Temporal
Also known as: Temporal.io, Temporal Cloud, Temporal Technologies
Durable execution platform whose event history replay lets long running microservice and AI agent workflows resume exactly where they failed, available as open source self hosted software or managed multi region cloud.
Temporal is the incumbent of durable execution, and increasingly the orchestration backend under production AI agents. Founded in 2019 by Samar Abbas and Maxim Fateev, the co creators of Uber's Cadence engine with prior work on Amazon Simple Workflow Service and Microsoft's Durable Task Framework, it has raised roughly $650 million across six rounds including a $300 million Series D in February 2026 led by Andreessen Horowitz at a $5 billion valuation. Snap, Netflix, HashiCorp, OpenAI, ADP and Block run on it, across a reported 9.1 trillion lifetime action executions.
The model is workflow as code. You write ordinary application logic in one of seven language SDKs, and Temporal records every step into an event history and replays that state after a failure, so a multi step agent plan or a payment saga resumes exactly where it stopped rather than restarting. Around that sit Activities for external calls, Signals and Updates for injecting input into a running workflow, Timers and Schedules, and Activity Heartbeats for long running work. Event histories run to 200,000 events with configurable retention.
It is explicitly not an AI product. It is the substrate other agent frameworks run on, and its integration catalogue reflects that: durable execution for the OpenAI Agents SDK, type safe agents through Pydantic AI, AWS Strands Agents orchestration, durable Spring AI tool calls, plus observability routes into Prometheus, Grafana and Parseable and governance guardrails through OpenBox. Its stated product direction around serverless workers and agent orchestration points the same way.
Deployment is its strongest structural advantage. The community edition is open source and self hostable, running a Go server with Cassandra or PostgreSQL for persistence and Elasticsearch for visibility queries, which is the route organisations take under strict data residency requirements. Temporal Cloud is the managed alternative, with a high availability tier offering multi region replication, a 99.99 percent uptime commitment, sub one minute recovery point and twenty minute recovery time objectives. The trade off is operational weight: self hosting is a real infrastructure commitment and the learning curve is the most cited objection to adopting it.

In practice
Your research agent runs for three days across fifty documents and the server restarts mid task. Event history replay resumes from the last recorded step rather than repeating API calls and duplicating writes.
You already use the OpenAI Agents SDK, Pydantic AI or AWS Strands and want the agent to survive failures without rewriting it. Temporal has documented durable execution integrations for each rather than asking you to adopt its own agent framework.
Data residency rules prevent using a managed orchestration service. The community edition self hosts on your own infrastructure, which is the documented reason organisations choose it over Temporal Cloud.

| Knowledge Grounding & RAGNo retrieval, vector store or knowledge grounding capability. Temporal is explicitly not an AI product; it is the orchestration backend, and grounding belongs to the agent framework running on top of it. 2026-08-05 | Unable to verify |
| Human Oversight & GuardrailsSignals, Updates and Timers let a running workflow pause and accept external human input, which is the same primitive class Inngest markets as human in the loop, but Temporal does not frame or package it that way and governance guardrails for AI workflows arrive through a third party integration, OpenBox, rather than natively. 2026-08-05 | Partial |
| Security, Identity & GovernanceRE GRADED 2026-08-05 from P to F after retrieving first party security documentation. Temporal Cloud is SOC 2 Type 2 certified and compliant with GDPR and HIPAA with BAA support, with a trust centre at trust.temporal.io and compliance audits available on request. Controls include annual third party full scope penetration testing, production access gated by SSO with MFA granted just in time and time boxed to eight hours with no shared accounts and full logging, per namespace endpoints and certificates from the customer's own CA, SSO and RBAC for fine grained access, mTLS, and AWS PrivateLink or Google Cloud Private Service Connect to keep workflow traffic off the public internet. A customer hosted Codec Server allows payloads to be encrypted client side so Temporal never sees plaintext, and workers poll outward so Temporal never calls into the customer VPC. IMPORTANT SCOPING: these certifications apply to Temporal Cloud only, NOT to self hosted deployments, and no ISO 27001 certification was found on the vendor's own domain. | Full |
| Observability & AuditabilityEvent history makes every executed step permanently inspectable, Elasticsearch backs visibility queries on self hosted deployments, and documented integrations stream workflow and activity events to Parseable and scrape Cloud metrics into Prometheus and Grafana. The audit trail is a structural property, not a feature. 2026-08-05 | Full |
| Memory & State PersistenceEvent history replay is the definitive implementation of durable state: every step is recorded and state is automatically reconstructed after failure so execution resumes exactly where it stopped, with histories up to 200,000 events and configurable retention. 2026-08-05 | Full |
| Deployment & Data ResidencyThe strongest deployment position in this sweep: fully self hostable open source community edition running a Go server with Cassandra or PostgreSQL and Elasticsearch, explicitly the route for strict data residency requirements, plus a managed cloud whose high availability tier adds multi region replication, a 99.99 percent uptime commitment, sub one minute RPO and twenty minute RTO. 2026-08-05 | Full |
| Prebuilt Agents, Templates & PacksAn integrations catalogue and reference samples exist across seven SDKs, but Temporal ships no prebuilt agents, template gallery or ready to deploy packs; the agent layer is expected to come from OpenAI, Pydantic AI or AWS Strands. 2026-08-05 | Partial |
| Triggers & Channel CoverageWorkflows start on demand or from Schedules, receive Signals and Updates from external systems mid execution, and use Timers for time based continuation, giving event driven, scheduled and externally signalled invocation. 2026-08-05 | Full |
| Model Flexibility & RoutingEntirely model agnostic by design with no model list, routing policy, selection interface or bring your own key concept, since model choice belongs to the agent framework running on top. 2026-08-05 | Unable to verify |
| APIs, SDKs & MCP ExtensibilitySeven language SDK coverage on an open source core, with a documented integrations catalogue and the whole platform addressable as code. Broader language reach than anything else in this sub category. No MCP server is documented. 2026-08-05 | Full |
| Testing, Debugging & OptimizationEvent history makes any execution replayable and inspectable after the fact, which is a genuine debugging surface, but no local development parity tooling, replay test framework or evaluation harness was documented in the material retrieved. Likely an undergrade; re verify against Temporal's testing documentation. 2026-08-05 | Partial |
| Browser & Computer UseNo browser control or computer use capability. Temporal executes developer written workflow and activity code rather than operating interfaces. 2026-08-05 | Unable to verify |

Recent platform changes
Temporal has introduced Projects for Temporal Cloud in Pre-Release. This feature provides a first-class mechanism to organize Temporal Cloud resources, including namespaces and Nexus endpoints.
Bears on: Security / enterprise
View sourcePricing
Free to self host (open source); Temporal Cloud Essentials from about $100 per month, Business from about $500, plus roughly $50 per million Actions
cloud plan fee plus Actions and storage; free if self hosted
What is public
Plan structure, approximate rates and the Action based consumption model are widely documented, and Temporal publishes a pricing page that was not retrieved in this pass.
Billing mechanics
Two entirely different cost models. Self hosting is free of licence cost but carries the infrastructure and operational burden of running the Temporal server with Cassandra or PostgreSQL and Elasticsearch, modelled by third parties at roughly $2,500 to $4,500 a month at moderate scale. Temporal Cloud combines a monthly plan fee with consumption on Actions and on active and retained storage.
Cost watchouts
Actions accumulate per primitive rather than per run, retained event history is billed as storage, and self hosting carries substantial operational cost for Cassandra or PostgreSQL plus Elasticsearch
Variable cost rationale
Actions accrue per primitive rather than per workflow, so agent loops with retries, heartbeats, signals and long lived event histories multiply the count in ways that are hard to forecast, and retained history is separately billed as storage.
Additional watchouts
Independent guidance advises caution for teams that cannot yet estimate Actions or storage, which is precisely the position of anyone with unpredictable agent behaviour. Learning curve and operational weight are the two most cited objections in comparisons against lighter alternatives.
Overage / add-ons
Consumption billed on Actions at roughly $50 per million, plus active and retained storage, on top of the monthly plan fee
Sales call required
Mixed (some tiers require a call)
Free / trial
The community edition is free and open source with no usage limits, and Temporal Cloud offers a free tier described as generous for development

Commercial notes
The Action is the unit that catches agent teams out. A background agent is not one run: starting a workflow, calling tools through activities, retrying failures, recording heartbeats, receiving signals and updates, setting timers and holding event history open all register separately. Comparative modelling puts Temporal Cloud above AWS Step Functions at equivalent volume, with durability rather than unit price as the justification.
Key ambiguities
Sources conflict on the Cloud entry point, quoting both about $100 and about $200 per month, and Temporal changed its Cloud plan structure recently. The open source licence is reported as both MIT and Apache 2.0. Verify both at temporal.io before relying on either.
Missing data
Confirmed current plan names and rates after the recent restructuring, storage rates, and the licence under which the community edition ships.
