## Aspen — Free API Testing for macOS

Aspen is a desktop API client designed specifically for macOS and specifically for REST APIs. Rather than trying to cover GraphQL, gRPC, and every other protocol, it narrows its focus so that setting up and running a request takes seconds. Everything executes locally on your machine — there is no login and no data saved to a server, which the developers frame as a zero-trust approach for teams that cannot send request and response payloads to a third party.

The AI assistant, Alfred, is the feature that separates Aspen from a plain request runner. Given the responses from a working call, it can draft the corresponding data models, produce an OpenAPI specification, and generate integration code, cutting the manual step between "the endpoint works" and "the app can call it." Aspen is developed by Treblle, an API lifecycle platform, so the tool plugs into a broader ecosystem of observability, analytics, governance, and auto-generated API documentation products.

A newer Collections feature adds collaboration to what was previously a solo tool: you can organise, import, export, and share API requests to reuse them across a team, with import from Postman and export of your own collections. Aspen itself is free to download and use, making it an easy replacement for paid clients when your work is centred on REST endpoints on a Mac.

**Pricing & Plans:** Free. Aspen is a free macOS download with no account requirement; it is developed by Treblle, which also offers paid API lifecycle products alongside a free tier.

- **Local, login-free testing:** Run API requests inside a native Mac app without creating an account, with all operations performed on your machine.
- **AI companion Alfred:** Generate data models, OpenAPI specifications, and integration code from your API responses to speed up development.
- **REST-first workflow:** The tool is optimised for REST APIs, so requests return results in under a second without protocol overhead.
- **Aspen Collections:** Organise, import, export, and share API requests, with Postman import so existing collections come across easily.
- **Part of the Treblle ecosystem:** Connect to API observability, analytics, governance, and auto-generated documentation from the same vendor.

**Strengths:** Completely free with no login or account setup; Native macOS performance keeps response times under a second; Alfred turns raw responses into models, specs, and code; No data stored externally, which suits security-sensitive work

**Limitations:** macOS only — there is no Windows or Linux build; Focused on REST, so GraphQL and other protocols are out of scope; No built-in cloud sync because nothing leaves your machine

## Qoder

Qoder is an agentic coding platform built for real software engineering rather than isolated code snippets. Its family of products covers an AI-native desktop IDE, plugins for VS Code and JetBrains, a CLI for terminal-first developers, and a mobile app for monitoring agents on the go. The pitch is simple: bring an idea, and Qoder's agents plan, edit across files, run checks and hand back working code.

The platform leans heavily on context. Qoder indexes and reasons over your entire repository so that suggestions, refactors and new features respect existing architecture, conventions and dependencies. Developers can work in different modes — inline completion for small edits, conversational chat for collaborative changes, and an autonomous agent mode for delegating larger tasks with approval gates. Spec-driven development and a knowledge/base-context layer help keep long-running tasks aligned with the actual project.

Qoder is also extensible. An Agent SDK lets teams embed Qoder's agent capabilities into their own products, while Cloud Agents APIs support building productised, server-side agent flows. With generous free access for individuals and paid tiers for teams, Qoder targets the growing market of developers who want agentic help without abandoning their existing tools or editor.

**Pricing & Plans:** Freemium with a free plan and a free trial for individuals; paid Pro and team/business tiers unlock higher usage limits, advanced agent models and enterprise features. Exact prices are listed on Qoder's pricing page.

- **Agentic IDE:** An AI-native desktop IDE where agents read the codebase, plan multi-step work and complete tasks across many files.
- **Coding agent modes:** Switch between autocomplete for quick edits, chat for collaborative coding, and an autonomous agent for delegated tasks with approval controls.
- **Codebase awareness:** Repository-wide indexing and context engineering keep changes aligned with your architecture, style and dependencies.
- **Works where you work:** Plugins for VS Code and JetBrains, a terminal CLI, and a mobile app for monitoring and approving agents remotely.
- **Agent SDK and Cloud Agents:** Embed Qoder's agent capabilities into your own products via the Agent SDK, or build managed agent services with Cloud Agents APIs.

**Strengths:** Full product family: IDE, plugins, CLI and mobile in one agentic platform; Strong codebase context and spec-driven workflows for real projects; Agent SDK and Cloud Agents APIs for building your own agent products; Free tier makes it easy to evaluate before committing

**Limitations:** Agentic coding needs careful review of diffs before merging; Advanced limits and enterprise features require paid plans; Full value depends on adopting Qoder's IDE or plugins into your workflow
