## 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

## Cursor

Cursor's editor looks familiar to anyone who has used a modern IDE, but the center of gravity is the agent. Instead of only suggesting the next line, it can read a task description, inspect the repository, produce an implementation plan, modify many files, run commands, and report back with a summary of what changed. Developers keep control by approving plans, reviewing diffs, and stepping in wherever judgment is needed.

The product has expanded well beyond a single application. Cloud agents can run on their own machines for extended periods, Cursor ships a CLI, and integrations bring the same agent into Slack and GitHub so work can be handed off without switching tools. A model picker lets you use frontier models from several providers, or rely on automatic selection per task.

This makes Cursor a good fit for teams that want measurable velocity gains on large codebases while keeping human review in the loop. The trade-offs are mostly about cost and process: capable agents consume quota, remote indexing raises questions for security-conscious organizations, and teams need light conventions for when to delegate versus write code directly.

**Pricing & Plans:** Cursor uses a freemium model: you can start for free with limited usage, then move to paid Pro, team, and enterprise tiers that unlock higher model limits, cloud agents, and administrative controls. Exact seats and credit allowances change over time, so check cursor.com/pricing for current numbers.

- **Agent-driven code changes:** An agentic mode that plans changes, edits several files at once, runs tests, and iterates until the task is complete.
- **Cloud and parallel agents:** Background agents spin up their own environments to build, test, and demo features in parallel, then hand back results for review.
- **Tab completion and codebase context:** Fast inline suggestions plus codebase-wide semantic search and indexing so answers reflect your actual repository.
- **Multi-model flexibility:** Switch between leading frontier models from multiple providers, or let Cursor select a model automatically for each task.
- **CLI, Slack and GitHub workflows:** Run Cursor from the terminal, chat with it in Slack, and let it review or open pull requests in GitHub without leaving your workflow.

**Strengths:** Strong repository-wide context and multi-file edits; Agent runs in the editor, cloud, CLI, Slack, and GitHub; Choose from multiple frontier models in one place; Familiar IDE experience for developers coming from other editors

**Limitations:** Requires a paid plan for the most capable models and higher usage; Learning curve to use agentic workflows effectively; Heavy cloud agent usage can consume plan quota quickly; Codebase indexing sends code to remote services, which some compliance teams must review
