Temporal
Durable workflow execution platform that ensures code runs to completion despite failures, timeouts, or restarts. Workflows are expressed as code (Python/Go/Java/TypeScript) with automatic state persistence. Temporal Cloud offers a fully managed service with REST API.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
mTLS for worker-server communication. API keys for Temporal Cloud management. Namespace-level isolation. Self-hosted Temporal requires manual TLS configuration. SOC2 Type II for Temporal Cloud.
⚡ Reliability
Best When
An agent orchestrates long-running, multi-step processes that must be resilient to failures, require compensating actions, or pause for external signals.
Avoid When
Your workflows are simple, short-lived background jobs where Temporal's durability guarantees are overkill and the operational complexity is not justified.
Use Cases
- • Long-running agent workflows that must survive process restarts and infrastructure failures
- • Multi-step saga patterns with compensating transactions for distributed consistency
- • Human-in-the-loop workflows that pause for days/weeks awaiting signals
- • Orchestrating complex AI pipelines with retry, timeout, and branching logic
- • Replacing unreliable cron jobs with durable scheduled workflows
Not For
- • Simple fire-and-forget background jobs (BullMQ or Celery are simpler)
- • Teams without engineers comfortable with Temporal's workflow/activity programming model
- • Low-latency real-time workloads (Temporal adds orchestration overhead)
- • Non-supported languages outside of official SDK languages
Interface
Authentication
Temporal Cloud uses API keys or mTLS client certificates. Self-hosted Temporal supports custom authorization plugins. Temporal Cloud REST API uses Bearer token auth. Namespace-level access scoping available on Cloud.
Pricing
Self-hosted OSS is fully free but requires running Temporal server, database (PostgreSQL/Cassandra), and Elasticsearch. Temporal Cloud eliminates all infrastructure management with pay-per-action pricing.
Agent Metadata
Known Gotchas
- ⚠ Workflow code must be deterministic — non-deterministic code (random, time.now(), direct API calls) must be wrapped in activities
- ⚠ Workflow history size limit (~50K events) — very long-running workflows need Continue-As-New pattern to reset history
- ⚠ Temporal's programming model has a learning curve — agents generating workflow code must understand determinism constraints
- ⚠ gRPC is the primary protocol — REST API is newer and has more limited coverage than gRPC
- ⚠ Self-hosted deployment requires significant infrastructure (server, DB, Elasticsearch for visibility)
- ⚠ SDK versions across languages are not always feature-equivalent — check SDK changelog before relying on a feature
- ⚠ Signals and queries are different mechanisms — agents must choose the right primitive for external interaction
