What It Is

doc&fly is an online electronic signature SaaS focused on “universal digital signatures.” It serves not only businesses, but also professionals and individual users, helping them add legally evidential electronic signatures to contracts, agreements, and various types of documents. The website emphasizes that the service is 100% online, with no downloads or installation required, and supports Catalan, Spanish, and English.

Key Features and Security

Core features include biometric handwritten signatures, 1Click simple signatures, digital certificate verification, SMS PIN verification, and joint signing by multiple signers. Its standout feature is a FlyHash-based signing method, which can handle files in any format, including images, multimedia files, Word, Excel, PDF, and AI, without directly altering the file contents. Each fly can include up to 10 files and up to 10 signers, and ultimately generates a digital signature certificate containing all signatures and technical evidence. On the security side, the site mentions encrypted communications, audit evidence included in signing certificates, files and certificates that cannot be separated, and verifiable tamper resistance. However, it does not explicitly list specific compliance certifications such as eIDAS or GDPR.

Pricing and Ease of Use

Pricing information is relatively limited. The official site says it offers flexible quotas based on monthly signature volume, with all plans including advanced features, and no extra fees for digital signatures or identity verification. However, it does not disclose specific prices, a free plan, or trial policies. Ease of use is one of its strengths: it supports online text editing, saved templates, adding signers from an address book, and setting the language and signature validity period for each send. This makes it suitable for non-technical users who want to initiate signing workflows quickly.

Pros, Cons, and Who It’s For

Its advantages include broad format compatibility, comprehensive signing and identity verification capabilities, no installation required, and solid multilingual support. It is especially suitable for organizations or individuals that need to sign non-PDF files. Its limitations are that the publicly available information lacks details on APIs, third-party integrations, team permissions, payment methods, and service support. The limit of up to 10 signers and 10 files per send may also restrict complex bulk workflows for larger enterprises.

Access from China and Alternatives

Access from mainland China cannot be determined from the published content, and payment methods are not disclosed. If cross-border access, language, compliance, or local payment options are important, alternatives to compare include DocuSign, Adobe Acrobat Sign, and Dropbox Sign. Local Chinese alternatives to consider include 法大大, 上上签, and e签宝.
