A managed runtime that doesn't pick your framework for you
LangSmith Deployment is the home for LangGraph agents. Connic runs any Python agent with connectors, tracing, evals, and EU residency under a German contract, on the same plan.
If your team has already committed to LangGraph, LangSmith Deployment is the obvious runtime, and its trace tooling is deservedly the most adopted in the LangChain ecosystem. The comparison gets interesting when you have not made that commitment yet, or when procurement asks two questions the framework cannot answer: who is the contract counterparty, and where does every piece of the production stack live?
Connic answers both by construction: a German company, 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. LangSmith answers the first with a US contract on every tier, and the second with a guarantee that covers its own primitives but not the tooling you wire in around them.
Feature Comparison
Connic vs LangSmith Deployment, capability by capability.
Framework & Design
Framework-independent runtime
Connic runs any Python agent code. LangSmith Deployment is the managed runtime for LangGraph agents specifically.
YAML-based agent config
Connic defines agents declaratively in YAML with Python tools. LangGraph uses code-only graph construction.
Simpler mental model
Connic: YAML + Python functions. LangGraph: nodes, edges, checkpointers, state schemas.
MCP support
Both expose and consume MCP-compatible tools.
EU & Compliance
Managed EU data residency
Both offer it. Connic hosts EU-only by default; LangSmith runs an EU instance (Netherlands) available on all plans, including deployments.
EU contract counterparty
Connic contracts through a German company. LangSmith agreements run through LangChain, Inc. (US) on every tier.
EU AI Act tooling
Connic ships execution logs, human approvals, and guardrails mapped to deployer obligations. On LangSmith, Act evidence is something you build into agent code.
Full production stack in one EU region
Connic's traces, judges, guardrails, and approvals live in the same EU region as the runtime. LangSmith's guarantee covers traces and deployments; tooling wired in from libraries runs wherever you run it.
Deployment & Operations
Git-based deployments
Both support deploying from source. Connic uses push-to-deploy from your Git provider.
Managed hosting
Both offer managed cloud hosting. Connic includes it in every paid plan; LangSmith Deployment provides one free dev-sized deployment on the Plus tier.
Self-hosted / hybrid option
LangSmith Deployment offers hybrid and self-hosted on Enterprise. Connic offers self-hosted on Enterprise as well.
Environment management (dev / staging / prod)
Connic has built-in environments on every paid plan. LangGraph manages deployments at the account level.
Integrations & Triggers
Webhook triggers
Native in Connic. LangSmith Deployment exposes agents via its API; you wire webhooks yourself.
Cron scheduling
Both offer built-in cron scheduling.
Message queues (Kafka, SQS)
Native Kafka and SQS connectors in Connic. LangGraph requires you to build and maintain consumer workers.
Email triggers
Native email connector in Connic. LangGraph requires external forwarding and a custom handler.
Stripe event triggers
Native Stripe connector in Connic. LangGraph requires a webhook handler you build and host yourself.
Postgres connector
Native Postgres connector for triggers and actions in Connic. LangGraph requires custom integration code.
Observability & Evals
Tracing and run history
Both include tracing. LangSmith's is industry-leading for LangChain-family projects.
Included in base plan
Connic includes tracing on every tier. LangSmith Deployment plans bundle trace allowances (5k/10k base traces) with pay-as-you-go above.
Built-in judges / evals
Both ship eval capabilities. LangSmith has mature eval tooling; Connic's judge service is first-party.
A/B testing with traffic splits
Connic runs statistical A/B tests between agent versions in production. LangSmith compares eval runs offline.
Pricing
Not billed per seat
Connic subscriptions are monthly usage credit (Developer €40, Pro €200) at identical per-unit rates; adding teammates doesn't change the bill. LangSmith bills per seat plus usage.
Subscription doubles as usage credit
A Connic plan is credit you consume at published rates (€0.047/run, €0.00042/sec compute). LangSmith plans bundle allowances with pay-as-you-go above them.
The EU question
Credit where due: LangSmith's EU instance is real. It is available on every plan including the free tier, and deployments are served from it, not just traces. Among US platforms, that is the strongest managed EU residency story in this category.
What it cannot fix is the contract and the scope. Agreements run through LangChain, Inc., a US corporation with no EU entity, on every tier, and the EU instance runs on US-owned cloud infrastructure, which answers the residency question but not the sovereignty question your DPO may ask next. And the guarantee covers the platform's own primitives. The evaluation harnesses, guardrails, and approval flows you wire in from LangChain libraries run wherever you run them, each with its own residency answer to collect.
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 LangSmith Deployment genuinely fits
If your agents are LangGraph graphs today and your team lives in the LangSmith trace UI, the first-party runtime is a coherent choice: one vendor for framework, traces, and deployment, with a builder (Fleet) layered on top. The ecosystem is the moat, and it is a real one.
The calculus changes when the requirement list grows past the framework: event-driven triggers from Kafka, Stripe, or email that you would otherwise build as custom consumers; an EU counterparty for procurement; approvals and A/B testing as platform features instead of library code. That is the point where a framework-independent runtime 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
LangSmith Deployment is the right home for LangGraph agents. Connic is the right home for any Python agent you want in production fast, with connectors, observability, and EU compliance bundled.
Use Connic when
- You don't want to be locked to a specific agent framework
- EU data residency and an EU contract counterparty are procurement requirements
- You need enterprise connectors (Kafka, SQS, Stripe, Postgres, Email) day one
- You want approvals and A/B testing as platform features, not library code
- You want monthly usage credit rather than per-seat + usage
Use LangSmith Deployment when
- You're already committed to LangGraph and want the first-party managed runtime
- You need LangSmith's mature tracing and eval ecosystem for LangChain-family projects
- Your team builds in LangSmith Fleet as part of its dev loop
- Per-seat billing fits your procurement better than credit-based plans
- You need hybrid or self-hosted deployment on day one (Enterprise tier)

Connic vs Vercel
Agentic infrastructure with the eve framework and AI Gateway. Compute can run in Frankfurt — Gateway logs, workflow state, and queue state cannot. Connic keeps every plane in the EU.
Connic vs n8n
German workflow-automation platform with LangChain-based agent nodes. Strong at visual process automation — a different shape from an agent-native runtime with cost tracking and A/B testing.
Connic vs Mastra
TypeScript-only agent framework with Mastra Server and Cloud. Deep TS integration — and a language lock-in if your stack ever changes.
Connic vs Inngest + AgentKit
Durable-execution platform with an open-source agent framework layered on. Strong fit for JS/TS teams — different shape from a runtime built for agents from day one.
Connic vs Agentuity
Purpose-built agent infrastructure on pure usage-based pricing. Flexible — but hard to forecast when finance needs a number.
Connic vs Trigger.dev
Open-source, git-first background-job platform now shipping AI Agents and Realtime. Strong if jobs are the core — thinner if your agents need memory, evals, and connectors out of the box.
