## 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

## Uxia

Uxia exists to close the gap between how fast product teams now ship and how slowly traditional user research runs. Modern teams prototype and release multiple times a day, yet usability testing is still expensive and slow enough to be skipped — and that skipped feedback turns into rework later. Uxia's answer is a continuous research layer that combines AI-generated synthetic testers with real human participants inside one platform.

Workflow starts with audience building. Teams spin up AI participants from binary filters — demographics, country, tech literacy, and psychological profiles drawn from public databases and OCEAN-style modelling — and then enrich them with their own personas, prior interviews, and product vocabulary. When additional rigour is needed, human testers can be recruited from partner panels covering 14M+ participants worldwide, or teams can bring their own users.

From there, Uxia supports unmoderated usability tests on Figma prototypes, AI-built apps, static designs, and live websites — including flows that sit behind a login — as well as accessibility checks, card sorting, surveys, and AI-moderated interviews where the moderator builds its own discussion guide and decides when to dig deeper. Everything lands in one unified report, and teams can chat with their research data to surface deeper patterns. Gartner recognised Uxia as a Diamond Startup in the Synthetic Population and Behavioral Simulation space, and the company reports more than 900 product teams using the platform.

**Pricing & Plans:** Uxia offers a free start so teams can collect insights in minutes with AI participants, plus tiered research plans and a free trial. Larger initiatives, expanded human panel access, and enterprise UX or market research programmes are quoted through a sales conversation — book a demo to get a custom price.

- **AI testers built from real audience data:** Define demographic, geographic, and psychological criteria using 15+ filters backed by public databases, then enrich AI testers with your own personas, past interviews, and terminology.
- **Human tester recruitment:** Recruit from 14M+ human participants or invite your own users to run unmoderated usability tests and interviews when you want to validate synthetic findings.
- **AI-moderated interviews at scale:** The AI moderator builds discussion guides, decides follow-up questions, runs hundreds of sessions at once, and reports in 90+ languages.
- **Multi-method testing in one flow:** Combine tasks, surveys, card sorting, and accessibility checks into one flow, testing Figma prototypes, AI-built apps, static designs, or live websites that require logins.
- **Unified UX research reporting:** See usability heatmaps, task success rates, think-aloud sessions, and transcripts, then merge synthetic and human results into one report that executives can act on.

**Strengths:** Synthetic testers return usability insights in roughly 10-15 minutes; Human and AI testing live in one platform and merge into a single report; Supports prototypes, live websites with logins, and accessibility checks; AI-moderated interviews scale to hundreds of sessions in 90+ languages

**Limitations:** Enterprise and custom research pricing requires a sales conversation; Synthetic tester accuracy depends on how well you supply persona data; Human panel recruitment is routed through partner networks, so panel composition can vary; Full value comes from running testing continuously, which needs process buy-in from design and PM teams
