- Features - All capabilities, architecture, packages31
- Automation rule engine - Match a trigger. Run a governed action. Every firing on the audit chain.
- Issues: failure fingerprinting - The same bug across every run collapses into one issue.
- Durable bulk retry - Retry a thousand failures once, and only once.
- Rolling upgrades - Upgrade the brain first. Upgrade the agents when you are ready.
- Agent durability - The agent buffers locally and never guesses about someone else's data.
- Scheduler reliability - Know when a schedule should have fired and did not.
- Unified action surface - One button set. Every engine.
- Stuck-task reconciliation - Tasks started forever. Fixed, automatically.
- Historical trends - Success rate, failure rate, throughput over time.
- Visual task DAG - See your canvas: chains, groups, chords.
- Notification providers - Seven native channels. Plug into the stack you already use.
- Severity-aware subscriptions - Page on critical. Email on warning. Drop info into a Slack channel.
- Cooldown and mute - One bad deploy posts once. Not three hundred times.
- MFA with TOTP, recovery codes, and trusted devices - RFC 6238 TOTP, single-use recovery codes, per-device 30-day trust cookie. WebAuthn deferred; SMS / email second factors never (NIST-deprecated for AAL2).
- RBAC built-in - Four roles. Every endpoint gated. UI mirrors server.
- Multi-user invitations - Mint a link. Email it automatically. Accept in one click.
- Password reset flow - Industry-standard, timing-safe, single-use.
- Secure-by-default redaction - Secrets never leave the agent.
- HMAC-chained audit log - Tamper-evident. Even against DBAs.
- Grafana templates - Five drop-in Grafana dashboards keyed to z4j's metric names.
- Live Activity Feed - Cross-project timeline of every privileged action. Polls every 5 seconds.
- Audit webhook forwarding - Mirror every audit row to your SIEM. HMAC-signed.
- Optional OpenTelemetry export - OTLP traces to Honeycomb, Tempo, Jaeger, or any OTel collector.
- Optional Sentry integration - Ship brain crashes to Sentry with credentials redacted in-process.
- Defense-in-depth rate limits - No brute-force vectors on public endpoints.
- Safe worker restart - Universal restart, zero shell execution.
- Pip + SQLite - pip install z4j, then z4j serve. Zero containers, zero infra.
- Docker on x86 / AMD64 - Standard cloud VMs. Native, not emulated.
- Docker on ARM64 - Apple Silicon. Raspberry Pi. AWS Graviton. Native, not emulated.
- Real-time dashboard - Live task events. Live worker state.
- Dynamic scheduler - Edit schedules from the dashboard. Drives every engine.
- Engines - Python task-queue engines and action matrix6
- Celery - The industry standard, covered end-to-end.
- RQ - Lightweight Redis queue, fully instrumented.
- Dramatiq - Middleware-driven Dramatiq observability.
- Huey - Lightweight Redis/SQLite queue, first-class.
- arq - Async Redis queue for FastAPI-era Python.
- taskiq - Broker-agnostic async task framework.
- Frameworks - Framework adapters3
- Django - Django AppConfig integration, zero boilerplate.
- Flask - Flask extension pattern. One line to install.
- FastAPI - Lifespan-hook integration for async stacks.
- Schedulers - Scheduler adapters for every engine7
- z4j-scheduler - Our own scheduler. Engine-agnostic, highly available, and safe to migrate onto.
- Celery Beat - Full CRUD for Celery's canonical scheduler.
- rq-scheduler - RQ's optional scheduler, wired to the dashboard.
- APScheduler - Engine-agnostic scheduler. Pair with anything.
- Huey @periodic_task - Read-only surface for Huey's decorator schedules.
- arq cron_jobs - Read-only surface for arq's WorkerSettings.cron_jobs.
- taskiq scheduler - Wraps LabelScheduleSource + custom sources.
- Install - Deployment paths and TLS guide4
- Pip (SQLite) - Pure Python. No container runtime required.
- Docker (SQLite) - One container. SQLite bundled in the image. No env vars required.
- Docker (Postgres) - Same image, external Postgres. Horizontal-scale ready.
- TLS setup - Reverse-proxy and certificate configuration
- Compare - z4j vs. other dashboards3
- Flower - The classic Celery viewer. Built in 2011.
- RQ Dashboard - The simple web view for RQ.
