Alternative to La Poste Signature électronique: Certyneo in comparison
The Post Office offers two electronic signature offerings: the Digiposte integrated offer (digital safe) and the Professional Electronic Signature offer. Both comply with eIDAS and are hosted in France, but they remain large account oriented and lack flexibility for self-employed, TPE and tech teams who want an API.
No free plan at the Post Office
The E-Signature offer from La Poste starts at €9.90/month without a free plan or extended trial.
Limited API and opaque tariffs
The access to the La Poste API is reserved for quotation contracts.Certyneo has a public REST API documented from the Standard plan at €19/month, with webhooks and SDK.
Interface in French only
The La Poste signature interface is only available in French blocking if you work with international clients or partners.
Equal sovereignty
Both are players under French law, outside the Cloud Act, so the choice is made on the basis of features and pricing, not sovereignty.
The Commission also notes that the Commission has not yet decided whether the aid is compatible with the internal market.
