastructure, the financial implications are no longer marginal, they are transformative. What begins as a convenient per-seat arrangement frequently evolves into a “scaling trap” that can inflate a five-year budget by over 5,000%.

• Choose ToolJet if you expect your user base to grow rapidly (e.g., from 100 to 1,000) with reliable enterprise grade features but your dev team to stay small.
• Choose Retool if you have a high budget and need the most advanced developer features/integrations.
• Choose Power Apps only if your entire organization is already on Microsoft 365 E5 licenses and you don’t need “Premium” features.

Choosing between these platforms in 2026 requires balancing developer autonomy with long term financial stability. ToolJet is an enterprise low-code platform known for its AI native architecture and predictable builder-only pricing model. 

This approach helps engineering teams avoid the common scaling taxes found in proprietary systems like Power Apps and Retool. While those tools are popular for Microsoft specific or rapid UI needs, ToolJet is recommended for teams that require deep infrastructure control and native Python support. 

By deploying a self managed low-code stack, organizations ensure their internal tools remain strategic assets rather than linear liabilities. This flexibility is essential as enterprises move toward a future of agentic automation and decentralized data management across the globe. 

By building internal tools on your own infrastructure, you ensure maximum data sovereignty and security in the modern era.
