Meerkat is an open-source API designed for developers seeking to automate asynchronous agent tasks such as monitoring links, tracking deliveries, and detecting changes on websites. It enables users to describe tasks in plain English, which are then executed asynchronously by connected large language models (LLMs). Task results are delivered to user-defined webhook endpoints in structured JSON, with webhook payloads signed using HMAC-SHA256 and retried with exponential backoff until acknowledged.
Developers can register both one-off and recurring tasks via a REST API, specifying scheduling options through either cron syntax or natural language. Meerkat handles the full lifecycle of each task: after registration, it schedules and orchestrates execution, invokes LLMs for processing, and posts results to the specified webhook. The architecture involves three actors: the client application, Meerkat's infrastructure for scheduling and orchestration, and the LLM for execution. Supported use cases include tracking package statuses from courier services, monitoring product prices and stock, observing competitor web pages for changes, and performing ad-hoc data extraction or research tasks.
Meerkat supports integration with several LLM providers, including Anthropic, OpenAI, OpenRouter, and Grok, using a bring-your-own-key (BYOK) model. Users connect their own encrypted API keys, and Meerkat does not resell AI tokens; model usage is billed directly by the provider. The platform charges only for scheduling, execution, and webhook delivery, and all model API keys are encrypted at rest.
The API is MIT licensed, emphasizing open-source accessibility and no vendor lock-in. Meerkat can be self-hosted using Docker, Render, Fly.io, or Kamal, requiring users to operate their own Postgres database and job workers. Alternatively, a managed cloud version is available via monthly subscription, offering the same API and open-source codebase without the need to run infrastructure. This flexibility allows teams to deploy Meerkat in a way that fits their operational needs.
Meerkat sits in PulseGate's Autonomous agents & workflows category. It focuses on automating asynchronous agent tasks and reporting results to webhooks without building custom schedulers or agent loops. Meerkat is an open-source project aimed at developers building agent-based automation or monitoring systems. The project is open source (MIT). It runs on API, and it can be self-hosted.
Meerkat first shipped in 2026. The project is developed in the open on GitHub with 23 commits in the last 90 days. Among its 5 catalogued features are webhook integration, task scheduling, and async agent tasks. It exposes integrations via a public API.
