- Open-source foundation allows teams to self-host and extend the platform
- Built-in row-level security and policies simplify permission management
- Relatively new and may lack enterprise-grade SLAs
- Less flexibility if your data model requires a non-relational store
- Scaling large clusters may require manual tuning and careful indexing
- Some advanced analytics and caching capabilities are limited, requiring external services
Gitlab
Best for: Micro development teams who need comprehensive DevOps capabilities without enterprise-level complexity.
- Unified interface for Git repos, CI/CD pipelines, issue tracking, and container registry
- Auto DevOps detects project type and configures pipelines
- Built-in security scanning and compliance tools
- Built-in package and container registry keeps artifacts close to code and enforces access control
- Value stream analytics and pipeline dashboards show cycle times and highlight bottlenecks
- Fine-grained permissions and group-level management
- Self-hosted and SaaS options are available
- The feature set can overwhelm teams that only need basic source control or CI/CD
- Auto DevOps may require customization to fit edge-case workflows
- Self-managed installations demand resources for maintenance, upgrades, and high availability
- Some advanced features require higher-tier plans, increasing costs
- Performance can be affected without careful runner and database tuning
Criteria for evaluating Postman alternatives
When evaluating Postman alternatives, focusing on key factors will determine the tool's effectiveness for your team. The most critical evaluation criteria can be weighted as follows.
Core functionality
Effective API platforms enable users to construct, send, and test API requests with support for REST, GraphQL, and gRPC protocols. Look for features like dynamic variables, environment management, automated test scripting, and assertion capabilities that maintain API quality. Tools that simplify mocking, documentation generation, and version control streamline the API lifecycle from design through deployment.
User experience and support
Intuitive interfaces and smooth onboarding reduce friction for development teams and API consumers. Access to comprehensive documentation, tutorials, and active user communities helps resolve challenges quickly. Platforms offering real-time collaboration, role-based access, and workspace management enhance teamwork and reduce version conflicts.
Integration capabilities
Native integrations with source control systems, CI/CD pipelines, monitoring tools, and communication platforms improve workflow automation and feedback loops. API access and webhook support facilitate custom extensions and seamless syncing with existing developer tools. Deep integration reduces manual handoffs and enables continuous testing and deployment.
Value for money
Pricing models vary by user counts, API call limits, mock server availability, and collaboration features. Consider free tier limits and costs of scaling with team size and usage. Transparent pricing aligned with expected API traffic and feature needs helps avoid unexpected expenses and ensures cost-effective growth.
Industry-specific requirements
Certain sectors demand enhanced security, governance, and compliance features such as SSO, audit trails, and encryption. Platforms providing specialized templates or integrations for regulated environments (healthcare, finance) better support these needs. Consideration of specific workflow requirements ensures alignment with organizational standards.
How to choose the right alternative
You can use the following approach when selecting the best-suited tool for your team.
Assess your team's requirements

- Map integration points with existing DevOps tools
Test drive before committing
- Use trial versions to build and test sample APIs
- Collaborate with team members on shared projects
- Evaluate documentation generation and mocking capabilities
- Collect user feedback on usability and support
Evaluate long-term fit
- Review vendor update schedules and roadmap transparency
- Assess platform scalability for growing API traffic
- Plan for integration with emerging tools and frameworks
- Consider vendor stability and community activity
Consider support and training resources
