SiteBleed

SiteBleed™ is an uptime monitoring platform built for e-commerce store owners, freelance developers, and web agencies who can't afford to discover downtime from an angry customer.

SitePing

SitePing is a web service for web agencies and freelancers who look after many client sites built on WordPress, Joomla, Drupal and PrestaShop. It runs in the browser, so there is nothing to install on your computer. The interface is available in English and Italian. SitePing looks at each site in two ways. From outside, our servers check the site like a visitor would. Inside, a light agent installed as a plugin or module reads what cannot be seen from outside. The agent opens no ports on the client's server, and requests are signed in both directions. Outside checks - Uptime and response time. A site counts as down only when probes in at least two regions see it down. - SSL certificate and domain expiry, weeks in advance. - DNS changes, sitemaps filled with spam pages, robots.txt files that block Google, and blacklists such as Google and Spamhaus. - Security headers, Core Web Vitals, HTML validation and broken links. Inside checks, with the agent - New administrators and role changes, as they happen. - Every core file compared with the official release of the installed version. - PHP hidden in upload folders, fatal PHP errors, and admin logins from new IP addresses. - Installed versions with known vulnerabilities. - 193 configuration checks written for each CMS, from Super Users without two-factor login to database backups left in the site folder. Active Shield Some clients still run Joomla 3.10.12, Joomla 4.4.14 or PrestaShop 1.7.8.11, which no longer get fixes. Active Shield applies official security fixes to these versions. If someone changed a file it would touch, it changes nothing and tells you which file. Backups The client's server compresses and encrypts the database and files with AES-256, then uploads them to European storage. From the second backup on, only changed files are sent, and a restore takes one pass. Backups are locked against early deletion, and you can choose to hold the decryption key yourself. Updates that roll back Before an update, SitePing takes a full backup and a restore point with files and database tables. It checks the home page and the pages you choose before and after. If something breaks, files and database go back to the previous version. This works today for WordPress plugins and themes and Joomla extensions. One-click admin access Open any client's admin panel with a single-use link that expires after 60 seconds. Every login is recorded on the platform and in the site's own log, and the site owner can turn the feature off. Alerts Email, Telegram, webhooks, Slack, Microsoft Teams, Discord, Google Chat and other channels. Only serious problems reach your inbox. Pricing You pay per site, per month, in blocks of 5 sites. The price per site goes down in brackets as the licence grows. A Free plan covers uptime for up to 50 sites, and a 30-day free trial needs no credit card. A free read-only audit of one site is also available.

What Are Recent G2 Reviews of Site Spy?

SiteVector

Every day, your site loses time nobody writes down. A truck sits at the gate for ninety minutes. A trade waits half a morning for an area that was not ready. Both were obvious to somebody at the time. Neither one was recorded anywhere it could be found again, so by Friday afternoon the report gets built from phone calls and whatever people can still remember. That is not a failure of effort. It is what happens when the only place the detail ever lived was in somebody's head. SiteVector is a daily record for construction sites. There are four parts to it. Flow captures deliveries at the gate. The slot it was booked into, when it actually turned up, when unloading started, when it left and what was waiting on it. Commit captures the work planned for the day and whether it happened. When it did not, the reason gets picked from a list rather than typed as a sentence. That constraint is the whole point, because a sentence can be read while a reason on a list can be counted. Vector watches programme health area by area rather than across the whole job, which is usually where pressure shows up first. Vault holds the lot and builds the shift diary, the weekly reports and the full export. Nobody sits down to compile any of it. When the site closes, the day locks and seals. Changes are still allowed afterwards and every one carries who made it, when and why. So the record is not frozen. It just cannot be quietly rewritten. The judgement stays human throughout. SiteVector does not score anybody, decide who was at fault or guess what happened. It records what the people who were there put in. It runs in a browser. Nothing to install, nothing to integrate and a project is live in under five minutes. Hosted in Australia. Sixty days on a project you are already running, with no card.
