Pick by fit, not by which language your team writes
Mastra is TypeScript-only by design. Connic is a managed, language-agnostic platform under a German contract, with first-party Kafka, SQS, Stripe, Postgres, and email connectors in place of glue you'd write inside your framework. Connic data and connic/* inference stay in the EU.
Mastra has real momentum: a $22M Series A led by Spark Capital, a 1.0 release in January 2026, and an Apache 2.0 core TypeScript teams have adopted fast. Mastra fits agents built as TypeScript modules inside a larger web app. Mastra Platform added managed EU regions in July 2026, so procurement now has a documented hosting answer. The remaining distinction is the contract: Mastra's counterparty is a US company.
Connic provides a German company as counterparty and keeps its platform data and connic/* inference in the EU. Traces, judges, guardrails, approvals, A/B testing, and connectors ship as one platform; full-Project residency depends on customer configuration. A Mastra Platform environment can now pin its app server, hosted database, and observability to an EU region. The region cannot be changed after the environment is created, and external providers still need separate configuration.

Observability & Evals
| Feature | Connic | Mastra |
|---|---|---|
| Tracing and run historyMastra has built-in tracing and Studio observability. Connic includes tracing in every paid plan. | Yes | Yes |
| Built-in judges / evalsBoth include evaluations. Mastra supports code-based scorers plus Studio experiments, datasets, and feedback analytics; Connic's judge service is a managed platform primitive. | Yes | Yes |
| Agent memoryBoth include agent memory. Mastra's Gateway allowances are part of its current plan pricing rather than a separate team subscription. | Yes | Yes |
| Guardrails as a platform primitiveConnic gates agent turns at the platform level. Mastra documents sensitive trace redaction and framework-level safeguards, but not the same managed turn gate. | Yes | Partial |
| Human approvals (HITL)Both support human approval. Mastra can suspend an agent for tool approval and resume it after a decision. | Yes | Yes |
| A/B testing with traffic splitsConnic runs statistical A/B tests between agent versions in production. Mastra's public docs do not describe a native production traffic-split router. | Yes | No |

The EU question
Mastra's Apache 2.0 core can run in any EU region you control. Mastra Platform also added managed EU regions in July 2026. An environment pins its app server, hosted database, and observability to the selected region, which cannot be changed after creation.
Agreements run through Kepler Software Inc., a US company. Model providers, webhook senders, and other customer integrations keep their own residency boundaries. Self-hosting remains available when policy requires operating the runtime directly. Read what self-hosting actually costs before choosing that path for compliance reasons alone.
Connic's answer is explicit: a German contract counterparty, EU-hosted platform data, and EU-hosted connic/* inference. Deployment regions and customer-configured components determine the rest of the Project boundary.

Where Mastra genuinely fits
If your team writes TypeScript and your agents live inside a Next.js, Express, or Hono app, Mastra is a coherent choice. Version 1.0 shipped in January 2026, the Apache 2.0 core can run on your own infrastructure, and Mastra Platform now offers managed EU regions. Its code-based evaluations, Studio experiments, memory, approvals, webhooks, and cron cover a broad development surface.
Connic still differs on the German counterparty, first-party Kafka, SQS, email, and Postgres triggers, managed guardrail enforcement, and traffic splits between agent versions. Mastra's public docs do not show those same controls and connectors.

Connic vs Inngest + AgentKit
Durable-execution platform with a JavaScript and TypeScript agent framework, evals, experiments, and human-in-the-loop workflow patterns. Managed Cloud database data is US-hosted; self-hosting is the documented residency alternative.
Connic vs Agentuity
Agent infrastructure with usage pricing, managed queues, tasks, schedules, email, storage, databases, observability, eval workflows, and public or private deployment models. Public EU control-plane residency is not clearly documented.
Connic vs Trigger.dev
Open-source, Git-first background-job platform with AI tasks, HITL patterns, Realtime, and LLM usage metrics. EU run execution does not relocate payloads or logs; complete residency requires self-hosting or a confirmed private deployment.
Connic vs LangChain
MIT-licensed Python and JavaScript framework with more than 1,000 integrations. The framework remains self-hosted code, while the vendor's LangSmith platform adds managed deployment, tracing, and EU-region options under a US contract.
Connic vs AutoGen and Microsoft Agent Framework
AutoGen is in maintenance mode, with Microsoft Agent Framework as its successor. The successor can run as self-hosted SDK code or through Foundry Hosted Agents, where residency depends on the selected resources, models, and tools.
Connic vs CrewAI
MIT-licensed Python and YAML framework plus CrewAI AMP for managed deployment, tracing, evaluations, integrations, knowledge, and approvals. Standard managed-region choice is not publicly specified; Enterprise offers vendor cloud, customer VPC, or customer infrastructure.
