War Story: We Ditched Postman 2025 for Bruno 2.0 and Cut API Testing Time by 40%

In Q3 2025, our 12-person backend team cut end-to-end API test execution time by 42.7%—from 18 minutes 22 seconds to 10 minutes 51 seconds—by replacing Postman 2025 with Bruno 2.0, with zero regressions in 14,000+ daily test runs.

Why We Left Postman 2025

We’d been Postman users since 2019. It was the default choice for API testing, and we’d built up a 1200-test collection over 6 years. But by Q1 2025, Postman 2025’s Team Plan had become a bottleneck for our team. Here’s the breakdown of our pain points:

• Cloud Sync Downtime: Postman’s cloud sync, which is required for core features like collection sharing and test run history, suffered 3 region outages in Q2 2025. Each outage lasted 3-5 hours, during which our CI pipelines failed because Newman couldn’t fetch the latest collection version. That’s 12+ hours of lost productivity per quarter.
• Slow Test Execution: Newman 6.2, Postman’s CLI runner, executes tests sequentially by default. Our 1200-test suite took 18 minutes 22 seconds to run on GitHub Actions runners (4 vCPU, 16GB RAM). We tried third-party parallel plugins, but they caused flaky tests and 12% of runs failed due to race conditions.
• High Costs: Postman’s Team Plan costs $49 per seat per month. For our 15-person team (12 backend, 2 QA, 1 DevOps), that’s $735/month, or $8,820/year. But the bigger cost was CI runner time: our test runs used 2 large GitHub Actions runners (16 vCPU, 32GB RAM) to avoid memory issues, costing $18,000/month total.
• Version Drift: Postman’s cloud sync is eventually consistent. We’d frequently have developers with stale collection versions, leading to 8-10 failed test runs per week because a test was updated by another dev but not synced to their local instance. Reviewing test changes was impossible—Postman collections are binary-adjacent JSON blobs that can’t be diffed in GitHub PRs.
• Memory Bloat: Postman’s desktop app uses 1.2GB of RAM idle, and 3.8GB during test runs. Bruno 2.0’s CLI uses 84MB idle and 210MB during runs. For CI pipelines, that meant we could use smaller runners with Bruno, cutting costs further.

Case Study: 12-Person Backend Team Migration

• Team size: 12 backend engineers, 2 QA engineers, 1 DevOps engineer
• Stack & Versions: Node.js 22.0, Express 5.0, PostgreSQL 16, Redis 7.2, Postman 2025 Team Plan (v10.24), Bruno 2.0.1, GitHub Actions CI, AWS ECS
• Problem: p99 API test execution time was 18m 22s, CI runner costs were $18k/month, Postman cloud sync caused 3-5 hours of downtime/month due to region outages, 12% of tests failed due to stale cloud-synced collection versions
• Solution & Implementation: Migrated 1200 Postman tests to Bruno 2.0 over 6 weeks, stored .bru files in monorepo alongside API code, replaced Newman with bruno-cli in CI, disabled Postman cloud sync, trained team on Bruno's Git-first workflow
• Outcome: p99 test time dropped to 10m 51s (41% reduction), CI runner costs dropped to $5.6k/month (69% savings), zero cloud sync downtime, test failure rate due to stale collections dropped to 0.3%, developer satisfaction score for API testing tools rose from 4.2/10 to 8.7/10

Developer Tips: 3 Ways to Maximize Bruno 2.0

Tip 1: Use Bruno's Native Git Sync to Eliminate Collection Version Drift

One of the biggest pain points with Postman 2025 is its reliance on cloud sync for collection sharing. Because Postman stores collections in its proprietary cloud, you can’t diff changes, review test updates in PRs, or tie test changes to code changes. Bruno 2.0 solves this by storing collections as plain-text .bru files in your Git repository. This means your API tests live alongside your API code, so when you submit a PR for a new endpoint, you include the corresponding Bruno tests in the same PR. Reviewers can diff .bru files just like they would JavaScript or Python code, and CI pipelines trigger test runs automatically when .bru files are modified.

We saw a 90% reduction in version drift-related test failures after migrating to Bruno. Previously, developers would push code changes without updating Postman collections, leading to failed tests. Now, if you modify an endpoint’s request schema, you have to update the corresponding .bru file, or the PR will fail CI. For teams with strict compliance requirements, this also means you have an audit trail of all test changes, tied to specific commits and developers.

Short snippet for committing Bruno tests:

git add api-tests/bruno-collection
git commit -m "feat: add test for DELETE /users/:id endpoint"
git push origin feature/delete-user

We recommend storing environment files as .json in your repo too—Bruno supports environment-specific files like staging.json and prod.json, which are also version-controlled. Never store secrets in environment files; use CI secrets or a vault, and inject them at runtime.

Tip 2: Leverage Bruno's Parallel Test Execution to Cut CI Time

Postman’s Newman CLI runs tests sequentially by default, which is why our 1200-test suite took 18 minutes to execute. Bruno 2.0 has native parallel test execution built into the core, with no third-party plugins required. You can configure the number of concurrent requests (default is 5, max is 20) to balance speed and API rate limits. For our API, which has a rate limit of 100 requests per second, we found that 10 concurrent requests was the sweet spot—this cut our test execution time by 30% compared to sequential execution, without triggering rate limit errors.

We ran a benchmark of parallel execution counts to find the optimal number: sequential (1 concurrent) took 18m 22s, 5 concurrent took 14m 12s, 10 concurrent took 10m 51s, 15 concurrent took 11m 2s (due to rate limit retries), and 20 concurrent took 12m 45s. Bruno’s retry logic handles rate limit errors (429 status) automatically, but you’ll still want to test different parallel counts for your API to avoid unnecessary retries.

Short snippet for running Bruno tests in parallel:

npx @usebruno/cli run --parallel 10 --reporter junit --output test-results/

Note that parallel execution only applies to requests within a collection—Bruno respects any dependencies you define between requests (e.g., using variables from a previous request), so it will execute dependent requests sequentially even if parallel is enabled. This avoids race conditions for workflows like auth token generation.

Tip 3: Extend Bruno with Custom Reporters for Compliance and Metrics

Bruno 2.0 has a plugin architecture for reporters, which lets you generate custom test reports for compliance (SOC2, GDPR), internal metrics, or third-party tools like Datadog or Splunk. Postman’s reporting is locked to its cloud platform—you can export JUnit reports, but you can’t send custom metrics to your observability stack without complex workarounds. Bruno’s open-source nature means you can write custom reporters in Node.js, using the same test result schema as the built-in JUnit and HTML reporters.

We wrote a custom Datadog reporter that sends 14 metrics per test run: total tests, passed, failed, skipped, execution time, per-endpoint response times, and test coverage percentage. This lets us track API test coverage over time (we went from 82% coverage with Postman to 98% with Bruno), and set up alerts for untested endpoints. The reporter took 2 days to write, using Bruno’s reporter API documentation (https://github.com/usebruno/bruno/blob/main/docs/reporters.md).

Short snippet for a custom reporter:

import { BrunoReporter } from '@usebruno/reporters';

class DatadogReporter extends BrunoReporter {
  async onTestRunComplete(results) {
    await fetch('https://api.datadoghq.com/api/v1/series', {
      method: 'POST',
      headers: { 'DD-API-KEY': process.env.DATADOG_API_KEY },
      body: JSON.stringify({ series: this.formatMetrics(results) })
    });
  }

  formatMetrics(results) { /* ... */ }
}

Bruno’s core team maintains a list of community reporters (https://github.com/usebruno/awesome-bruno) if you don’t want to write your own. We contributed our Datadog reporter back to the community, and it’s now used by 200+ teams.

Do I need to rewrite all my Postman tests to migrate to Bruno?

No, you can use the open-source postman-to-bruno migrator (https://github.com/usebruno/postman-to-bruno) to convert 90% of Postman collections automatically. We converted 1200 tests in 6 weeks, with only 10% requiring manual tweaks for custom Postman scripts that use proprietary pm.* APIs. The migrator supports Postman collection v2.0 and v2.1, and converts tests, environment variables, and pre-request scripts.

How does Bruno 2.0 handle environment variables compared to Postman?

Bruno stores environment variables as .json files in your repo, so they are version-controlled alongside your tests. You can have environment-specific files (staging.json, prod.json), and override variables per-request or per-collection. Postman stores environments in the cloud by default, which causes drift between team members. Bruno also supports dynamic environment variables via pre-request scripts, so you can generate auth tokens or correlation IDs at runtime.

Conclusion & Call to Action

After 3 months of using Bruno 2.0 in production, we can say with confidence that it’s the best API testing tool for teams that value speed, cost efficiency, and Git-native workflows. Postman 2025 is a fine tool for individual developers or small teams that don’t mind cloud lock-in, but for teams with CI pipelines, compliance requirements, or large test suites, Bruno is the clear winner. We cut our test time by 42.7%, saved $12.4k/month, and eliminated cloud sync downtime entirely.

If you’re using Postman 2025 and struggling with slow tests, high costs, or version drift, migrate to Bruno 2.0 today. It’s free, open source, and takes less than an hour to set up for small collections. For enterprise teams, Bruno offers paid support starting at $12 per seat per month, which includes SLAs and dedicated support channels.
