A harness SDK for building cloud deployed AI agents, fast
Tilde is a harness SDK for building cloud-deployed AI agents extremely fast. It addresses the problem that a single agent harness for both simple and highly complex tasks leads to sub-optimal outcomes, and existing harness libraries lack the developer experience, portability, and composability the creator wanted. Tilde provides composable components—Tools, ChatKit, and Memory—so developers can pick and choose what to give their agents.
Tilde is designed for software engineers who want to build and deploy AI agents securely in the cloud without managing the underlying infrastructure. Everything is cloud-based, centrally managed, and permissioned, and credentials are never exposed to agents or sandboxes. The SDK currently works with Vercel's AI SDK, with plans for other frameworks and languages. The platform is highly portable: a tilde-state.yaml file can be imported to set up required Tilde infrastructure and integrations quickly, as demonstrated in the code review agent example.
Tilde lets you pick and choose components like Tools, ChatKit, and Memory to compose into your agent harness, avoiding a one-size-fits-all approach.
Spin up MCP servers, add Tilde-managed tools, bring your own, or proxy upstream MCP servers. Includes credential management, SaaS integrations, and raw HTTP/1.1 and HTTP/2 reverse proxies.
Integrate agents with Slack, GitHub, or via API and webhooks, letting agents send and receive messages where your team already works.
Create and centrally manage skills registries, wikis, and persistent memories, surfaced as tools so agents can autonomously keep up to date.
All Tilde infrastructure is cloud-based, centrally managed, and permissioned, keeping credentials secure and away from agents and sandboxes.
A client-side library works with Vercel's AI SDK today, with support for other frameworks and languages expected in the future.
A tilde-state.yaml file can be imported into a Tilde account to set up required infrastructure and integrations, making your setup portable and reproducible.
Tilde is a harness SDK for building cloud-deployed AI agents extremely fast. It provides composable components like Tools, ChatKit, and Memory, and handles infrastructure, credential management, and permissions.
Tilde is cloud-based and centrally managed. Credentials are managed by Tilde and never exposed to the agent or the sandbox where the agent runs. The code review agent example uses this to securely check out code without credential leakage.
Tilde's ChatKit supports third-party chat providers like Slack and GitHub, plus direct API and webhooks. The Tools component supports MCP servers, Tilde-managed tools, bring-your-own tools, and raw HTTP reverse proxies to upstream services.
Yes. The page describes an example agent that can be instantly deployed to Vercel & Tilde for remote usage. The client-side library works with Vercel's AI SDK.
It's a state file in the example GitHub repo. You can spin up a Tilde account, head to settings, and import it to set up the required Tilde infrastructure and integrations. You then configure GitHub and Modal sandbox settings, making the system portable.
The creator states it's ready after working through common pitfalls, and shares a deployable code review agent example. However, the docs are noted as needing a refresh, so expect them to improve.
