I wanted to take something super simple and see if I would be able to make it world-class for the AI era. Timers are a dime a dozen (Apple even uses them as an example of an app not to try to submit to the Apple App Store because it’s already filled with them), but eggtimer.app is your timer for the AI era because it can interface with LLMs, agents, Zapier, etc. One of my favorite features is that you can make a shared timer by creating one and sharing the link. It will finish on all computers at the same time. Feedback appreciated!
About
eggtimer.app
Eggtimer.app is a free online timer with shareable countdown links, custom routines, an MCP server for AI assistants, and webhooks for automation. You can use it for anything from a five-minute break, to a Pomodoro session, to a cooking sequence, or even use it as a server timer that signals another app when to act.
Start a timer by typing a time
Enter 5m, 1h20m, or 9pm and press Enter. You can go straight to eggtimer.app/5m or in your browser tab, just type 15.eggtimer.app or 1h.eggtimer.app to make starting a countdown as quick as typing an address. Use your address bar as a timer-launcher.
Make a shareable routine
Use the built-in Pomodoro and Tabata timers, a stopwatch, or create your own sequence of labeled/ named stages. Add work/rest cycles, intervals, colors, a ring or progress-bar display, and a finished! message. Recipes can be edited visually, exported as JSON, shared with a link, and remixed by a friend or an AI assistant.
Give AI assistants a timer tool
Most innovatively, eggtimer.app supports the Model Context Protocol (MCP), so AI clients can discover timer presets, validate a duration, and return a usable countdown or timer recipe link. The public MCP endpoint is eggtimer.app/api/mcp and it needs no account or API key. The same features are available through HTTP API, OpenAPI reference, and recipe schema.
Run a timer after the browser closes
For automation, you can create a private workspace and schedule a real server timer by duration or with a specific date and time. The saved deadline continues independently of your browser. You can read its status, cancel a pending timer, or send a completion event to Zapier via Catch Hook. MCP clients are able to schedule and manage eggtimer.app server timers via eggtimer.app/api/mcp/server using a workspace API key. This makes a timer useful inside an agent task or in a workflow.
Keep timer links useful
Share a reusable timer or recipe setup so someone else can start their own session. Copy an individual timer’s URL to reopen the same timer somewhere else. Recipe step links can point to a specific stage. Authenticated server timer links work across devices so that new countdown timers are kept separate from any links to an existing run.
A small app for everyday use
Eggtimer.app can be installed as a progressive web app (PWA), with an offline shell for browser timers and recipes. (One limitation is that browser sound needs an active page and a device that allows playback; server timers send events and cannot ring a native phone alarm)
Access and privacy
Browser timers and public link-building tools are free; no signup needed. Server automation is a free, limited beta: 50 new timers per workspace, per day, ten at the same time, and deadlines up to 30 days ahead (subject to shared service limits). No email or payment is needed to create a workspace.
For people, makers, and workflows
Use eggtimer.app for focus sessions, study, cooking, classroom activities, presentation stages, workout intervals (including the famous "beep test"!), or any task that should continue once a previous. countdown finishes. Start with a simple link, build a reusable routine, or connect the API and MCP tools to customize your own workflow. Zapier integration is currently invite-only; direct Catch Hook delivery is available through the server timer API.
