Pick by fit, not by which language your team writes
Mastra is TypeScript-only by design. Connic is language-agnostic and EU-hosted under a German contract: Python today, more runtimes ahead, with first-party Kafka, SQS, Stripe, Postgres, and email connectors in place of glue you'd write inside your framework.
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. If your agents are TS modules inside a larger web app, it deserves the attention it gets. The comparison sharpens when procurement joins the call, because the framework cannot answer the two questions they ask first: where does the managed cloud host your data, and who signs the contract?
Connic answers both by construction: a German company as counterparty, EU-hosted regions by default, and the production surface an agent needs (traces with cost tracking, judges, guardrails, approvals, A/B testing, connectors) shipped as one platform in one region. Mastra Cloud is in public beta and does not document EU data residency, so the EU path is self-hosting the open-source core, with everything that operating it implies.
Feature Comparison
Connic vs Mastra, capability by capability.
Language & Ecosystem
Supports Python
Connic's primary agent runtime is Python. Mastra is TypeScript-exclusive by design (their tagline: "Python trains, TypeScript ships").
Supports TypeScript / JavaScript
Mastra is TS-first with deep Next.js / Express / Hono integration. Connic's first-party SDK is Python.
Framework-independent
Connic runs any agent code. Mastra is both the framework and the deployment target, so leaving Mastra means a rewrite.
EU & Compliance
Managed EU data residency
Connic hosts EU-only by default. Mastra Cloud is in public beta and does not document EU data residency; the documented EU path is self-hosting the Apache 2.0 core.
EU contract counterparty
Connic contracts through a German company. Mastra has no EU legal entity.
EU AI Act tooling
Connic ships execution logs, human approvals, and guardrails mapped to deployer obligations. Mastra has no equivalent platform surface; Act evidence is something you build in framework code.
Full production stack in one EU region
Connic's traces, judges, guardrails, and approvals live in the same EU region as the runtime. On self-hosted Mastra, each piece of that stack is a tool you pick, run, and answer for separately.
Deployment & Operations
Managed hosting included
Connic includes managed hosting on every paid plan. Mastra Cloud is in public beta; production-grade limits require the Teams tier ($250/team/mo).
Git-based deployments
Both support deploying from source.
Environment management (dev / staging / prod)
Connic has built-in environments on every paid plan. Mastra's environment model is per team.
Self-hosted option
Mastra is Apache 2.0 and fully self-hostable. Connic offers self-hosting on Enterprise.
Integrations & Triggers
Webhook triggers
Native in Connic. Mastra exposes agents through framework integrations (Next.js / Express / Hono); you wire triggers yourself.
Cron scheduling
Native cron connector in Connic. Mastra has no first-party scheduler; you add one.
Message queues (Kafka, SQS)
First-party Kafka and SQS connectors in Connic. Mastra requires custom integration code.
Email triggers
Native email connector in Connic. Mastra requires external handling.
Stripe event triggers
Native Stripe connector in Connic. Mastra requires a webhook handler you host yourself.
Postgres connector
Native Postgres triggers and actions in Connic. Mastra integrates via framework database libraries.
Observability & Evals
Tracing and run history
Mastra has built-in tracing and Studio observability. Connic includes tracing in every paid plan.
Built-in judges / evals
Mastra has framework-level eval tooling (model-graded, rule-based, statistical) you run in code. Connic's judge service is a managed platform primitive.
Agent memory
Mastra has a dedicated Memory Gateway (separate paid surface). Connic includes agent memory in the platform.
Guardrails as a platform primitive
Connic gates agent turns at the platform level. Mastra ships guardrails as framework code, not a managed platform primitive.
Human approvals (HITL)
Connic has a first-party approval queue. HITL approvals are not a Mastra platform primitive.
A/B testing with traffic splits
Connic runs statistical A/B tests between agent versions in production. A/B testing is not a Mastra platform primitive.
Pricing
Not billed per team or per seat
Connic subscriptions are monthly usage credit (Developer €40, Pro €200, Enterprise custom) at identical per-unit rates. Mastra Teams is $250 per team per month, which stacks as your org grows.
Subscription doubles as usage credit
A Connic plan is credit you consume at published rates (€0.047/run, €0.00042/sec compute, €0.25/GB-month storage). Mastra Cloud meters add-ons ($0.00008/s CPU, $10/GB egress) on top of the tier.
Memory billed as part of the platform
Connic includes agent memory in the platform. Mastra bills Memory Gateway separately (Starter free, Teams $250/team/mo).
The EU question
Credit where due: the self-hosting path is real. Mastra's core is Apache 2.0, so you can run it in any EU region you control, and for teams whose policy requires operating the runtime themselves, that is the strongest possible residency answer.
The managed product does not offer one. Mastra Cloud is in public beta and does not document EU data residency, and Mastra has no EU legal entity, so agreements run through a US company. That leaves self-hosting as the EU path, and self-hosting moves the residency problem rather than shrinking it: you operate the trace store, the upgrade path, and the on-call rotation, and the agent production surface (judges, guardrails, approvals, cost tracking) still has to come from somewhere, each tool with its own residency answer. Read what self-hosting actually costs before choosing that path for compliance reasons alone.
Connic's answer is structural: a German contract counterparty, EU-hosted regions by default, and the whole production surface, traces, judges, guardrails, approvals, inside that same region under one DPA. For how the whole field compares on this axis, read the EU data residency shortlist, or see how Connic maps its features to the EU AI Act.
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: a stable 1.0 as of January 2026, a well-funded company behind it, and an Apache 2.0 core you can take anywhere, including your own EU infrastructure. The framework-level eval and memory tooling pulls its weight for teams that want everything in code, and the developer experience is among the best in the TypeScript agent ecosystem.
The calculus changes when the requirement list grows past the framework: a managed runtime with documented EU residency, judges and approvals as platform features instead of framework code, event-driven triggers from Kafka, Stripe, or email that you would otherwise wire yourself, and an EU counterparty for procurement. That is the point where a managed EU platform stops being the alternative and starts being the default.
Why teams choose Connic
What you get on day one — without writing connectors, wiring observability, or running infrastructure.
The Bottom Line
Mastra is a strong choice for teams committed to TypeScript. Connic fits when you want a managed platform with EU residency, without locking into a single language or framework.
Use Connic when
- Your agent code is Python, or you want the option to change languages later
- EU data residency and an EU contract counterparty are procurement requirements
- You need enterprise connectors (Kafka, SQS, Stripe, Postgres, Email) without writing glue
- You want judges, approvals, and A/B testing as platform features, not framework code
- You prefer monthly usage credit over per-team pricing plus metered add-ons
Use Mastra when
- Your team is committed to TypeScript and wants deep framework integration (Next.js / Hono / Express)
- You value Apache 2.0 open source and full self-hostability out of the box
- You can self-host in your own EU infrastructure and carry the ops burden
- Your architecture already treats agents as TS modules inside a larger app
- You prefer a code-first framework over a YAML-driven platform
