ShadowHare checks your web pages and APIs on a schedule, compares every capture with the last one, and emails you as soon as something changes, slows down or breaks, with the before and after side by side.
No card neededSet up in minutesCancel any time
No scripts to write. Add a job in the browser and ShadowHare does the watching.
Paste a URL, or an API endpoint with its method, headers and body, or send the page you're on from Chrome with the extension. The Wizard can load a page first and suggest the settings for you.
Check every 10, 30 or 60 minutes, or every 5 minutes on Business. API jobs go down to every minute.
Each check is compared with the one before. Past your sensitivity, you get an email with both versions, and it's logged.
Watch what your customers see, what your competitors publish and what your own APIs return, all in one place.
A real Chrome browser loads the page and takes a screenshot, which is compared with the last one.
Call an endpoint on a schedule and watch the response, not just whether it answered.
Every change, failure and slow response is emailed and logged, so nothing slips past.
See every check a job has run, search across all of them, and send the history to whoever needs it.
Business accounts get unlimited users, groups to organise jobs, and roles that decide who can do what.
Turn a job off without losing anything, and keep a record of what changed and when.
Sign in to the site in Chrome as you normally would, open the page you want to watch and click ShadowHare in the toolbar. The extension hands the page and your cookies for that site to ShadowHare, so each check sees the page as you do, signed in.
Install a small agent on a Linux machine or in Docker at any of your locations. Jobs set to capture from that location run through it, so they can reach intranet pages, internal APIs and device dashboards, and they come from your own internet address.
Business organisations get their own database and their own log indexes. Nothing is shared with another customer's.
Each business has a separate database and separate log storage indexes, and its screenshots are stored apart from everyone else's.
Cookies, API headers and request bodies are encrypted at rest and never sent back to the browser. Card details go only to Stripe.
Audit logs are kept for seven years on Business. Job logs and screenshots are kept for a stated time, then removed automatically.
Both plans start with a 14-day free trial. No card needed to start it, and nothing extra is billed during it.
For one person, with any email address.
For your organisation, on your own domain.

One page or one API endpoint that ShadowHare checks on a schedule. On Individual, your 10 can be any mix of visual and API jobs. On Business, 25 of each type are included.
Yes. A disabled job stops checking but keeps its screenshots and logs, and storing those is what you pay for. That's the point of disabling rather than deleting: you keep the history. Delete a job when you no longer need it.
Nothing breaks and you don't need to do anything. Each extra job is $1 a month and each extra agent $5 a month. They're added to your subscription the moment you create them and removed when you delete them, prorated to the day.
100 GB of screenshots and saved API responses is included for the whole organisation. Past that, each GB is $0.25 a month, charged on your daily average, so a busy week costs only for that week. Or choose to have the oldest screenshots removed to stay within 100 GB. Either way, every job keeps its newest screenshot, and your admins are emailed at 80% and 100%.
Each pack adds 5 jobs for $10 a month. Choose how many you want when you subscribe, and change the number on the Billing page at any time. The difference is prorated on your next invoice.
Individual is for one person, with any email address, and has no users or organisation settings. Business is for a company on its own email domain. Colleagues at that domain can join with an admin's approval, and you get roles, groups, site agents, faster checks and longer history.
Every account starts with 14 days free and no card. Individual trials get 10 jobs; Business trials get 25 visual jobs, 25 API jobs and 5 site agents. Subscribe whenever you're ready and carry on without a break.
Site agents come with the Business plan only, including its free trial: 5 are included, then each one is $5 a month. Individual accounts can't add them. An agent needs a Linux machine (a .deb or .rpm package, or a one-line install script) or Docker. The agent only makes an outbound connection on port 443, so no firewall changes are needed. Until you list internal addresses in its config file, it reaches only the public internet.
Yes. A visual job can carry the cookies of a signed-in session. The easiest way to add them is the ShadowHare extension for Chrome: sign in to the site, open the page and click Create a job or Wizard. A site's sign-in doesn't last for ever, so when it signs you out, send the page again to refresh the cookies. For pages only your own network can reach, use a site agent (Business plan).
You keep full access until the end of the period you've paid for. After that, captures stop and your data is kept for 45 days in case you change your mind, then deleted.
Try every feature free for 14 days. No card, no installation, and no sales call.
