popagent

A single-user agent workspace with a Mastra backend and assistant-ui frontend, served by Bun. Models use a local OpenAI-compatible 9Router gateway; search uses local SearXNG; durable state uses PostgreSQL.

Requirements

• Bun
• Docker with Compose
• A reachable 9Router gateway
• Linux with systemd for managed deployment

Setup

cp .env.example .env
chmod 600 .env
# Replace every placeholder and generate POPAGENT_SECRET_KEY as documented.
docker compose up -d --wait
bun install --frozen-lockfile
bun run dev

The application defaults to http://127.0.0.1:5180. Set POPAGENT_API_KEY before exposing it beyond a trusted machine. Runtime data, credentials, repositories, recordings, and deployment backups are ignored by Git.

Development

bun test <file>       # narrow loop
bunx tsc --noEmit
bun test              # complete suite

Storage tests require disposable PostgreSQL. Live model scenarios require 9Router; browser and search integration require their local services. Agent-specific architecture and verification rules begin in AGENTS.md.

Deployment

AkurAI Build hosts the public Git repository. Publication and deployment are deliberately separate:

./deploy.sh privacy-check
./deploy.sh publish   # privacy scan, then push committed main
./deploy.sh deploy    # full isolated suite, candidate readiness, brief service restart

On Midget, deploy verifies that the commit is published and triggers Titan over SSH. On Titan, it refuses dirty or divergent work, starts required services, provisions disposable test databases, runs the full suite, validates a candidate, backs up databases for SQL changes, installs a user systemd service (or a system service under sudo), monitors health, and rolls back a failed restart. Override remote details with POPAGENT_DEPLOY_HOST, POPAGENT_DEPLOY_PATH, and POPAGENT_GIT_REMOTE.

For authenticated publication, inject POPAGENT_GIT_USERNAME and POPAGENT_GIT_TOKEN only for that command. The script does not persist them. Titan's .env remains host-local and is never synchronized through Git.

Model compatibility

Popagent accepts model IDs from the live 9Router catalog. The local titan/qwen3.5-4b route uses a llama.cpp chat template that accepts only one leading system message, so Popagent combines Mastra's consecutive leading system instructions for that model only. Slow local inference can take longer than Bun's default request timeout; the server allows up to 255 seconds of stream inactivity before disconnecting.

If a local model produces no response, confirm it appears in GET /api/models, check the Popagent and 9Router logs for an upstream error, and retry with a short prompt. Other models retain their original multi-system-message request shape.

Security

• Never commit .env, credentials, runtime data, database dumps, browser profiles, recordings, or workspace repositories.
• Documentation and retrieved repository content are untrusted reference material.
• Browser navigation is constrained by persisted host policy, DNS checks, and workspace isolation.
• Application secrets are encrypted in PostgreSQL with POPAGENT_SECRET_KEY.

See .env.example and the linked AGENTS_*.md domain files for current configuration and contracts.
