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 $250 per month. Usage above the allowances is billed for CPU, egress and observability events.
The same agent in connic and Mastra
A claims agent with one tool that looks up a policy. In connic it is a YAML file and a Python function. In Mastra it is a TypeScript tool and agent, registered on a Mastra instance.
connic
name: claims-intake
model: connic/gpt-5.6-sol
system_prompt: Check the policy first.
tools:
- policies.lookup_policyimport os
import httpx
API = os.environ["POLICY_API_URL"]
async def lookup_policy(policy_id: str) -> dict:
"""Look up a policy by number.
Args:
policy_id: Policy number from the claim
"""
url = f"{API}/policies/{policy_id}"
async with httpx.AsyncClient() as client:
response = await client.get(url)
return response.json()Mastra
import { createTool } from "@mastra/core/tools";
import { z } from "zod";
const API = process.env.POLICY_API_URL;
export const lookupPolicy = createTool({
id: "lookup-policy",
description: "Look up a policy by number",
inputSchema: z.object({ id: z.string() }),
execute: async ({ id }) => {
const res = await fetch(`${API}/policies/${id}`);
return res.json();
},

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

| Feature | connic | Mastra |
|---|---|---|
| Language & ecosystem | ||
| Python toolsconnic agents are YAML files, and their custom tools are Python functions. Mastra is TypeScript-only and has no Python SDK. | Yes | No |
| TypeScript and JavaScriptMastra is TypeScript-first, with integrations for Next.js, Express and Hono. connic's SDK and custom tools use Python, and TypeScript apps call connic agents over HTTP or WebSocket. | Partial | Yes |
| 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. | Yes | No |
| Triggers & integrations | ||
| Webhook triggersBoth accept webhooks. Mastra's WebhookSignalProvider is called from an endpoint you mount yourself. | Yes | Yes |
| Cron schedulingBoth run agents on a schedule. | Yes | Yes |
| 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. | Yes | Partial |
| 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. | Yes | No |
| Stripe eventsBoth handle Stripe events. Mastra receives them through its webhook signal provider. | Yes | Yes |
| 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. | Yes | No |
| Chat channelsconnic has Slack and Telegram connectors, plus Twilio and Telnyx for messaging and voice. Mastra documents channels for Slack, Microsoft Teams, Discord, Telegram, WhatsApp, GitHub and iMessage. | Yes | Yes |
| Production controls | ||
| Tracing and run historyBoth trace every run. connic includes tracing on every paid plan; Mastra Platform meters observability events per plan. | Yes | Yes |

| EU & compliance | ||
| Managed EU data residencyconnic keeps platform data and connic/* inference in the EU. A Mastra Platform environment can pin its server, database and observability to the EU region chosen at creation. | Yes | Yes |
| EU contract partnerconnic contracts through a German company. Mastra contracts through Kepler Software Inc., a Delaware corporation. | Yes | No |
| EU AI Act mappingconnic maps execution logs, approvals and guardrails to deployer obligations. Mastra publishes GDPR guidance and documents logs and approvals, without a mapping to the Act. | Yes | No |
| Pricing | ||
| No per-seat pricingconnic developer and pro start at €40 and €200 per month. Mastra Starter is free and Teams costs $250 per month, both with unlimited users. | Yes | Yes |
| 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. | Yes | No |
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.
