You’ve probably felt it: Postman keeps getting heavier, slower, and more account-gated with every release. What started as a lightweight REST client is now a bloated SaaS platform that wants you to log in before you can test a simple endpoint. Meanwhile, Bruno has been quietly building a fanbase among developers who are tired of the enterprise creep. So which one should you actually be using in 2026?

I’ve been running both tools in parallel across three different projects — a microservices backend, a public REST API, and an internal GraphQL service — for the past several months. Here’s the honest breakdown.

What Is Bruno and Why Is Everyone Talking About It?

Bruno is an open-source API client built by Anoop M D and released in 2022. It stores your API collections as plain text files in a format called Bru — a simple, human-readable markup language — directly on your filesystem. No cloud sync, no account required, no proprietary binary blobs. Just folders and files you can commit to Git like any other code.

That’s the entire pitch, and it turns out that pitch resonates hard with developers who’ve been burned by Postman’s shift toward SaaS-first design. Bruno hit 30k GitHub stars faster than most developer tools reach 1k. As of 2026, it’s crossed 50k stars and has an active contributor base that ships updates frequently.

What Is Postman (in 2026)?

Postman needs no introduction, but it’s worth acknowledging how much it’s changed. The Postman of 2026 is a full API platform — it includes API design, mocking, monitoring, automated testing pipelines, documentation generation, and team collaboration features. It’s powerful, but it’s also a product that’s clearly optimized for enterprise sales, not individual developer happiness.

The free tier still exists, but it’s increasingly limited. Collections sync to the cloud by default, the desktop app requires a login since version 10, and some features that used to be free are now paywalled. If you’re a solo dev or a small team, you’re paying for a lot of platform you’ll never use.

Bruno vs Postman: Feature-by-Feature Breakdown

1. Collection Storage and Git Integration

This is where Bruno wins decisively and it’s not close.

In Postman, your collections live in Postman’s cloud. You can export them as JSON, but that’s a manual step, the format is verbose, and diffs are nearly unreadable. Postman does have Git sync for collections (available on paid plans), but it’s a bolt-on feature that feels awkward — you’re syncing a proprietary format to Git rather than Git being the native storage layer.

Bruno stores every request as a .bru file in a folder on your machine. Here’s what a typical Bruno request file looks like:

meta {
  name: Get User
  type: http
  seq: 1
}

get {
  url: {{baseUrl}}/users/{{userId}}
  body: none
  auth: bearer
}

headers {
  Accept: application/json
}

auth:bearer {
  token: {{authToken}}
}

That’s readable. That’s diffable. You can review API changes in a pull request the same way you review code changes. For teams that care about API-as-code, this is a game changer. I’ve caught breaking API changes in code review that would have slipped through if we were still using Postman collections.

2. Performance and Resource Usage

Postman is an Electron app, and it shows. On my M2 MacBook Pro, Postman regularly sits at 400–600MB of RAM just idling. Startup time is 8–12 seconds. It’s not catastrophic, but it’s noticeable when you’re switching between tools throughout the day.

Bruno is also Electron-based (it’s a JavaScript ecosystem, after all), but it’s significantly lighter. RAM usage hovers around 150–250MB in my testing, and startup is under 4 seconds. When you’re opening and closing your API client dozens of times a day, that adds up.

3. Scripting and Test Automation

Postman has a mature scripting environment. Pre-request scripts and test scripts run in a sandboxed JavaScript environment, you get the pm object with a rich API, and there’s a massive library of community examples. Running collections via Newman (Postman’s CLI runner) in CI/CD pipelines is well-documented and battle-tested.

Bruno’s scripting is improving fast but is still playing catch-up. You write scripts in JavaScript using a bru object that mirrors much of Postman’s pm API, which makes migration easier. The Bruno CLI (@usebruno/cli) lets you run collections in CI. I’ve used it successfully in a GitHub Actions pipeline — it works, but the documentation is thinner and you’ll hit edge cases that require digging through GitHub issues to solve.

Verdict: Postman is more mature here. If your team has complex test automation with hundreds of assertions and custom scripts, migrating to Bruno will take real effort.

4. Environment and Variable Management

Both tools handle environments and variables well. Postman’s environment management is more polished — you can have multiple environments, switch between them easily, and share them with team members via the platform.

Bruno handles environments as .bru files too, which means they live in your repo. One important distinction: Bruno has a concept of “secret” variables that are stored locally and not committed to Git. This is actually a smart design — your base_url goes in the repo, your auth_token stays local. Postman has a similar concept with initial vs current values, but it’s more confusing to explain to new team members.

5. GraphQL Support

Both tools support GraphQL. Postman has schema introspection, query autocomplete, and a decent GraphQL editor. Bruno’s GraphQL support is functional — you can send queries, use variables, set headers — but the introspection and autocomplete features are less polished. If GraphQL is your primary use case, Postman still has the edge.

6. Collaboration Features

Postman’s collaboration model is built around its cloud platform. Workspaces, shared collections, comments on requests, API documentation generation — it’s all there and it works well for teams that are bought into the Postman ecosystem.

Bruno’s collaboration model is Git. That’s it. If your team uses Git (and you should), you get collaboration for free. No per-seat pricing, no workspace limits, no vendor lock-in. The tradeoff is that you lose Postman’s purpose-built collaboration UX — there’s no commenting on requests, no visual diff in the app.

7. API Documentation

Postman generates hosted API documentation from your collections. It’s genuinely useful for sharing API docs with external consumers or non-technical stakeholders.

Bruno doesn’t have this. If documentation generation is a core part of your workflow, Bruno isn’t a complete replacement yet. You’d need a separate tool like Swagger UI or Redoc fed by an OpenAPI spec.

Pricing Breakdown

Bruno Pricing

Bruno is free and open source. The core application is MIT-licensed and available on GitHub. There’s a Bruno Golden Edition — a one-time purchase (around $19 at the time of writing) that unlocks some premium features and supports the project financially. It’s not required for the core functionality. This is the right pricing model for a developer tool: free to use, pay if you want to support the project and get extras.

Postman Pricing (2026)

• Free tier: 3 collaborators, 1,000 monthly API calls for monitors, limited mock server calls, limited API documentation views
• Basic plan: $14/user/month — unlimited collections, more monitor calls, version control integration
• Professional plan: $29/user/month — custom domains for docs, SSO, audit logs, increased limits
• Enterprise: Custom pricing — dedicated support, advanced security, unlimited everything

For a team of 5 developers on the Basic plan, that’s $70/month or $840/year. For the Professional plan, it’s $145/month or $1,740/year. These aren’t bank-breaking numbers for a funded startup, but they’re real money for a bootstrapped project or side hustle.

Migrating from Postman to Bruno

Bruno supports importing Postman collections directly. Go to File → Import Collection → Postman and drop in your exported JSON. In my testing, simple collections migrate cleanly. Complex collections with lots of scripts require manual cleanup — some pm.* methods don’t have direct Bruno equivalents yet, and you’ll need to remap them to bru.* calls.

My recommendation: don’t try to migrate everything at once. Start new projects in Bruno, and migrate old Postman collections opportunistically when you’re actively working on them. A cold migration of a 200-request collection with 50 test scripts is a weekend project, not an afternoon.

Use Bruno If…

• Your team uses Git and wants API collections treated like code
• You’re working on an open-source project and don’t want to force contributors to create Postman accounts
• You’re privacy-conscious and don’t want your API requests synced to a third-party cloud
• You’re a solo developer or small team and can’t justify Postman’s per-seat pricing
• You want to support open-source tooling in your stack
• You work offline frequently (flights, poor connectivity, air-gapped environments)

Use Postman If…

• Your team is already deeply embedded in the Postman ecosystem with years of collections and scripts
• You need hosted API documentation for external consumers
• You rely on Postman’s mock server feature for frontend development
• You have complex GraphQL workflows that need schema introspection and autocomplete
• Your organization requires SSO, audit logs, or enterprise compliance features
• Your QA team has built extensive Newman-based CI pipelines that would be painful to rewrite

The Bigger Picture: What This Shift Means

Bruno vs Postman isn’t just a tool comparison — it’s a proxy for a broader debate about SaaS creep in developer tooling. Postman followed the same playbook as many dev tools: start simple, gain adoption, raise VC funding, add enterprise features, restrict the free tier, push users toward the cloud platform. It’s a legitimate business strategy, but it’s also why developers keep looking for alternatives.

Bruno represents a different philosophy: local-first, Git-native, open-source. It’s the same energy driving tools like MCP servers for coding agents — developers want tools that integrate with their existing workflows rather than pulling them into a new platform ecosystem.

The risk with Bruno is sustainability. Open-source developer tools have a graveyard of abandoned projects. The Golden Edition revenue model is promising, but it’s not venture-scale funding. If the core contributors burn out or get hired away, the project could stall. Postman, whatever its flaws, isn’t going anywhere.

That said, Bruno’s GitHub activity is healthy, the community is active, and the momentum is real. I’m comfortable recommending it for production use in 2026 — with the caveat that you should stay close to the changelog and have a contingency plan.

If you’re thinking about your overall dev infrastructure stack alongside tools like this, it’s worth reading our DigitalOcean vs Hetzner vs Vultr comparison — same principle applies: don’t let convenience lock you into a platform that’ll squeeze you later. Speaking of which, if you do need reliable hosting for your API backends, DigitalOcean offers a solid $200 credit for new accounts that makes spinning up a test environment essentially free for months.

Final Recommendation

If you’re starting a new project in 2026, use Bruno. The Git-native workflow is genuinely better for team collaboration, the privacy story is cleaner, and the cost is zero. The missing features (mock servers, hosted docs, mature GraphQL tooling) are real gaps, but most teams don’t need all of them.

If you’re on an existing team with years of Postman investment, don’t migrate for the sake of it. Evaluate the specific pain points you’re hitting. If your main complaint is cost, run the numbers — a team of 3 on Bruno saves $500+/year. If your main complaint is the login requirement, that’s not going away from Postman. If your main complaint is Git integration, that’s the exact problem Bruno was built to solve.

The developer tool landscape is shifting toward local-first, open-source, and Git-native. Bruno is ahead of that curve. Postman is a mature, feature-complete platform that’s optimizing for enterprise contracts. Both can be the right answer — it just depends on which problems you’re actually trying to solve.

For most developers reading this: you should try Bruno this week. It takes 10 minutes to install and import a collection. You’ll know within an hour whether it fits your workflow.
