TL;DR
Postman spent years adding flows, AI assistants, monitoring dashboards, and governance controls on top of what started as a simple HTTP client. The result is a tool that’s slower to open, harder to navigate, and frustrating to use for basic API testing. Developers who want a fast, focused workflow are switching to alternatives like Apidog that cover the full API lifecycle without the overhead.
Introduction
Postman was once the gold standard. You opened it, pasted a URL, hit Send, and got a response. That simplicity earned it hundreds of millions of downloads and a loyal developer following.
Then came the pivot.
Starting around 2021, Postman began repositioning itself as an “API platform” – not just a client. It acquired companies, added enterprise governance features, and launched Postman Flows, a visual workflow builder aimed at non-developers. The free tier got tighter. The app got heavier. And developers started asking a question that would have seemed strange five years ago: is there something better?
The answer, for a growing number of teams, is yes. This article explains why Postman’s product strategy created a gap, and what filling that gap looks like.
What Postman added (and why it slowed things down)
Postman’s current feature list is long. Here’s what has been added in recent years beyond the core HTTP client:
- Postman Flows: a node-based visual programming canvas for chaining API calls without code
- Postman AI: “Postbot,” an AI assistant that can generate tests, write descriptions, and suggest fixes
- API governance and linting: organization-wide rules for API design standards
- Mock servers: hosted mocking with usage limits on free accounts
- Monitors: scheduled collection runs with dashboards
- API security auditing: integrations with security scanning tools
- Workspaces and role-based access: enterprise access controls
None of these features are bad on their own. The problem is that they all ship inside the same Electron app. Every user, including someone who just wants to send a POST request, loads this entire feature set at startup.
The result is measurable. Postman’s app regularly takes 10-15 seconds to open on mid-range hardware. On Fedora and other Linux distributions, startup crashes were common enough in 2023 and 2024 that they became a running complaint on Reddit’s r/webdev and r/programming. The app’s memory footprint on idle can exceed 400 MB.
One developer on Hacker News summarized it plainly: “I just want to send HTTP requests. I don’t need a visual programming canvas.”
The “everything app” trap
There’s a well-documented product pattern where a tool adds features to capture more of the enterprise market, and in doing so, alienates the developers who made it popular in the first place. Postman is following that pattern.
The free tier limits tell the story. As of 2025:
- Mock server calls are capped at 1,000 per month on free plans
- Monitors are limited to 1,000 calls per month
- Collection runs via the API are rate-limited
- Some governance features are enterprise-only
These limits make sense from a business perspective. Postman needs revenue. But they create friction for individual developers and small teams who relied on those features being free. And the pricing structure is complex enough that developers frequently report confusion about what’s included in which tier.
The UX complexity compounds the performance issue. When you add Flows, AI suggestions, governance linting, and workspace management to a tool designed around HTTP requests, the navigation becomes cluttered. New users struggle to find basic settings. The right-click context menu in the collection panel now has more than a dozen options. Simple tasks take more clicks than they used to.
Why developers are leaving
The exit pattern follows a consistent arc. Developers don’t usually leave Postman the first time it crashes. They leave when they realize they’re spending mental energy on the tool instead of the API they’re building.
Common triggers reported on developer forums:
Startup time. On a laptop with 16 GB of RAM, Postman often takes longer to open than VS Code with five extensions loaded. When you’re context-switching constantly, that lag adds up.
Sync conflicts. Postman’s cloud sync has a history of silently overwriting local changes when multiple team members edit the same collection. Recovering from a sync conflict requires digging through version history, which is a paid feature.
Newman limitations. Postman’s CLI test runner, Newman, depends on npm. That means it introduces npm into CI/CD pipelines that would otherwise have no Node.js dependency. Supply chain risk is a real consideration for security-conscious teams.
Feature noise. Postbot suggestions appear in places that interrupt flow. The AI panel loads even when you don’t use it. The Flows canvas is always one click away, taking up screen real estate.
Free tier pressure. Developers who built workflows around Postman’s free features have had to renegotiate those workflows as limits tightened over time.
What a focused alternative looks like
Apidog takes a different approach. It covers the same full lifecycle – design, test, mock, docs – but it was built as an integrated system rather than a point tool with features bolted on.
Key differences that matter for day-to-day work:
No npm dependency for CI/CD. Apidog’s CLI runner handles collection execution in CI pipelines without requiring Node.js or npm. That removes an entire dependency category from your pipeline.
Local-first storage. Collections, environments, and test suites are stored locally by default. Cloud sync is optional, which means you don’t lose work to a sync conflict. Your data stays on disk unless you choose otherwise.
Import from Postman. If you have existing Postman collections, Apidog imports them directly, including environments and test scripts. The migration path is low-friction.
No run limits. There are no caps on collection runs, mock server calls, or test executions on any plan. Teams running high-volume test suites don’t need to watch a usage counter.
Faster startup. Because Apidog doesn’t load a visual programming canvas and AI layer at boot, it opens in under three seconds on the same hardware where Postman takes fifteen.
Free for teams up to three users. The core platform – design, test, mock, docs – is free for teams of three without feature degradation.
What Postman still does well
This isn’t a dismissal of Postman. It still has a large ecosystem. The collection format is an industry standard. Newman, despite its npm dependency, is widely understood and has extensive documentation. The Postman API network provides public collections for thousands of APIs.
If your team is already deep in the Postman ecosystem, the switching cost is real. But if you’re starting fresh, or if you’re evaluating tooling because Postman’s current trajectory is causing friction, the alternatives have caught up.
FAQ
Why did Postman add so many features?Postman raised significant venture funding and needed to expand its addressable market beyond individual developers. Enterprise buyers want governance, monitoring, and compliance features, which drove the product roadmap away from the core HTTP client experience.
Is Postman’s Flows feature actually useful?Some non-developer personas, such as QA leads building chained API tests without writing code, find Flows helpful. For developers comfortable with JavaScript or Python, it adds little over writing a test script directly.
Does Apidog support all Postman test scripts?Apidog supports the Postman scripting API, including pm.test, pm.expect, pm.environment.set, and pm.response. Most test scripts migrate without changes. Edge cases involving third-party libraries loaded via pm.require may need adjustment.
Is the Postman free tier still usable?For basic HTTP testing and collection organization, yes. For teams that need mock servers, monitoring, or API-driven collection runs, the free tier limits become a constraint quickly.
What’s the migration path from Postman to Apidog?Export your Postman collections as JSON, then import them into Apidog using File > Import. Environments import the same way. The process takes minutes for most workspaces.
Does Apidog have an AI assistant?Yes. Apidog includes an AI assistant for generating test cases, writing endpoint descriptions, and suggesting request parameters. It’s built in, not a separate loading panel.
The developer tool market has a long history of incumbents losing ground when they prioritize enterprise expansion over the developer experience that made them successful. Postman isn’t dead – but the gap between what developers want and what Postman now provides is wide enough that switching has become a rational choice rather than an extreme one.
