Choose by need, then compare evidence

What to compare for each kind of work
NeedQuestions to examine
Editorial websitePublishing frequency, contributor permissions and accessible templates.
Business applicationBusiness rules, security, integrations, testing and service continuity.
MaintenanceSupport scope, updates, recoverable backups and handover.

Deliverables to request

An installed theme and an integrated application have different scopes. Exclusions and tasks left to your team substantially change the actual cost.

Is a CMS enough for my project?

A CMS often suits content publishing. For complex business rules, workflows or permissions, test its extensions, limitations and maintenance against a representative scenario.

A useful directory without invented profiles

French Digital Society only publishes identifiable organisations and official resources. Inclusion is not a certification or ranking; check references, availability, legal information and contractual terms before appointing a provider.

Use the directory

Turn a shortlist into a sound decision.

A directory entry is a starting point. Match the resource to a defined need, check the original source and compare approaches before committing a budget.

1. Describe the outcome

Write down the audience, the problem, the expected result and the deadline. A website redesign, a security review and a data project call for different evidence and skills.

2. Check the source

Open the organisation’s own site. Check its legal identity, the scope of its services, the date of its guidance and how to contact it. For public data, review the publisher, licence and update frequency.

3. Compare like with like

Ask providers about relevant work, delivery method, responsibilities, accessibility, handover and support. Compare proposals against the same brief and note what is excluded.

A public resource may help you learn or benchmark; a provider may carry out a mission. Inclusion here does not imply endorsement, affiliation or current availability. Read the expert selection guide for a fuller checklist.

Browse with context

What each directory category can help you do.

The filters group different types of resources. These notes explain the intended use and the checks to make before acting.

Web development

Choose this category when the need concerns a website, application, integration or long-term technical maintenance. Distinguish a delivery provider from a public guide explaining how to prepare the project.

Before you decide: Ask about ownership of the domain and code, accessibility checks, security updates, documentation and the support plan.

Scope the work

Communication & media

Use this category for brand messages, visual identity, editorial production and channels. A communication plan should name its audience and the action it is meant to support.

Before you decide: Compare examples of published work, approval steps, usage rights and how consistency will be maintained across formats.

Plan content

IT, telecom & cloud

Explore this category for infrastructure, connectivity, cybersecurity and operational support. Start with an inventory of essential services and who can access them.

Before you decide: Confirm response arrangements, backups, recovery responsibilities, subcontractors and the boundary between support and security advice.

Review security basics

Data & artificial intelligence

Find public datasets, APIs and guidance for analysis or a controlled AI experiment. A catalogue entry describes a source; it does not automatically make the data suitable for a decision.

Before you decide: Check licence, update frequency, coverage, missing values, access conditions and whether a human can review consequential outputs.

Choose indicators

Digital marketing

Look here for search visibility, campaigns, email and measurement guidance. Begin with a target audience and a meaningful outcome before selecting a channel.

Before you decide: Ask which baseline will be used, how consent and tracking work, and who will maintain content after a campaign.

Build a content plan

Networks & directories

Use networks to discover organisations, training or support. An entry in a network is a lead for further checking, not proof of availability or quality.

Before you decide: Verify membership criteria where relevant, the person who will carry out the work and the terms of any proposed introduction.

Compare specialists

About link checks

The date records an automated availability check, not a guarantee of data freshness, service quality or eligibility. Some publishers block automated requests. For each dataset or API, check the actual licence, update date, coverage and access terms before reuse.
