## What it is

API platform for designing, testing, and documenting APIs. G2: 4.6/5 stars but growing complaints about bloat. Developers frustrated with forced login, performance degradation, and resource consumption. Once lightweight, now considered bloated by many developers who are switching to alternatives like Bruno, Insomnia, and Hoppscotch.

## Common problems

- **App extremely slow and unresponsive - takes 14+ seconds to start** (performance): Postman startup times have ballooned to 14+ seconds. The app becomes sluggish after running for a while, requiring restarts. Developers report the native application is extremely slow or unresponsive, especially after updates. One user measured 399MB disk space usage for what should be a simple HTTP client.
- **Memory hog - CPU constantly spiking at 50-60%** (performance): Postman consumes excessive system resources. CPU fans constantly spinning, CPU usage spiking to 50-60% while barely doing anything. Memory consumption grows over time, especially with large workspaces or long-running sessions. Multiple GitHub issues report this problem persisting across versions.
- **Forced login requirement - can't use without account** (usability): Postman v10 removed offline mode entirely. Users MUST create an account and login to use the app. You cannot save requests to collections without signing in. This is especially problematic for developers in corporate environments where external account creation is restricted.
- **Collections and data lost after update** (reliability): Users report losing all their collections, variables, and environments after refusing to create an account or after updates. Data cannot be recovered even after later creating an account. Critical workflow data lost permanently.
- **Privacy concerns - API data synced to cloud by default** (security): Logging in means API requests and data are synced to Postman's cloud servers. This raises significant privacy concerns for developers handling sensitive data, client APIs, or proprietary information. Many companies prohibit cloud sync for security reasons.
- **Bloated with features most developers don't need** (usability): What started as a simple REST client has become bloated with API documentation, mock servers, monitoring, and collaboration features. Developers who just want to test APIs must navigate through unnecessary complexity. The constant push toward web app and new features makes it feel overwhelming.
- **Freezes and crashes with large collections** (performance): Postman doesn't work well with large collections or on lower-end machines. The app freezes randomly or crashes completely. Users with hundreds of API endpoints experience significant lag when navigating or searching collections.
- **Free plan severely limited - only 1 user from March 2026** (pricing): Postman's March 2026 pricing update limits the free plan to just 1 user. Previous free teams must upgrade or lose collaboration features. The constant addition of paid add-ons makes pricing confusing, with costs escalating quickly for teams.
- **Sync issues in team workspaces cause data conflicts** (reliability): Team collaboration features have sync issues causing data conflicts, duplicate collections, and lost changes. Managing team permissions, collection versioning, and API definition updates becomes complicated with larger teams. Changes sometimes don't sync properly between team members.
- **No proper offline mode - requires constant internet** (usability): Many features depend on an active internet connection. The lack of fully functional offline mode is restrictive in low-connectivity environments or air-gapped development setups. Enterprise developers in secure environments can't use Postman at all.
- **Steep learning curve for advanced scripting** (usability): Pre-request and test scripts have a steep learning curve. Error messages are unclear, making debugging difficult. New users struggle with advanced features like environments, dynamic variables, and test assertions. Documentation exists but practical application is challenging.
- **Billing issues and refund requests ignored** (support): Trustpilot reviews cite poor customer service on billing issues. Postman is inflexible about refunding mistakenly added seats. Cancellation requests through the website don't complete and must be manually processed, with some requests remaining unprocessed for weeks.
- **No native database connections for testing** (integrations): Postman doesn't support direct connections to databases like MongoDB, PostgreSQL, or CosmosDB. Users must export data manually for testing, adding extra steps to workflows. Competitors offer better database integration capabilities.

## What users like

- **Comprehensive API testing and documentation platform**: Postman provides a complete suite for API development - designing, testing, documenting, and monitoring APIs in one place. The all-in-one approach eliminates switching between multiple tools for teams that need the full feature set.
- **Intuitive interface for basic API testing**: For simple API testing, Postman's interface is straightforward. Sending requests, viewing responses, and managing basic collections is easy to learn. Most developers can start testing APIs within minutes.
- **Wide range of authentication protocol support**: Postman supports OAuth 1.0, OAuth 2.0, API keys, Bearer tokens, AWS Signature, and more. Built-in auth handling saves time compared to manually constructing headers. Auto-refresh for OAuth tokens is particularly useful.
- **Strong collaboration features for teams**: Shared workspaces, team libraries, and collection sharing make collaboration easier for API teams. Version history, comments, and role-based access control support enterprise workflows when sync works properly.
- **Extensive CI/CD integration capabilities**: Newman CLI runner enables Postman collections in CI/CD pipelines. Integration with Jenkins, GitHub Actions, and other CI tools allows automated API testing. Collection runs can generate reports for test results.
- **Industry standard with large community**: Postman is the most widely used API platform, meaning extensive documentation, tutorials, and community support exist. Most API documentation includes Postman collection import buttons. Job listings often specifically mention Postman experience.

## Pricing

- **Free**: $0 (free) — hidden costs: Single user only from March 2026, No team features, Limited API calls for monitors and mock servers
- **Basic**: $14 (monthly) — hidden costs: Billed annually for discount, Monitor and mock server usage adds up, Add-ons required for advanced features
- **Professional**: $29 (monthly) — hidden costs: Significant cost increase from Basic, Still no SSO (Enterprise only), Usage-based overages possible
- **Enterprise**: $49 (monthly) — hidden costs: Requires annual commitment, Minimum seat requirements likely, Custom pricing for large deployments

## Who should and shouldn't use it

- **Developers who value privacy and local-first tools** — Avoid: Postman requires account creation and syncs data to cloud by default. Developers handling sensitive APIs or working in privacy-conscious environments should use Bruno or Thunder Client which store everything locally.
- **Developers on resource-constrained machines** — Avoid: Postman's Electron-based app consumes excessive memory and CPU. Developers on older laptops or lower-end machines will experience constant lag and freezes. Lightweight alternatives like Thunder Client or Hoppscotch are better choices.
- **Developers in air-gapped or offline environments** — Avoid: Postman requires internet connection and login to function. Developers in secure corporate environments, air-gapped networks, or frequently offline situations cannot use Postman effectively. Bruno works entirely offline.
- **Solo developers doing simple API testing** — Avoid: For basic REST API testing, Postman is overkill. The bloat, account requirement, and resource consumption aren't worth it for simple use cases. Thunder Client, Hoppscotch, or even curl are better for quick API calls.
- **Teams needing Git-based API workflow** — Depends: While Postman has Git integration, Bruno stores collections as files that work natively with Git. Teams that want collections versioned alongside code may prefer Bruno's approach over Postman's cloud-centric model.
- **Enterprise teams needing full API lifecycle management** — Good fit: Large organizations needing API design, testing, documentation, mocking, and monitoring in one platform benefit from Postman's comprehensive features. SSO, audit logs, and governance features support enterprise requirements.
- **Teams already invested in Postman ecosystem** — Good fit: Organizations with existing Postman collections, established workflows, and team familiarity may find migration costs outweigh Postman's drawbacks. The switching cost is real for large API portfolios.
- **QA teams doing automated API testing** — Good fit: Postman's test scripting, collection runner, and Newman CLI integration support automated API testing workflows. Teams already doing CI/CD integration benefit from the established tooling.

## Alternatives

- **Bruno**: Bruno was created specifically by developers frustrated with Postman's bloat. It's open-source, stores collections as files (Git-friendly), works offline, and requires no account. The most popular switch for developers who want simplicity.

## FAQ

### Why is Postman so slow and laggy?

Postman is built on Electron which is resource-heavy. Over time, the app has added many features causing bloat. It can take 14+ seconds to start and consumes excessive memory. Solutions: clear cache regularly, reduce open tabs, or switch to lightweight alternatives like Bruno or Thunder Client.

### Can I use Postman without signing in?

No, as of version 10, Postman requires account creation and login to use. You cannot save requests to collections without signing in. This was a controversial change that pushed many developers to alternatives like Bruno (no account required) or Thunder Client.

### Why does Postman use so much memory and CPU?

Postman is an Electron app that runs a full Chromium browser instance. Combined with feature bloat, it consumes 500MB+ RAM and spikes CPU to 50-60% even when idle. Large workspaces make this worse. Developers report needing to restart Postman frequently to reclaim resources.

### Is Postman free for individuals?

Postman has a free tier but with significant limitations. As of March 2026, the free plan is limited to 1 user only. You get basic API testing but limited collection runs, no team features, and restricted monitor/mock server usage. Many features require paid plans starting at $14/user/month.

### Is Postman safe for sensitive API data?

Postman syncs data to their cloud servers by default when you sign in. This raises privacy concerns for sensitive API keys, proprietary endpoints, or client data. Alternatives like Bruno store everything locally with no cloud sync. For sensitive work, consider local-first tools.

### What are the best Postman alternatives?

Top alternatives: Bruno (open-source, offline, Git-friendly, no account needed), Insomnia (clean UI, GraphQL support), Thunder Client (VS Code extension, lightweight), Hoppscotch (web-based, fast). Bruno is the most popular switch for developers frustrated with Postman's bloat.

### Why did Postman remove offline mode?

Postman removed offline mode in version 10 to push users toward their cloud platform and collaboration features. The company wants data synced to their servers. This decision frustrated many developers, especially those in corporate environments with network restrictions. Bruno was created partly in response to this change.

### Is Postman worth it for teams?

At $14-49/user/month, Postman costs add up quickly. A 10-person team pays $1,680-5,880/year. For basic API testing, it's overkill. However, teams needing API governance, documentation, mocking, and monitoring in one platform may find value. Evaluate if you actually need all the features.

### Why did Postman lose my collections?

Postman can lose collections when: refusing account creation during updates, sync conflicts between team members, or app crashes before sync completes. Since v10 requires login, unsynced data may be lost. Always export collections as backup. Consider Bruno which stores collections as local files.

### Does Postman work offline?

Not effectively. Postman requires login and many features need internet connectivity. You can make basic API calls offline if already logged in, but collection management and sync features don't work. For true offline usage, use Bruno which works entirely locally without any account requirement.

### How do I export Postman collections to other tools?

Export via Collections > Export as JSON (v2.1 format). Most alternatives like Bruno, Insomnia, and Hoppscotch can import Postman collections. Bruno even has an automatic import feature. Export your data before switching - many users regret not backing up before Postman updates.

### Is Bruno better than Postman?

For many developers, yes. Bruno is lightweight, stores collections as local files (Git-friendly), requires no account, works offline, and is open-source. It lacks some advanced features like mock servers and monitors, but for API testing, it's faster and simpler. The developer community increasingly recommends Bruno.

### Why is Postman considered bloated?

Postman started as a simple Chrome extension for API testing. It's now a full platform with API design, documentation, mocking, monitoring, collaboration, and more. For developers who just want to test APIs, 90% of features are unnecessary. The app size, resource usage, and complexity have grown significantly.

### How do I cancel Postman subscription?

Go to Settings > Billing > Cancel subscription. However, users report cancellation requests don't always process properly through the website. Some report waiting 2+ weeks with requests remaining unprocessed. Contact support directly if website cancellation fails, especially before renewal dates.
