hoppscotch

Hoppscotch is an open-source API development platform that replaces Postman/Insomnia with offline, on-premise, and cloud options. It supports REST, GraphQL, WebSocket, Server-Sent Events, Socket.IO, and MQTT, available as a web app, desktop client, and CLI.

What hoppscotch is

TypeScript-based PWA and SPA built with Vue.js offering HTTP client functionality with pre/post-request scripting, environment variables, collections management, and team collaboration features. Deployable as web, desktop, or CLI with local/cloud sync capabilities.

Best use cases

API Development & Testing Workflow

Teams building and testing REST/GraphQL APIs benefit from request organization, automated testing via post-request scripts, environment variable management, and real-time collaboration without vendor lock-in.

Offline-First Development Teams

PWA architecture with offline support enables developers to work without internet, particularly valuable for field teams, CI/CD pipelines, and organizations with connectivity constraints or air-gapped networks.

Self-Hosted Enterprise Deployments

On-premise deployment option allows enterprises to maintain API tooling within their infrastructure, meeting data residency, compliance, and security requirements while avoiding SaaS vendor dependencies.

Implementation considerations

Decide between cloud-hosted, self-hosted, or hybrid deployments early; architecture differs in authentication, sync backend, and operational overhead.
Plan environment variable and pre-request script strategy upfront; complex automation logic requires JavaScript proficiency and careful testing to avoid request/response errors.
Assess proxy needs: official Hoppscotch proxy fixes CORS and HTTP-only API issues, but self-hosted deployments require separate proxy infrastructure (proxyscotch) or equivalent.
Team role-based access control requires clear governance: define workspace/collection ownership, permissions model, and audit logging expectations before rollout.
CLI integration into CI/CD pipelines requires scripting knowledge and test collection setup; validate performance in your pipeline before production deployment.

When to avoid it — and what to weigh

Requires Enterprise Single Sign-On Without Configuration — SSO support is marked as Enterprise Edition only; standard deployments rely on GitHub, Google, Microsoft, or email authentication. Custom SSO integration requires evaluation of enterprise licensing.
Need Built-In Load Testing or Performance Profiling — Hoppscotch focuses on API development and functional testing. Specialized load testing, JMeter integration, or advanced performance analysis tools are not documented; these require external services.
Legacy Non-Browser Environments Only — While CLI exists, primary UX is web/desktop PWA. Teams requiring pure headless, non-JavaScript tooling for API testing may find the architecture misaligned with their operational model.
No Need for Team Collaboration or Sync — If working solo with static API workflows and no multi-device sync requirement, lighter alternatives may reduce operational overhead. Hoppscotch's team/sync features may be over-provisioned.

License & commercial use

MIT License (OSI-compliant, permissive). Allows modification, commercial use, distribution, and private use with no warranty. Attribution required but non-restrictive. No copyleft obligations.

MIT License permits commercial use without restriction. However, verify whether enterprise features (SSO, advanced admin dashboard, team limits) are included in the open-source build or require separate licensing; official documentation should clarify community vs. enterprise feature gates.

Security considerations

No exploit details provided. Considerations: (1) OAuth 2.0/OIDC and Bearer token support mitigate credential exposure in transit. (2) Pre-request/post-request scripting executes JavaScript; malicious or poorly written scripts could expose environment variables or credentials. (3) Proxy mode centralizes CORS/HTTP traffic; verify proxy server privacy policy and data handling. (4) Cloud sync backend (if used) requires TLS/encryption in transit; self-hosted deployments must enforce HTTPS and secure sync backend. (5) No mention of audit logging or request/response encryption at rest. Evaluate threat model and regulatory requirements.

Alternatives to consider

Postman

Market-leading, feature-rich, cloud-first with advanced mocking and monitoring. Choose if team already invested in Postman ecosystem or needs enterprise features; trade: proprietary, SaaS-centric, higher cost.

Insomnia

Similar feature set, lightweight, supports REST/GraphQL/gRPC. Choose if seeking another open-source alternative; trade: smaller community, less frequent releases, less team collaboration feature maturity.

curl + shell scripting / Bruno

Minimal approach (curl) for automation, or Bruno (newer, git-friendly alternative). Choose for bare-metal CI/CD or developers preferring version control over UI; trade: steeper learning curve, no GUI, reduced discoverability.

hoppscotch FAQ

Can I use Hoppscotch offline?

Yes. PWA architecture with Service Workers enables offline support. Data syncs when connectivity returns. Note: real API requests still require network; offline mode supports request drafting and local collection browsing.

Is Hoppscotch suitable for enterprises?

Yes, with caveats. Self-hosted deployment supports on-premise/air-gapped setups. Team features, RBAC, and admin dashboard exist. SSO noted as Enterprise Edition feature; clarify what features require separate licensing before adoption.

How do I integrate Hoppscotch into CI/CD?

Use Hoppscotch CLI (included in monorepo). Export collections, run tests via CLI, parse results in pipeline. Validate CLI performance and collection export workflow in your pipeline before production use.

What are the risks of using the official Hoppscotch proxy?

Proxy centralizes HTTP/CORS traffic through Hoppscotch's server. Review their privacy policy (linked in docs). For sensitive APIs, deploy proxyscotch (open-source proxy) self-hosted or use your own CORS proxy.
