Replacing Postman in 2026
In short: for a lightweight local client, look at Bruno, Yaak, or Tetiva (30 MB, no account, no telemetry, open beta); for browser access across a team, Hoppscotch; for maturity and plugins, Insomnia. Below: the criteria that matter and how these five clients differ in practice.
Postman is no longer just an app for sending HTTP requests. It is a broad API platform with design tools, documentation, monitors, team workspaces, and agent features. That scope is useful when a company wants one system for the API lifecycle. It can feel like more than necessary when a developer mainly needs to inspect and test endpoints.
This is not a winner-takes-all ranking. Each option below makes a different tradeoff. Pricing and plan limits change, so confirm them before purchasing. Application size also varies by operating system and release. If a vendor does not publish a stable figure, a random installer size is not a fair comparison.
What to compare before switching
A clean interface matters, but these criteria tend to decide whether a client survives daily use:
- Size and startup. Measure installed size and a cold launch after reboot. A second launch from the filesystem cache is a different result.
- Protocols. REST is the baseline. gRPC, GraphQL, WebSocket, SSE, and Socket.IO support can remove the need for separate utilities.
- Privacy. Find out where collections and secrets live, whether an account is required, and what analytics the app sends.
- Sync. Cloud collaboration favors immediacy; Git favors reviewable text changes; self-hosting favors infrastructure control.
- Price. Check commercial-use terms, collaborator limits, administration features, and CLI access—not only the individual free tier.
Insomnia: a mature client with storage choices
Insomnia is a good fit for teams that want an established desktop client and a broad feature set. It handles REST, GraphQL, gRPC, WebSocket, Socket.IO, SSE, and SOAP. It can import Postman and OpenAPI data, while Inso CLI brings collection tests into CI.
Its clearest advantage is storage flexibility. Projects can stay local, use Git Sync, or use Insomnia’s cloud. The local Scratch Pad works without signing in. Insomnia does collect analytics data; its privacy policy lists services including Segment, Sentry, and Google Analytics. That is not the same as sending every request to a vendor, but companies with strict egress rules should review the documented data flow.
The free Essentials plan includes local and cloud projects plus Git Sync with collaboration limits. At publication time, Pro is $12 per user per month and Enterprise is $45. Insomnia makes sense when API design, OpenAPI tooling, CLI automation, and storage options matter more than having the smallest desktop package.
Bruno: collections designed for Git
Bruno treats the filesystem and Git as the collaboration layer. Collections are text files, so teams can review request changes in pull requests, branch them with application code, and move them without depending on a hosted collection database. Basic local use does not require an account.
The client supports HTTP, GraphQL, and gRPC; project documentation also lists WebSocket, Socket.IO, and MQTT. Core client features are available in the open-source edition. Paid plans add a more extensive Git interface, integrations, and organization controls. Current annual-billing prices are $6 per user per month for Pro and $11 for Ultimate.
Bruno is especially practical when Git already defines how a team collaborates. The tradeoff is equally clear: concurrent edits are resolved through branches, diffs, and merge conflicts, not a cloud document with live presence.
Yaak: local data and a focused desktop UI
Yaak is an open-source, local-first client built with Tauri. It supports HTTP, GraphQL, gRPC, WebSocket, and SSE. Workspaces can be stored as plain files and synchronized through Git; there is no Yaak cloud storing project data.
The project explicitly advertises zero telemetry. Requests and history remain on the device, and secrets can be encrypted. The source is MIT-licensed, but the official signed binaries are free only for personal use. Professional use currently costs $79 per year for an individual or $149 per user per year for a business. Its fallback license allows continued use of the last eligible version after a subscription ends.
Yaak is a strong candidate when you want a restrained interface, local storage, and Git collaboration, and its binary licensing model works for your organization.
Hoppscotch: web access with a self-hosting path
Hoppscotch starts in the browser, with no installation required. Desktop and CLI clients are also available. Its documented platforms cover REST, GraphQL, WebSocket, SSE, and Socket.IO. Teams adopting it for a gRPC-heavy workload should verify current support for their exact flow before committing.
The distinguishing option is self-hosting the platform. A company can provide a shared web interface and team workspaces while keeping deployment under its control. Hoppscotch Cloud has a free plan with unlimited workspaces, collections, and requests. The Organization plan is currently $6 per user per month when billed annually; check the current comparison for self-hosted enterprise features.
Browser access removes desktop rollout work, but browser security restrictions can complicate calls to local services. Hoppscotch addresses those cases with an agent and desktop app. It is a sensible choice when access by URL and an on-premises deployment matter more than a purely local file workflow.
A compact desktop client in open beta
Tetiva is an open-source desktop API client for HTTP, gRPC, GraphQL, and WebSocket. The current app is about 30 MB and the project reports a cold start below 500 ms. Those are project figures, not a cross-product benchmark on identical hardware.
It imports Postman collections, sends no telemetry, and offers self-hosted sync. Request scripts run inside a Goja sandbox. A built-in MCP server can expose saved collections to AI agents. The product is still in open beta, however, so evaluate import fidelity, the protocol paths you rely on, and upgrade behavior before making it part of a critical workflow. The desktop beta is free today; future commercial terms should not be assumed before they are announced.
A practical shortlist
Choose Insomnia for mature design features and multiple storage models. Choose Bruno when collections should be ordinary Git-reviewed files. Consider Yaak for a private local workflow and a focused interface. Try Hoppscotch when browser delivery and self-hosting are central requirements. Evaluate the fifth option for its small footprint, protocol mix, and MCP server, while accounting for its beta status.
The best final check is hands-on: import a real collection, go offline, inspect secret handling, run a gRPC stream, and have two teammates edit the same request. A short pilot with your own API reveals more than a long feature matrix.
