Development and code

Languages, frameworks and code tools solve different constraints. A team benefits from choosing what it can test, update and hand over instead of accumulating technology.

Pick one function and prototype its normal path, failure state and update process. Check that a second person can explain the code, dependencies and deployment.

Browse the resources
Editorial method

A directory made to be useful, not merely long.

Each entry has a clear role and an official destination. The catalogue avoids link farms, copied descriptions and artificial rankings.

01

Official foundations

Standards bodies, official documentation and public authorities are used as primary reference points.

02

Professional tools

Established services are grouped by actual use: building, hosting, measuring, securing, publishing or promoting a website.

03

Independent reading

Inclusion is editorial and unpaid. A listing does not imply a partnership or guarantee.

Before choosing

Compare on three practical questions

Development and code
CriterionQuestion to resolve
CompatibilityDo versions, licences and environments fit the existing project?
MaintenanceWho can fix a defect, update a dependency and rerun tests?
DeliveryCan the code be built and deployed reproducibly?

Keep a short decision record: requirement, source, observed result and unresolved point. Test the same task with each candidate instead of comparing marketing lists of features.

Development and code

Languages, frameworks and code tools solve different constraints. A team benefits from choosing what it can test, update and hand over instead of accumulating technology.

Questions to check
  • State the need each dependency solves.
  • Check documentation, compatibility and update procedure.

A practical use : Pick one function and prototype its normal path, failure state and update process. Check that a second person can explain the code, dependencies and deployment.

What this cannot prove : Stars or popularity cannot replace fit with the team and the actual requirement.

Examples : PHP · Node.js

Editorial scope and third-party websites

This non-exhaustive directory was last reviewed on 30 August 2026; its links were checked on 25 September 2026. Some websites restrict automated checks. It contains external links to independent websites. Their availability, content, prices, cookies and terms may change. Française du Numérique does not control them and receives no commission for their inclusion.

Directory questions

Selection, independence and updates.

The editorial selection prioritises primary and official sources, established standards bodies, widely used professional tools, specialised media and active communities that are directly relevant to creating, operating, securing or promoting websites. An entry should have a clear purpose, an identifiable publisher and an official destination. The catalogue is independent, non-exhaustive and does not attempt to rank every available provider. Inclusion may be reconsidered when a resource closes, changes purpose, becomes misleading or no longer offers enough practical value. Review dates indicate when the catalogue was last checked as a whole, not a guarantee that every external page remains unchanged afterwards. Visitors should therefore confirm current pricing, terms, security and suitability on the third-party website before relying on a service.

No. A directory entry is a practical reference, not a certification, partnership, security audit or commercial endorsement. The listed organisations remain responsible for their products, content, prices, availability, cookies, personal-data practices and contractual terms. A resource may be useful for one project and unsuitable for another because requirements, jurisdiction, budget and technical capacity differ. Française du Numérique does not receive a commission for inclusion in this editorial directory. Before creating an account, purchasing a service or transferring data, visitors should review the official documentation, current terms, support arrangements, export options and relevant independent evidence. When the decision carries legal, financial or security consequences, an appropriately qualified assessment may also be necessary.

Yes. The search field checks resource names and editorial topics, while filters narrow the catalogue by category, geographical origin and resource type. Filtering and sorting take place locally in the browser, so the text entered in the directory search is not sent to a separate search provider. Combining several filters may produce no result even when a useful resource exists in a neighbouring category; in that case, remove one filter or try a broader term. The catalogue descriptions are deliberately concise and cannot represent every feature offered by a third party. Open the official website to confirm capabilities, documentation and current conditions before making a decision.

Use the contact page and provide the resource name, official URL, publisher, relevant category and a short explanation of its value for web professionals or project owners. For a correction, identify the entry and the information that appears inaccurate or outdated, ideally with a primary source. Suggestions are reviewed before publication and may be declined when the destination lacks a clear publisher, duplicates an existing entry, is primarily promotional, creates avoidable risk or falls outside the directory scope. Submission does not guarantee inclusion or a particular position, and paid placement is not offered through this editorial process.
