Comparison

AssetSonar vs osTicket

Two tools districts shortlist for device tracking and IT operations, compared the way a buying committee actually reads them: what each is, what each does well, and what to check before signing. We build Chalk, a third option in this space — that context is worth knowing as you read, and it is why every claim below carries its basis.

AssetSonar

EZO's IT-asset product, and the rare asset tracker that publishes a per-asset price and includes a genuine service desk at the higher tier — metered by the one number a 1:1 district has most of.

Pricing: Published per-asset rates, which is unusually transparent for this category. ITAM is $0.75 per asset per month; ITSM, which includes ITAM, is $1.08 per asset per month; Advanced Software Asset Management is an add-on to either at $5 per asset per year, quoted as $0.42 per asset per month. Packages start from 100 assets, with volume-based discounts stated for 1,000+ assets and Enterprise arrangements by conversation. Agents are unlimited on both plans — EZO's own pricing copy calls out not capping your team with an artificial seat limit. No free tier and no published education discount.

Where AssetSonar is strong

  • It publishes real per-asset prices instead of gating every number behind a demo — $0.75 per asset per month for ITAM and $1.08 for ITSM — which makes a district budget line something you can build without a sales call.
  • Unlimited agents on both plans, so adding technicians, building secretaries or a summer help-desk aide never changes the bill.
  • The ITSM tier is a real service desk, not a ticket list: request and incident management, problem and change management, a service catalog, multi-channel intake, automated routing, multi-step approvals, SLA policies with business hours and escalation, a knowledge base and a self-service portal.
  • Custody features deeper than most trackers — check-in and check-out, automatic checkouts, automatic custody transfer, reservations and an availability calendar.
  • Genuine discovery breadth for a commercial tracker: agent-based discovery, network discovery, MDM integrations, barcode and QR scanning, and RFID tagging.
  • Procurement and service done properly — purchase orders and requests with multi-tier approvals, vendor management, warranty integration, service triage, and scheduled and recurring maintenance with automated reminders.

What to check before you buy

  • The meter is your fleet. At a per-asset rate, a 1:1 district is billed on the number it has most of, and every Chromebook you add is a line item forever.

    Basis: Vendor pricing page quotes ITAM and ITSM as per-asset-per-month rates.

  • Packages start at 100 assets, so the smallest sites pay a floor rather than what they use.

    Basis: Vendor pricing FAQ: AssetSonar packages start from 100 assets, with volume-based discounts for higher volumes.

  • The help desk is the upgrade. SLA management, the service catalog, the self-service portal, the knowledge base, problem and change management and the CMDB are all marked ITSM-only in the vendor's own comparison table — the difference between $0.75 and $1.08 per asset per month.

    Basis: Vendor's published ITAM-versus-ITSM plan comparison table.

  • Software asset management is a third line item on top of either plan, at $5 per asset per year.

    Basis: Vendor pricing FAQ describes Advanced SAM as an add-on available with both ITAM and ITSM plans.

  • No SIS or rostering integration — no OneRoster, Clever, ClassLink, PowerSchool, Infinite Campus or Skyward anywhere in EZO's connector catalog, which covers MDM, identity and procurement systems.

    Basis: Absent from EZO's published integrations listing for AssetSonar.

  • No student, guardian or enrollment concepts. Checkout is employee custody, so a transfer, a withdrawal or grade rollover is invisible unless someone edits the record.

    Basis: The product's data model tracks assets and users; the custody features are documented as employee check-in and checkout.

  • No parent e-signature on a device agreement, no student fee assessment, no family balances, and no funding-source or grant dimension for ESSER, Title or E-Rate reporting.

    Basis: Absent from EZO's documented feature set and plan comparison.

  • Device connectors are ingest-oriented. The MDM integrations import device state into AssetSonar; nothing pushes a reviewed set of changes back, so an OU move or disabling a stolen Chromebook stays manual in Google Admin.

    Basis: EZO's integration listing describes MDM connectors as importing device data, with no write-back workflow claimed.

osTicket

The open-source ticketing system a lot of school districts already quietly run — GPL2, free, self-hosted on a LAMP stack, and very good at tickets. The comparison with Chalk is about scope, not cost.

Pricing: The community edition is free and open source under GPL2, downloaded and self-hosted on your own server — there is no seat count, no ticket cap, and no licence to renew. Requirements are an Apache or IIS web server, PHP 8.2–8.4, and MySQL 5.5 or greater. A commercial hosted edition is sold separately through SupportSystem with a 30-day trial and no credit card required; that cloud offering publishes no pricing on the download page, so a hosted figure requires contacting them.

Where osTicket is strong

  • Genuinely free and genuinely open source under GPL2 — no seat cap, no ticket cap, no trial clock, and the source is yours to read, patch, and keep running.
  • One of the longest-running and most widely deployed ticketing systems anywhere, which means a large body of community documentation, forum answers, and people who have solved your problem already.
  • A deep, well-worn ticketing core: custom fields and forms, custom columns and queues, ticket filters and routing, help topics, SLA plans, agent collision avoidance, assign/transfer/referral, auto-responders, internal tasks, and advanced search with CSV export.
  • A customer portal and knowledge base for self-service, so end users can check status and find answers without opening a ticket.
  • An official OAuth2 plugin covering Microsoft, Google, and Okta sign-in for both agents and end users, plus modern OAuth email authentication for system mailboxes — which matters now that basic auth is gone from Microsoft and Google mail.
  • A working plugin surface and developer documentation: S3 attachment storage, audit logging, two-factor authentication, password policies, an API, and published database ERDs.

What to check before you buy

  • No asset or inventory management at all. osTicket is a ticketing system — there is no device record, so a ticket cannot tell you which machine the student is holding, what its serial is, or whether it is under warranty.

    Basis: Asset and inventory management appear nowhere in osTicket's feature list or documentation index.

  • No 1:1 device circulation: no check-out to a student with a due date, no overdue workflow, no parent-signed agreement, no loaner pool, and no lost or stolen lifecycle — and no native mobile app or barcode scanning to run a rollout or an audit with.

    Basis: There is no asset model in the product for these workflows to attach to, and the documentation has no mobile application section.

  • No SIS or rostering integration — no OneRoster, Clever, ClassLink, PowerSchool, Infinite Campus, or Skyward — and no student, guardian, or enrollment concepts. Users are created by sign-in or import, not sourced from the system of record.

    Basis: No SIS connector exists in osTicket's plugin set or documentation.

  • No ChromeOS, Google Admin, Intune, or Jamf ingest, so nothing reconciles anything against what the fleet actually reports.

    Basis: No MDM connector appears in the plugin listing or documentation.

  • No repairs with parts stock, no student fee assessment or family balances, no purchase orders, no warranty tracking, and no funding-source reporting for ESSER, Title, or E-Rate money.

    Basis: All absent from the published feature list and documentation.

  • SSO is consumed, not issued, and SAML is not covered by an official plugin — the supported providers are Microsoft, Google, and Okta over OAuth2, with SAML available only through an unofficial community plugin on GitHub.

    Basis: osTicket's OAuth2 documentation names Microsoft, Google, and Okta; the SAML plugin in circulation is a third-party repository, not a vendor-maintained one.

  • Reporting is thin. There is a dashboard tab, but no reporting or analytics section in the documentation, so trend reporting past ticket exports usually means querying MySQL yourself.

    Basis: The documentation index has no dedicated reporting or analytics section.

  • You operate a LAMP stack, not an application. PHP 8.2–8.4 plus MySQL plus a web server means patching three moving parts, and a PHP major-version bump is a real upgrade project rather than replacing one file.

    Basis: Requirements published on osTicket's download page and repository.

The third option: Chalk

If you are weighing AssetSonar against osTicket, Chalk belongs on the same shortlist. It is the open-source K-12 IT stack: device inventory that fills itself in from Google Admin, Intune, and Jamf against a roster synced from your SIS, a 1:1 circulation desk with agreements and fees, repairs with parts and costs, a help desk that already knows who is asking, and a built-in SAML/OIDC identity provider.

  • Self-host it free forever under AGPL-3.0 — the entire feature set, one binary, your infrastructure — or use the hosted version, priced by fleet size with no per-seat or per-student fees and the price ladder published.
  • Built only for K-12: students, buildings, custody, funding sources, and ChromeOS auto-update expiration are native concepts, not custom fields.
  • Writes back to Google Admin as a reviewed diff — every OU move, disable, and deprovision previewed before it executes — and serves a OneRoster 1.1 API so other district systems can pull the roster from Chalk.
  • Fees are assessed and tracked without touching payment cards, keeping the asset system out of your PCI scope.

See all three on your own roster.

Chalk installs to a populated inventory in about 30 minutes. Self-host free under AGPL-3.0, or let us run it — priced by fleet size, never per seat.
