The short answer
LangSmith started as an observability and evaluation tool for LLM apps and has grown into a platform for deploying agents too. It's a natural fit if your team builds with LangChain or LangGraph and wants tracing, evals and hosting from one vendor.
Tilde starts from a different place: what your agents are connected to, and what they're allowed to do. It serves tools from a catalog of hundreds of SaaS providers, manages the credentials behind them, screens agent inputs and outputs, and controls which people and agents can use them. You can bring agents built with any framework, including LangGraph.

Where LangSmith is strong
LangSmith's observability and evaluation tools are mature. You get detailed traces, dashboards and alerts, and a full evaluation workflow with datasets, experiments, LLM-as-a-judge and human review. It works with any framework, not only LangChain.
LangSmith Deployment hosts agents built with LangGraph, LangChain and several other frameworks, and can expose them as MCP tools. Fleet, the no-code agent builder, lets people create agents with their own OAuth credentials, connect them to Slack, Gmail or Teams, and review actions in an inbox.
Where Tilde is different
The biggest difference is depth at the integration and control layer.
- Integrations without the plumbing. Create MCP tool servers from our catalog of SaaS providers, proxy an existing MCP server, or forward requests to your own API.
- Credentials you don't have to build. Tilde handles OAuth, API keys and custom authentication, including encryption and rotation.
- Security middleware on every agent. Tilde blocks jailbreak attempts and redacts personal information (PII) in agent inputs and outputs.
- Access scoped to the work. Workspaces and grants limit which people and agents can reach which resources, with single sign-on through your OIDC provider.
- Control on sensitive actions. Govern checks policy, asks a person to approve and records the decision before an action runs.
- Channels in a single click. Add WhatsApp, Slack, Discord, Telegram or GitHub to an agent without writing an adapter. ChatKit adds message history, sessions, webhooks, schedules and agent-to-agent delegation.
- Secrets kept out of the model. The secure browser signs in to websites with injected credentials the agent never sees.
- Voice when you need it. Build realtime voice agents on the same tools and permissions.
- One inventory. The Registry records every agent, who owns it and who can use it, whichever framework built it.
- Runs where your data lives. Use Tilde cloud, or deploy Tilde on-prem in your own infrastructure. Embedded engineers can help you set it up.
Using LangSmith and Tilde together
If you already trace and evaluate with LangSmith, keep doing it. Build your LangGraph agents as usual, give them tools through Tilde MCP servers with security middleware in front, and register them in the Tilde Registry so your organisation knows who owns each one and who can use it.

- Choose LangSmith if tracing, evals and hosting LangGraph agents are your priority, and a single vendor for that workflow suits you.
- Choose Tilde if your agents need many authenticated integrations, managed credentials, security middleware, workspace-level access, approvals or channels, in Tilde cloud or on-prem.
- Use both if you want LangSmith's evaluation workflow alongside Tilde's tools and control layer. Talk to our team if you'd like to plan it together.
