## Blume

Blume is a local desktop application for developers who work with coding agents. Its site describes the core problem it solves: as agents produce more code, the hard part becomes keeping their work visible, trustworthy, and reviewable. Today that means piecing together terminals, chat logs, and branches, and trusting that an agent saying "done" really means the change works.

Blume's answer is the delivery model. Agents plan, build, and test, and Blume keeps the record. Each session becomes a delivery that includes the original brief, the task tree, the agent runs, the code revision, the tests, and screenshots – intact from the first instruction to the merged commit. When a verified revision is ready, you step in as the human and approve exactly what you ship. The app follows every session and works with Codex, Claude Code, Grok Bot, and other harnesses through a plugin, so each conversation connects on its own.

The product is positioned around three practical challenges: visibility across multiple agents, trust in an agent's claims, and the review load on limited human attention. Blume addresses them by bringing work and evidence together for one clear decision, and by converting acceptance criteria into tests that rerun before review. It is a download-first, local desktop tool aimed at individual developers and teams running agentic coding workflows.

**Pricing & Plans:** Blume is distributed as a free download to get started; the site does not publish a public price list, so current plan details should be confirmed with the vendor.

- **Delivery-based tracking:** Every agent session becomes a delivery with its brief, task tree, agent runs, code revision, tests, and screenshots kept intact from first instruction to merge.
- **Evidence-based review:** Each claim an agent makes is pinned to a specific task, delivery, and commit, so you review proof rather than a status message.
- **Multi-agent visibility:** See what every agent is doing and what work remains before you ship, instead of piecing together terminals and chat logs.
- **Agent plugin integration:** Install a plugin into Codex, Claude Code, or another harness, and each conversation connects to Blume on its own.
- **Test-first quality flow:** Acceptance criteria are turned into tests before review, and suites rerun before each review so fixes are verified.

**Strengths:** Turns scattered agent sessions into one reviewable delivery with brief, tests, and screenshots; Evidence is pinned to a specific commit, so approval is based on proof rather than a "done" message; Works with major agent harnesses like Codex and Claude Code through a plugin; Runs as a local desktop app, keeping your code and sessions on your machine

## 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
