## Kropply

Kropply fits into an existing developer loop rather than replacing it. You keep editing and saving TypeScript files as usual, and whenever a test fails or a runtime error surfaces, the extension steps in with suggestions for how to correct the unit-level bug. It is designed for teams and individuals who already write tests and want the AI to do something genuinely useful with them, instead of asking for more prompting overhead.

The extension's guiding principle is that your code, comments, documentation and tests already describe what you are trying to achieve. Rather than prompting an assistant in a chat window, you let Kropply read that context and propose fixes. It is aimed at the unglamorous but frequent problems—runtime errors and small logic bugs—that interrupt a developer's flow.

Kropply is distributed primarily as a free extension on the Visual Studio Code Marketplace and is aimed at TypeScript developers using Jest. Because it works from test expectations, projects with good test coverage tend to get the most value. Note: during our check the product's own marketing website was not reachable, so refer to the Marketplace listing and its linked getting-started documentation for the latest details.

**Pricing & Plans:** Free. Kropply is listed as FREE on the Visual Studio Code Marketplace, which is its primary distribution channel. No paid tier is indicated on the listing; contact the team directly for any commercial arrangements.

- **AI autocorrect for runtime errors:** Suggests fixes for unit-level bugs and runtime errors as you work, rather than making you hunt through logs manually.
- **Runs in the background on save:** Triggers automatically whenever you save a TypeScript file (.ts, .tsx), so it fits a normal edit-save-test loop with minimal setup.
- **Test-driven fix generation:** Uses the expected output from your tests to understand how the code should behave, turning your existing tests into a guide for the AI.
- **Prompt-free workflow:** Suggests code and action points without requiring you to craft prompts, on the premise that your code and comments convey intent.

**Strengths:** Reduces the friction of fixing runtime and unit-level errors; Works with your existing tests instead of demanding elaborate prompts; Triggers automatically on save, so it needs little workflow change; Free to install and try from the VS Code Marketplace

**Limitations:** Currently focused on TypeScript projects with the Jest testing framework, so it won't help every language or setup; Primary distribution is the VS Code Marketplace extension rather than a full standalone service; Its main website was unreachable during our check, so docs and contact routes may be affected; Relies on test expectations being present to guide fixes, so untested code gets less benefit

## Pi Coding Agent

Pi is a terminal-based coding agent built around one idea: the harness should adapt to your workflow, not the other way around. It keeps a deliberately small system prompt and core, which makes it token-efficient and lets you control exactly what lands in the context window. Instructions come from AGENTS.md files, a per-project SYSTEM.md, on-demand skills, reusable prompt templates and extensions that can inject context before each turn.

Instead of shipping every feature, Pi exposes primitives. Sub-agents, plan mode, permission gates, path protection, sandboxing, SSH execution, custom editors and status bars can all be built with extensions, asked for in natural language, or installed from third-party packages on npm and git. MCP is built in, and Codemode lets agents compose tool calls inside a JavaScript sandbox. Session history is stored as a tree, so you can rewind to any earlier message, branch from there, and export or share the whole thing.

Pi runs in four modes: the full interactive TUI, print/JSON mode for scripts and pipelines, an RPC protocol over stdin/stdout for non-Node integrations, and an SDK for embedding it in your own apps. It connects to 15+ providers including Anthropic, OpenAI, Google, Azure, Bedrock, Mistral, Groq, Cerebras, xAI, Hugging Face, OpenRouter and local Ollama, and you can switch models mid-session with a keystroke. Models, packages, changelog and docs all live on the project site.

**Pricing & Plans:** Free and open source (MIT). You only pay your chosen model or API provider; no subscription is required for the agent itself.

- **Extensible harness:** Build commands, tools, keyboard shortcuts, overlays, sub-agents or permission gates as TypeScript extensions, or install them as packages from npm and git.
- **Context engineering:** AGENTS.md instructions, per-project SYSTEM.md, on-demand skills, prompt templates and customizable compaction keep the context window under your control.
- **Multi-provider models:** Connect 15+ providers from Anthropic and OpenAI to Bedrock, Groq, OpenRouter and local Ollama, then switch models mid-session.
- **Four run modes:** Interactive TUI, print/JSON for scripting, an RPC protocol for non-Node hosts, and an SDK for embedding the agent.
- **Tree-structured history:** Rewind to any previous message, branch from it, and export to HTML or share the session via a gist URL.

**Strengths:** Open source under MIT with a minimal, readable core; Highly extensible: add or install the features other agents hard-code; Token-efficient thanks to a small system prompt; Broad model support with mid-session switching and local Ollama options

**Limitations:** Deliberately ships without sub-agents, plan mode or permission popups by default; You may need to build or install extensions to get a full-featured experience; Terminal-centric UI has a learning curve if you expect a GUI
