massCode vs Bruno
Bruno and massCode both keep API work local, work offline, and let you use your own files and Git workflow. If you are considering a Bruno alternative, the main question is whether you want a dedicated API client or API testing inside a broader developer workspace.
Bruno focuses on API collections, testing, and command-line automation. massCode's HTTP space combines saved requests, environments, assertions, JavaScript tests, and a desktop folder runner with snippets, notes, and tasks. Local-first storage is common ground; the surrounding workflow is the difference.
Try massCode: import one collection, run a short request flow, and keep the related code and notes alongside it.

Bruno documents its local collection model and MIT core license. HTTP, GraphQL, gRPC, scripting, and testing are included in its free offering; see Bruno pricing for current paid enhancements.
Where Bruno fits better
- API automation beyond the desktop. Bruno's Collection Runner and CLI let you run collections locally or in CI/CD pipelines. massCode's Folder Runner runs inside the app.
- Dedicated API workflows. If requests and test suites are the whole job, Bruno keeps that work in a purpose-built client. Its local collection files fit a repository-based workflow without needing a broader workspace.
- Broader authentication and gRPC. Bruno provides built-in authentication options such as OAuth 2.0, and supports gRPC. massCode provides inherited auth, Basic, Bearer, and API Key, but has no OAuth flow or gRPC client.
Where massCode fits better
- Requests alongside the rest of your project context. Keep API examples near snippets, notes, and tasks, with calculations, drawings, and developer tools available in the same app.
- A shared Markdown Vault. HTTP requests use the same local storage and folder-based backup or sync workflow as the rest of your massCode content.
- Code ready to reuse. Generate request snippets for cURL, JavaScript, Python, and other clients, then keep useful code in your snippet library.
API tools in the workspace
- Reusable collection setup. Define shared auth, headers, variables, scripts, and checks at collection or folder level. Requests inherit that setup and can override auth and headers.
- Local request flows. Check responses with assertions and extraction, add trusted JavaScript tests, and run saved requests with Folder Runner. The variables inspector helps track environment and temporary Session values while sending requests manually.
- Request debugging. Inspect saved request and response snapshots, view network traffic in Console, and manage cookies and per-request transport settings.
Honest trade-offs
Both tools offer local files and offline work, so switching to massCode is primarily a choice to bring API work into your developer workspace. Bruno is the more direct fit when you need a dedicated client with CLI/CI automation.
massCode's Folder Runner supports up to 500 saved HTTP requests, including nested folders and GraphQL requests. GraphQL is limited to POST queries and mutations, without subscriptions or schema introspection. WebSocket handles text/JSON messages but does not participate in tests, scripts, or folder runs. massCode has no standalone CI runner, mock servers, or scheduled monitors.
Requests, scripts, and regular environment values in massCode are plain text. Use secret variables for credentials: values are encrypted using the operating system, stored outside the vault, and entered separately on each device. Linux requires a supported keyring. Review imported data before syncing or committing it.
Migrating from Bruno to massCode
Export a Bruno collection as OpenCollection YAML or an OpenCollection ZIP archive, then select it in massCode's HTTP import dialog. Native .bru files and ZIP archives containing .bru files are not supported import formats.
Preview shows imported items and compatibility warnings. Supported declarative assertions and a limited subset of scripts are converted to massCode rules and its mc API. Unsupported active scripts block the affected request until you adapt the code and remove the blocker. Imported code requires explicit local trust before execution; trust alone does not fix incompatible scripts.
Review inherited auth on each request; imported API keys become header or query entries. Bruno GraphQL bodies import as JSON with a warning. Collection variables may become a separate environment, and inherited scripts are copied into requests. Select the environment you need, protect credentials, and verify a complete flow before using Folder Runner. See Importing HTTP Collections for export steps and compatibility details. Keep your original Bruno collection: importing creates new massCode items rather than a live link to those files.
Who should pick which
- Pick Bruno if you want a dedicated local-first API client, repository-based collections, broader built-in auth, and a CLI for CI workflows.
- Pick massCode if you want local API testing inside the same free workspace as your snippets, notes, and tasks.
- Use both if Bruno runs your project's API suite while massCode stores request examples and implementation context.
Frequently asked questions
Is massCode an open-source Bruno alternative?
Yes, for local API development inside a broader workspace. massCode is free under AGPL v3, while Bruno's core is MIT-licensed. Both are local-first; choose based on workspace integration versus dedicated API tooling and CLI automation.
Does Bruno require a cloud account?
Bruno's core API workflow is local and offline, without an account requirement. Its repository describes its filesystem-based, Git-friendly approach. Moving to massCode does not introduce local-first storage as a new capability; it adds the surrounding developer workspace.
Can massCode import native Bruno .bru files?
No. Export your collection as OpenCollection YAML or an OpenCollection ZIP first. Review the import guide for supported assertions, script conversion, and migration limits.
Can massCode run API tests like Bruno?
massCode supports response assertions, extraction, trusted JavaScript tests, and sequential folder runs in the desktop app. It does not replace Bruno's command-line runner or CI integration. The two scripting APIs are different, so imported tests may need adaptation.
