How we grade them
| 2.6GPAOpenSignGood | 2.6GPASignWellGood | |
|---|---|---|
| Value for money | CTeams is $19.99 a user a month billed yearly ($39.99 monthly), so about $60 a month for three. That's the dearer end of this category, for shared templates and your own storage. The free cloud plan covers 20 documents a month if you can do without sharing; self-hosting doesn't count. | B$30 a month for up to three senders on Business, billed yearly ($36 monthly). That's $10 a head for unlimited documents and templates, inside this category's cheapest quarter. A fourth sender adds $12 a month. |
| Free plan and trial | AThe free cloud plan has unlimited signatures and templates, 14 field types, signing order and completion certificates, with no cap a normal person would reach. Automatic reminders and the API are the paid bits. | CThe free plan is one sender, one template and 3 documents a month, with the API and the audit trail. Handy for the odd form, nowhere near 20 a month. There's no trial of the paid plans on record. |
| Features | CTemplates, signing order, expiry dates, decline, sealed completion certificates, plus API, webhooks, Zapier and embedded signing on paid plans. The gaps: custom branding needs Enterprise, there's no mobile app, and payment requests are still listed as coming soon. | BUnlimited documents, template links, bulk send, branding, conditional fields, data validation, signer attachments, in-person signing and 50 SMS credits a month on Business. Nothing in the listing shows a gap in the core signing job. |
| Ease of use | CNo store rating on record. The cloud version is a web app with templates to set up; hosting it yourself means following the self-host guide and running a server. | CNo store rating on record, and no phone app. It's a web app where you set up your templates and fields once, which is quick enough, but there's still setting up to do. |
| Platforms and integrations | BWeb only, with Zapier, Dropbox and Gmail, and an API, webhooks and embedded signing on paid plans. No phone app yet, so it's web with integrations. | BWeb only, with Close, QuickBooks Online, Xero and thousands more through Zapier, plus an API with 25 free documents a month on every plan, webhooks and an MCP server. |
| Best for | unlimited free e-signatures | small teams that want unlimited documents cheaply |
