AI usage limit trackers for AI startup founders
AI startup founders can match each limit tracker to one question: team spend, outages, or Codex reset timing. Options and checks follow.
SupaKeeper is published by LunarWerx, which makes some of the tools compared here.
The question to answer decides the tool: what the team has spent, whether a service is down, or when Codex limits reset. Codex Forecast gives a guess of the reset timing, not a promise. [1]
| Option | What the tool does | Price as stated |
|---|---|---|
| OpenAI Status | States that it is not aware of any issues affecting its systems. [2] Lists Codex uptime at 99.95% across 4 components. [2] | not published |
| ccusage | Analyzes token usage and costs from coding agent command-line tools, using local data. [3] | not published |
| IsDown | Outage data from 6,320+ vendors via API. [4] | Starter plan $27 per month, or $22 per month when paid annually. [4] |
| StatusGator | Monitors the status of 11,270+ services. [5] | not published |
| Codex Forecast | Gives a guess of the next Codex limit reset, not a promise. [1] | Free, with no account needed. [1] |
What AI startup founders need from AI usage limit trackers
An AI startup founder who uses Codex usually has three questions. How much usage has been spent, whether the services the startup relies on are up, and when limits come back. These are different questions, and they need different tools. Usage tools read what has been spent. Status tools report whether a service is having trouble. A reset tracker tries to say when limits refill.
A small team that shares one account may care most about spend by day, week or month, while a founder who depends on one service may want outage information first. Check whether a tool answers the question you have, because none of the three stands in for the others. The sections below say what each source states and nothing more.
OpenAI Status for AI startup founders
OpenAI Status states that it is not aware of any issues affecting its systems. [2]
It lists Codex at 99.95% uptime across 4 components. [2] ChatGPT shows 99.57% uptime across 16 components. [2]
If your startup relies on Codex, check that line before you assume a fault is on your side.
ccusage for AI startup founders
ccusage analyzes token usage, meaning the units an AI service counts your use in, along with costs, from coding agent command-line tools, using local data. [3]
It is licensed under MIT, an open source license. [3]
It can be run without a global installation, using npx, a command that runs a tool without installing it system-wide. [3]
IsDown for AI startup founders
IsDown's Starter plan for individuals costs $27 per month, or $22 per month when paid annually. [4]
Its Pro plan costs $49 per month, or $40 per month when paid annually ($480/year). [4]
IsDown's outage data covers 6,320+ vendors and is available via API. [4] If your startup depends on several vendors, check whether OpenAI and Codex are among the services it covers.
StatusGator for AI startup founders
StatusGator has built-in website monitoring that alerts you when your website goes down or when text changes. [5]
It offers a free trial with no credit card required. [5]
Check whether its monitoring covers the services your startup depends on before you rely on it.
Codex Forecast for AI startup founders
Codex Forecast is made by the team that publishes this site, and it is an independent tracker that is not affiliated with OpenAI. [1] It gives a statistical estimate of when OpenAI will next reset Codex usage limits. [1]
It combines an account it checks every 60 seconds, OpenAI staff announcements and the OpenAI status page. [1] When a measured refill and an announcement disagree, it trusts the measured refill. [1] Each reset used in the forecast is listed with a link to where it was announced. [1] The forecast is a guess, and a wrong guess means the predicted reset timing does not match the later reset.
You can opt in to free emails that are sent when a reset actually happens. [1] It is free and needs no account. [1] The site and API share a snapshot that is cached for up to five minutes. [1]
Matching the tool to the job
To see what the team has spent, ccusage analyzes token usage and costs from coding agent command-line tools, using local data. [3]
To check whether OpenAI has a known problem, look at OpenAI Status, which states that it is not aware of any issues affecting its systems. [2]
To watch your own website for downtime, StatusGator has built-in website monitoring that alerts you when it goes down or when text changes. [5]
To check outages across many vendors through code, IsDown offers outage data from 6,320+ vendors via API. [4]
To estimate when Codex limits reset, Codex Forecast gives a guess. [1] Its named-day predictions are scored in public, misses included, so check that record before you rely on any date it gives. [1]
To feed reset data into your own dashboard or script, Codex Forecast has a public API that needs no key and gives stats, reset history in pages, forecasts and information on whether the service is working. [1] The API has a published OpenAPI specification, a standard file that describes how the API can be called. [1]
Questions to ask before you choose
Which question matters most right now: the team's own usage, outages in the services the startup relies on, or when limits reset?
