An AI agent builder runs models that allow a set amount of usage, so a used-up limit stops an agent mid-task. The tool that helps depends on the question: whether the service is up, how much was spent, or when a limit comes back. OpenAI Status reports whether OpenAI systems have known issues. [^1] ccusage analyzes coding agent token usage and costs from local data. [^2] Claude Code Usage Monitor monitors usage with predictions and warnings. [^3] Codex Forecast gives a guess of when OpenAI will next reset Codex usage limits, not a promise. [^4] | Option | What the tool does | Price as stated | |---|---|---| | OpenAI Status | Lists Codex at 99.95% uptime across 4 components. [^1] | not published | | ccusage | Analyzes coding agent token usage and costs from local data. [^2] | not published | | IsDown | Provides outage data from 6,320+ vendors via API. [^5] | Starter, $27 per month, or $22 per month when paid annually. [^5] | | StatusGator | Rated 5.0 on Capterra, GetApp, and Software Advice. [^6] | not published | | Claude Code Usage Monitor | Monitors Claude Code usage with predictions and warnings. [^3] | not published | | OpenAI Usage Dashboard | not published | not published | | Codex Forecast | Guess of the next Codex limit reset, not a promise. [^4] | Free, no account required. [^4] | ## What AI agent builders need from AI usage limit trackers An agent builder who runs coding agents against a model has three limits to track. First, how much of an allowance a project has spent. Second, whether the service is up when an agent needs it. Third, when a used-up limit resets so the agent can run again. Those are different questions, and they need different tools. Usage tools read what you have spent. Status tools report whether a service is having trouble. A reset tracker tries to say when limits refill. The three limits to track are your own spend, service outages, and reset timing. Some tools read data on your own machine, and some watch public status pages. Some charge by plan, and some are free. A builder may run agents for more than one model, so check which model a tool covers before you rely on it. A tool that covers many services may be more than one builder needs, and a tool built for one purpose may not cover the others. Check whether a tool reports your own usage, outages, or reset timing, because none of the three stands in for the others. For Codex, the reset time is a guess, and Codex Forecast gives the estimate. [^4] The sections below say what each source states and nothing more. ## OpenAI Status for AI agent builders Its page reports it is not aware of any issues affecting its systems. [^1] It lists Codex at 99.95% uptime across 4 components. [^1] The APIs figure is separate from the Codex figure: APIs had 99.96% uptime across 13 components over Jul 2026 to Oct 2026. [^1] For a builder, this figure reports API uptime, not the outcome of any single agent run. For your own usage or a reset date, check whether the page gives it. ## ccusage for AI agent builders ccusage analyzes coding agent token usage and costs from local data. [^2] It tracks and displays cache creation and cache read tokens separately. [^2] It tracks usage within Claude's 5-hour billing windows and monitors the current window. [^2] Because it reads files on your own computer, check whether it counts the model and sources your agents call before you trust the totals. ## IsDown for AI agent builders Its Outage Data API provides outage data from 6,320+ vendors via API. [^5] The Starter plan costs $27 per month, or $22 per month when paid annually. [^5] IsDown refunds in full if you cancel within 10 days of subscribing. [^5] Check whether OpenAI and Codex are among the services you need before relying on it. ## StatusGator for AI agent builders StatusGator is rated 5.0 on Capterra, GetApp, and Software Advice. [^6] It has built-in website monitoring that alerts on downtime or text changes. [^6] It offers a free trial with no credit card required. [^6] Check whether it monitors the specific services your agents depend on. ## Claude Code Usage Monitor for AI agent builders Claude Code Usage Monitor monitors Claude Code usage with predictions and warnings. [^3] It supports reset-aware forecasting and pace calculations. [^3] It can be installed from PyPI using uv. [^3] It is built around Claude Code sessions, so check whether it fits agents that call Codex. ## Codex Forecast for AI agent builders Codex Forecast is made by the team that publishes this site. It gives a statistical estimate of when OpenAI will next reset Codex usage limits. [^4] It combines an account it checks every 60 seconds, OpenAI staff announcements, and the OpenAI status page. [^4] When a measured refill and an announcement disagree, it trusts the measured refill. [^4] Each reset used in the forecast is listed with a link to where it was announced. [^4] Because it is a guess, the predicted reset can differ from the reset that actually happens. You can opt in to free emails that are sent when a reset actually happens. [^4] It is free with no account. [^4] It is an independent tracker and is not affiliated with OpenAI. [^4] The site and API share a snapshot that is cached for up to five minutes. [^4] ## Matching the tool to the job To see how much usage an agent build has spent, ccusage reads local usage data and reports token usage and costs. [^2] Claude Code Usage Monitor monitors Claude Code usage with predictions and warnings. [^3] To see whether OpenAI has a known problem, OpenAI Status reports on its systems. [^1] StatusGator has built-in website monitoring that alerts on downtime or text changes. [^6] IsDown offers outage data from 6,320+ vendors via API. [^5] To estimate when Codex limits reset, Codex Forecast gives a guess. [^4] Its named-day predictions are scored in public, misses included. [^4] The published information does not include an accuracy figure, so the hit rate and error figure are not yet known. To check the health of a service your agents depend on, StatusGator alerts on downtime or text changes. [^6] To build reset data into your own tools, Codex Forecast has a public API that needs no key and gives stats, reset history, forecasts, and service information. [^4] The API has a published OpenAPI specification. [^4] To compare monitoring options without paying, Claude Code Usage Monitor can be installed from PyPI using uv. [^3] StatusGator offers a free trial with no credit card required. [^6] IsDown refunds in full if you cancel within 10 days. [^5] ## Questions to ask before you choose Which question do you need answered: your own usage, service outages, or reset timing? Which model does your agent call? Some tools read local usage data from coding agent CLIs, and some watch public status pages. ccusage reads local usage data. [^2] Claude Code Usage Monitor covers Claude Code. [^3] Check which model each tool reports before you rely on it. How fresh does the data need to be? Check how each source updates its numbers. How much can you spend each month? Some options are free and some charge by plan, so check each page before you commit. IsDown's Starter plan costs $27 per month. [^5] Do you want a tool that reads files on your own computer, or a website you open? Codex Forecast is a website with a public API. [^4] Do you work alone or with a team? Team features may matter only in the second case. Do you need a tool that covers Codex specifically? Check each source's list of services before you rely on it. ## Frequently asked questions ### Which tool estimates when Codex usage limits reset?
