The short answer

Mastra suits a TypeScript team that builds agents into its own app and wants Apache 2.0 code it can self-host. connic suits teams that run agents as their own service, started by queues, inboxes and databases, and released after a test on live traffic.

Use connic when

  • Your agents run as their own service, with tools in Python
  • Kafka, SQS, email or Postgres events should start agents
  • New versions should prove themselves on live traffic first
  • Guardrails should run on the platform for every request
  • You need EU hosting and an EU contract partner

Use Mastra when

  • Your team writes TypeScript and wants agents inside its app
  • You want Apache 2.0 code you can self-host
  • Chat channels like Discord, WhatsApp or iMessage are the main entry point
  • You want managed OAuth tools for apps like GitHub and Notion (Mastra Connect, in beta)
  • A US contract partner with an EU region meets your requirements

Where connic and Mastra differ

What each platform does in the areas that usually decide an evaluation.

How agents are built

connic

An agent is a YAML file with its model, prompt and tools. Custom tools are Python functions, and apps in any language call the agent over HTTP or WebSocket.

Mastra

Agents and tools are TypeScript code in a Mastra app, often next to Next.js, Express or Hono. There is no Python SDK.

What starts a run

connic

Connectors for Kafka, SQS, email, Postgres, Stripe, webhooks, cron, Slack and more. Each one is a file in your project, deployed with the agents.

Mastra

Webhooks through a signal provider you mount, schedules, and chat channels such as Slack, Discord and WhatsApp. Kafka, SQS, inbound email and Postgres triggers are not documented.

Releasing a new version

connic

Built-in A/B tests send a share of live traffic to a variant and compare success rate, judge scores, cost and latency.

Mastra

The Editor serves a chosen agent version per request. The traffic split and the statistics are yours to build.

Guardrails

connic

Input and output checks run on the platform for every run, with nine built-in checks or your own in Python.

Mastra

Processors for prompt injection, PII and moderation, configured in agent code.

Evals and approvals

connic

Judges score sampled production runs against a rubric. Approvals pause a tool call until a reviewer decides.

Mastra

Code and LLM scorers, datasets and experiments. Tool calls can require approval and resume afterwards.

Hosting

connic

Managed runtime with environments on every paid plan. Self-hosting on enterprise.

Mastra

The Apache 2.0 core runs anywhere, with a Helm chart for Kubernetes. Mastra Platform hosts deployments in US or EU regions.

EU and contract

connic

Platform data and connic/* inference stay in the EU. The contract partner is a German company.

Mastra

An EU region can be picked per environment at creation, and US is the default. The contract partner is Kepler Software Inc. in the US.

Pricing

connic

Developer and pro start at €40 and €200 per month, and the plan amount becomes Project credit at published base rates.

Mastra

Starter is free and Teams costs $250 per month. Usage above the allowances is billed for CPU, egress and observability events.

The same agent in connic and Mastra

A claims agent with one tool that looks up a policy. In connic it is a YAML file and a Python function. In Mastra it is a TypeScript tool and agent, registered on a Mastra instance.

connic

agents/claims-intake.yaml
name: claims-intake
model: connic/gpt-5.6-sol
system_prompt: Check the policy first.
tools:
  - policies.lookup_policy
tools/policies.py
import os
import httpx

API = os.environ["POLICY_API_URL"]

async def lookup_policy(policy_id: str) -> dict:
    """Look up a policy by number.

    Args:
        policy_id: Policy number from the claim
    """
    url = f"{API}/policies/{policy_id}"
    async with httpx.AsyncClient() as client:
        response = await client.get(url)
        return response.json()

Mastra

src/mastra/tools/lookup-policy.ts
import { createTool } from "@mastra/core/tools";
import { z } from "zod";

const API = process.env.POLICY_API_URL;

export const lookupPolicy = createTool({
  id: "lookup-policy",
  description: "Look up a policy by number",
  inputSchema: z.object({ id: z.string() }),
  execute: async ({ id }) => {
    const res = await fetch(`${API}/policies/${id}`);
    return res.json();
  },
});
src/mastra/agents/claims-intake.ts
import { Agent } from "@mastra/core/agent";
import { lookupPolicy } from "../tools/lookup-policy";

export const claimsIntake = new Agent({
  id: "claims-intake",
  name: "Claims intake",
  instructions: "Check the policy first.",
  model: "openai/gpt-5.6-sol",
  tools: { lookupPolicy },
});
src/mastra/index.ts
import { Mastra } from "@mastra/core";
import { claimsIntake } from "./agents/claims-intake";

export const mastra = new Mastra({
  agents: { claimsIntake },
});

Agents independent of the client's languageApps in any language reach connic agents through connectors. Mastra agents are code in a Mastra app that deploys to Mastra Platform or another host, so leaving the framework means rewriting them.YesNo
Triggers & integrations
Webhook triggersBoth accept webhooks. Mastra's WebhookSignalProvider is called from an endpoint you mount yourself.YesYes
Cron schedulingBoth run agents on a schedule.YesYes
Kafka and SQSconnic's Kafka and SQS connectors consume and publish messages. Mastra's pub/sub layer on Redis Streams or Google Cloud Pub/Sub carries its own workflow events, and its docs do not describe Kafka or SQS consumers.YesPartial
Email triggersconnic's email connector starts runs from an inbox and can send results by email. Mastra documents Gmail and Resend tools for agents but no inbound email trigger.YesNo
Stripe eventsBoth handle Stripe events. Mastra receives them through its webhook signal provider.YesYes
Postgres event triggersconnic's Postgres connector starts runs from NOTIFY events, so a table trigger can start an agent. Mastra uses Postgres for storage, and Mastra Connect gives agents Supabase query tools, but no Postgres trigger is documented.YesNo

Plan fee becomes usage creditconnic turns the plan amount into Project credit, used at published base rates before package discounts: €0.0337 per started LLM-agent run, €0.00042 per runtime second and €0.00342 per GB-hour of storage. Mastra plans include allowances and bill overages on top, such as $0.35 per CPU hour on Starter and $0.25 on Teams.YesNo

Methodology

We compare generally available capabilities documented in each vendor's product, pricing, security, and legal material. Yes means documented support, Partial means limited scope, beta or preview status, or additional setup, and No means unavailable or not documented in the sources reviewed. connic capabilities are checked against current product documentation, and roadmap claims are not scored.

Mastra ships platform features at a fast pace, including Mastra Connect in October 2026, so negative capability claims were checked against its docs and release notes as well as its current plan table.

connic vs Inngest + AgentKitDurable-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 AgentuityAgentuity, a managed platform for AI agents, was discontinued in 2026. This page maps its agents, triggers, storage, evals and hosting to connic for teams moving their agents.connic vs Trigger.devOpen-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 LangChainMIT-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 + Microsoft Agent FrameworkAutoGen 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 CrewAIMIT-licensed Python framework with JSONC or YAML agent files, 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.

Frequently Asked Questions

Yes, for teams that want a managed platform instead of a framework. connic runs YAML agents with Python tools and includes event connectors, judges, guardrails, approvals and live A/B tests. Platform data and connic/* inference stay in the EU under a German contract.

No. Mastra is TypeScript-only and has no Python SDK. connic agents use Python for custom tools, and TypeScript apps can still call them over HTTP or WebSocket.

Yes. Since July 2026, a Mastra Platform environment can pin its server, hosted database and observability to the EU region. The region is fixed once the environment exists, and US is the default. Model providers need their own review, and the contract runs through Kepler Software Inc. in the US. The EU data residency shortlist compares the other platforms on the same points.

The core framework is Apache 2.0, relicensed from the Elastic License in July 2025. Code in the ee/ directories falls under the source-available Mastra Enterprise Edition License, which requires a license key and a signed agreement for production use. Mastra Platform is the commercial managed offering.

Mastra Starter is free and Teams costs $250 per month, both with unlimited users and deployments. Usage above each plan's allowance is billed on top, such as CPU hours, egress and observability events. connic developer and pro start at €40 and €200 per month, and the plan amount becomes Project credit for runs, runtime and storage. Enterprise terms are custom on both.

Mastra's Editor lets your code request a specific agent version, and its docs list A/B tests as a use. The traffic split and the statistics live in your application. connic splits live traffic itself and compares success rate, judge scores, cost and latency. In Confidence mode, it decides at planned looks.
