Tilde vs Mastra

The short answer

Mastra and Tilde are both TypeScript-first, but they solve different parts of the problem. Mastra gives you the building blocks to write an agent in code. Tilde gives that agent secure access to real systems, protects what goes in and out of it, and gives your organisation control over what it can do.

If you're choosing a framework to write agent logic, Mastra is a strong option. If you need hundreds of authenticated integrations, managed credentials, security middleware, workspace-level access and channels without building them yourself, that's where Tilde fits. Many teams will want both.

At a glance

Where Mastra is strong

Mastra packs a lot into one framework. Agents, workflows with suspend and resume, several kinds of memory, RAG, evals and tracing all live in the same TypeScript codebase. Its guardrail processors can detect prompt injection and personal data, and its local Studio makes it quick to test an agent before you ship it.

It's open source under Apache 2.0, runs on serverless platforms, and deploys to Vercel, Netlify, Cloudflare, AWS and Kubernetes. It acts as both an MCP client and an MCP server. If your team wants to own the whole agent in code, that's a real advantage.

Where Tilde is different

Most of the hard work in production agents isn't the agent loop. It's connecting to the systems your business already uses, safely, and staying in control as more teams build agents. Tilde focuses on that 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 Mastra and Tilde together

You don't have to pick one. Mastra agents are MCP clients, so they can call tools served by Tilde. Point a Mastra agent at a Tilde MCP server and it gets authenticated access to your integrations, while Tilde keeps the credentials, applies security middleware and checks permissions.

You can also register a deployed Mastra agent in the Tilde Registry, and connect it to users through Tilde channels. It gets an owner, an access scope and a place in your organisation's inventory, alongside agents built with other frameworks.

Which should you choose?

• Choose Mastra if you want an open-source framework to write agent logic, workflows and memory, and you're happy to build integrations, credential storage and channel adapters yourself.
• Choose Tilde if you need many authenticated integrations, managed credentials, security middleware, workspace-level access, approvals or channels, in Tilde cloud or on-prem.
• Use both if you like writing agents in Mastra and want Tilde to handle tools, credentials, security and access. Talk to our team if you'd like help planning it.
