FiveM Script Compatibility Checklist for Any Framework

“Supports ESX, QBCore, Qbox, and standalone” is a starting claim, not a complete compatibility answer. A script also depends on framework versions, inventory, target, menu, notifications, database shape, identity model, and event conventions. This checklist helps teams evaluate fit before purchase or installation without turning the decision into another framework comparison.

The scene shows integration context; verify the selected resource's current supported versions and APIs.

Create a stack manifest

Record exact framework build or fork, database adapter, inventory, target, menu, progress, notification, voice, phone, banking, garage, keys, fuel, door lock, and zone libraries. Include custom changes to player, job, item, or owned-vehicle schemas. “QBCore” alone does not reveal whether an export, metadata field, or table matches.

For the candidate, identify required and optional dependencies, resource names, start order, exposed configuration, bridge files, events, exports, callbacks, SQL migrations, and protected files. Use the Asset Escrow buying guide when source access is limited.

Practical criteria

• Supported framework versions are explicit, not merely logos.
• Character IDs, jobs, grades, items, accounts, and vehicles map correctly.
• Dependency versions and resource names match installed packages.
• Server events validate permission, distance, state, and values.
• Database migrations do not overwrite existing tables or columns.
• Adapters are isolated so core code does not need repeated edits.
• OneSync and routing behavior are documented where relevant.
• Updates preserve configuration and provide migration notes.

Browse script categories only after writing non-negotiable requirements. A feature-rich resource that assumes a different inventory or identity model may cost more integration time than a focused alternative.

Staging workflow

Clone a sanitized configuration and schema into staging. Back up before reviewing and applying vendor migrations through your normal process. Start declared libraries, framework, adapters, then the resource. Test default behavior before changing code.

Build a small matrix: create/load character, allowed and denied job grades, required item present and absent, sufficient and insufficient funds, normal and routed instance, reconnect, resource restart, and server restart. Watch server and client logs. Confirm each money or inventory mutation happens once.

Add one custom adapter at a time. Keep normalized internal functions—get character ID, get job, remove item, charge account—between the resource and framework. This limits future migration work. The installation help covers deployment basics; the Jobs Creator can assist with supported job configuration.

Build a contract and failure matrix

For every adapter, write the input, authoritative source, expected output, failure result, and side effects. A charge-account contract should identify account types, accepted amount precision, insufficient-funds behavior, transaction reference, and whether a retry returns the original outcome. An inventory-removal contract should specify metadata matching, slot behavior, quantity boundaries, and what happens when the item disappears between check and removal.

Test framework lifecycle moments, not just an already loaded character. Exercise new character creation, normal load, job change, duty toggle, inventory replacement, reconnect, multicharacter switch, and deletion. Verify cached adapters refresh when identity or job changes and that late events from the previous character are ignored. For routed gameplay, test both the default world and an isolated property or activity instance.

Create controlled dependency failures. Start the candidate before one required library, stop the target or inventory resource during an action, make a database callback fail, and restart the candidate several times. The resource should either refuse to start with a precise dependency error or rebind once without duplicate targets, commands, callbacks, or money handlers. A generic infinite wait hides incompatibility and makes production recovery unpredictable.

Score each mismatch by severity and ownership. A configurable item name is low effort; a different character-key model, protected billing path, or destructive schema migration is high risk. Estimate adapter code, test cases, update exposure, and support dependency. Reject the package when a critical contract cannot be made server-authoritative or when every vendor update would require patching core files.

Before approval, retain a versioned test record containing stack versions, migrations reviewed, scenarios passed, known limitations, rollback steps, and the maintainer responsible for each bridge. Repeat the matrix after dependency or framework updates. Compatibility is temporary evidence tied to versions, not a permanent label earned by one successful startup.

Mistakes and troubleshooting

An export is missing. Check exact dependency version, resource name, start order, and fork API. Do not add arbitrary waits to hide a missing contract.

Items exist but the script cannot find them. Compare item name, case, metadata, inventory adapter, and server/client API.

A UI opens but actions fail. The frontend loaded while a server callback or database migration did not. Trace one action end to end.

Players can invoke restricted actions. Add server-side checks; hidden targets and renamed events are not authorization.

Updates erase changes. Move adaptations into documented config or bridge files and maintain a change record.

Framework auto-detection chooses incorrectly. Set an explicit adapter when supported and remove conflicting compatibility resources.

Decision checklist

• [ ] Exact stack versions and custom schema changes are documented.
• [ ] Required dependencies and protected/editable files are known.
• [ ] Identity, jobs, items, money, and vehicles map correctly.
• [ ] SQL was reviewed and staged with a rollback.
• [ ] Denied, failure, restart, and reconnect cases were tested.
• [ ] Mutations are server-authoritative and idempotent.
• [ ] Custom logic lives in maintainable adapters.
• [ ] Update and support paths fit the team.

Compatibility is a set of verified contracts. Buy or deploy only when those contracts match your stack or the required adapter work is understood and maintainable.
