Meerkat — Open source async agent task API
kannanreghu · 2026-06-27 · via Hacker News: Show HN

Open source · MIT · BYOK · Webhook-native

Describe a task in your own words. Meerkat runs it async.

Open source API for developers who need agents to monitor links, track deliveries, and report findings — without building schedulers, webhook plumbing, or LLM tool loops. Results POST to your endpoint.

Self-host anywhere · Run on the stack you already ship

01 · The primitive

One verb. Register.

Every product that watches the world rebuilds the same stack: schedulers, LLM tool loops, page diffing, webhook retries. Meerkat collapses that into a single open source resource.

register

POST /api/v1/tasks

Describe in English. Pass input_params + output_webhook.

run

scheduled · on-demand

Cron, natural language, or POST /tasks/:id/run.

return

your webhook

Structured JSON, signed, retried until 2xx.

02 · Lifecycle

From cURL to webhook. Four hops.

06 · Architecture

Your app Meerkat LLMs.

A task moves through three actors. You register it, Meerkat schedules and orchestrates, an LLM (your key) executes, and a signed webhook lands back at your endpoint.

03 · Self-host

Deploy your own in one click.

Self-host Meerkat with the same REST API as Cloud. You run Postgres and workers; users connect their own LLM keys. MIT licensed, no vendor lock-in.

$ git clone github.com/Tiny-Bubble-Company/meerkat

04 · Run it your way

Self-host or Cloud.

Same open source codebase. Same API. Pick the operating model that fits your team.

open source Free · MIT

Self-host

  • Docker, Render, Fly.io, or Kamal
  • Full REST API + webhook delivery
  • Users bring LLM keys (BYOK)
  • You operate Postgres + job workers

recommended

managed Monthly subscription

Meerkat Cloud

  • Same API — no workers to run
  • Managed queues + webhook delivery
  • BYOK — Anthropic, OpenAI, OpenRouter, Grok
  • LLM usage billed by your provider

Sign up free →

05 · BYOK

Bring your own LLM key.

Meerkat never resells AI tokens. Each account connects an encrypted API key. Model costs go to your provider; Meerkat charges only for scheduling, execution, and webhooks.

Configure in docs →

couriers recurring · webhook

Tracking that pings you, not the other way around.

Drop in DHL, FedEx, or UPS URLs. Meerkat polls, diffs, and webhooks only when the state actually moves.

status: "Out for delivery" · eta: "16:40"

Learn more →

price · stock recurring · webhook

Watch any product. Pay only when something changes.

Price drops, restocks, availability shifts — converted into compact JSON your app can react to in one route.

price: 89.00 → 72.50 · in_stock: true

Learn more →

page diffs recurring · webhook

Competitor pages, docs, status sites — observed.

Per-run snapshots are diffed against history. You get a summary of what changed, not an HTML payload to parse.

changed: ["pricing.enterprise", "h1.copy"]

Learn more →

one_off recurring · webhook

Ad-hoc fetches without standing up a scheduler.

Fire a single task for research, scraping, or extraction. Marked complete after the webhook lands.

task_type: "one_off" · status: "succeeded"

Learn more →

08 · API surface

REST. Boring on purpose.

JSON in, JSON out. Bearer auth. Idempotent retries. Signed webhooks. The whole surface fits on one screen — identical between self-host and Cloud.

$ meerkat init

Stop building the same async stack.

Sign up free, connect your LLM key, and ship your first webhook in under five minutes. Or deploy the open source version yourself — same API, your infrastructure.
