## 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

## Select Star

Select Star attacks a problem every maturing data team recognizes: the data exists, but nobody is sure which version of it is authoritative or who to ask. The platform connects to your warehouses, ELT/ETL pipelines, and BI tools, reads their metadata and query history, and automatically produces documentation, lineage, and usage statistics. Instead of a manually maintained spreadsheet of tables, you get a living catalog that reflects what is actually being queried, including which tables have quietly gone unused.

Lineage is the centerpiece. Select Star traces data down to the column level and across platforms, so you can answer concrete questions: if this field changes, which dashboards break, and who gets affected? The same graph is used for governance — PII tags can be propagated to downstream columns so sensitive data is visible wherever it flows, which matters for audits and compliance work. A data portal layer sits on top, letting anyone search for certified datasets, read descriptions and tags, and record discussions against a dataset so answers stay attached to the data.

More recently Select Star has leaned into AI readiness. Reporting is that it is now part of Snowflake, and the product exposes metadata, lineage, and generated semantic models to LLMs and agents through interfaces such as an MCP server, aiming to be the context layer that makes AI answers trustworthy rather than plausible. Pricing is quote-based rather than published, and is typically sized against the number of connected sources, data volume, and required seats, so evaluation starts with a sales conversation.

**Pricing & Plans:** Quote-based enterprise pricing; Select Star does not publish public list prices. Cost depends on the scale of your environment — connected data sources, data volume, and the seats or capabilities you need — so evaluation typically starts with contacting sales. There is a free Chrome extension, and the SEO/AI discovery scoop of legacy listings should not be read as a price.

- **Automated data catalog and documentation:** Select Star automatically indexes metadata across warehouses, pipelines, and BI tools, generating documentation so analysts spend less time hunting for the right dataset.
- **Column-level lineage and impact analysis:** Cross-platform, column-level lineage shows where data originates, who is using it, and which dashboards are built on top of it, so impact is visible before you change anything.
- **Data portal for shared knowledge:** A shared data portal where teams tag and describe assets, ask questions, and browse previous discussions attached to each dataset, turning tribal knowledge into searchable documentation.
- **Governance, PII tracking, and security:** Use lineage and tagging to locate exactly where sensitive fields travel, propagate PII tags downstream, and support SOC 2-aligned security, confidentiality, and availability practices.
- **AI-ready metadata for LLMs and agents:** Reverse-engineered semantic models and an MCP server expose metadata, lineage, and semantics to LLMs and agents, giving AI tools the context they need for reliable answers.

**Strengths:** Automated cataloging removes the manual work of maintaining a data inventory; Column-level, cross-platform lineage makes change impact analysis concrete; PII tag propagation and SOC 2-aligned controls support governance and audits; A shared portal turns scattered tribal knowledge into searchable documentation

**Limitations:** Enterprise-focused pricing means no transparent public price list and a longer procurement cycle; Value depends heavily on how many data sources and BI tools you connect; a small stack gains less; Heavier governance and tagging features can require ongoing admin effort to keep metadata useful; Being acquired by Snowflake may raise questions about roadmap focus for non-Snowflake-centric stacks
