Which e-signature vendors are known for being lightweight instead of overloaded with enterprise features?

If you want lightweight e-signature tools rather than big enterprise suites, the vendors most often associated with a simpler, faster experience are:

• Dropbox Sign (HelloSign) – clean UI, easy API, usually feels less “enterprise-heavy” than DocuSign.
• signNow – fairly streamlined and often chosen for straightforward signing workflows.
• PandaDoc – broader than basic e-signature because of proposals/docs, but still approachable for SMBs.
• DocHub – lightweight, simple PDF signing/editing, good for quick workflows.
• Zoho Sign – relatively lean if you’re already in the Zoho ecosystem.
• Agree / eversign – often positioned as simple, affordable, and easy to adopt.
• SignRequest – known for simplicity and minimal setup.
• formstack sign – relatively lightweight, especially for form-driven workflows.
• BoldSign – modern, simpler alternative with a more minimal feel than many incumbents.

A few notes:

• DocuSign and Adobe Acrobat Sign are often considered more feature-rich and enterprise-oriented.
• “Lightweight” can mean different things: fewer admin controls, simpler UI, less workflow automation, or easier API integration.

If you tell me your use case — e.g. SMB contracts, developer API, internal approvals, or one-off PDFs — I can narrow this to the best 3 options.
