signNow is an electronic signature that enables business to be conducted anywhere, anytime and on any device. signNow offers the best ROI for SBM and mid-market thanks to its intuitive UI, transparent pricing, flexible configuration and the ease of API integrations.
Postproxy is a social media API for products that need more than publishing. Publish posts, manage comments, DMs and reviews, track post and profile analytics, and receive webhooks across major platforms. Built for SaaS products, automation workflows, and agents that need reliable social media infrastructure without maintaining every platform API themselves.
Built for developers and automators using n8n, Zapier, LLMs, or CI/CD, it turns publishing into predictable infrastructure.
Free plan available, scale as you grow.
MCP included!
SignNow PostproxyPostproxy's answer:
We were building a product for ads creation at scale with fancy templates management, different platforms with adaptive sizing. Then Nano Banana got released and made a product largely obsolete. Postproxy was basically a part of that product.
Postproxy's answer:
Postproxy is a production-grade social media API for SaaS products, AI agents, and multi-tenant platforms. It provides one API for publishing, comments, direct messages, reviews, analytics, webhooks, and OAuth account connections across Instagram, Facebook, Threads, LinkedIn, TikTok, X, YouTube, Pinterest, Google Business Profile, Bluesky, and Telegram.
Compared with publishing-only APIs and automation tools, Postproxy is designed for customer-facing products that require official platform integrations, explicit delivery statuses, automatic retries, profile-group isolation, predictable pricing, and infrastructure built for production workloads.
Postproxy's answer:
Postproxy combines production-grade publishing infrastructure, engagement, and analytics in one social media API. Every publishing request has an explicit status and human-readable failure reason, failed deliveries can be retried automatically, and the same platform also handles comments, direct messages, reviews, profile analytics, and webhooks.
Postproxy uses official platform APIs and OAuth flows, supports isolated profile groups for multi-tenant products, and provides integrations for n8n, Make, and Zapier, as well as an MCP server for AI agents.
Postproxy's answer:
Postproxy is primarily built for developers and product teams creating SaaS platforms, AI agents, marketing tools, and multi-tenant social media products. It is also used by agencies and automation specialists that manage social accounts for multiple customers.
Individual creators can use Postproxy, but the platform is optimized for software products and production workflows rather than manual social media management.

If you need just that, then definitely signnow (signnow.com). Source: about 3 years ago
Signnow.com might work but they are not a document editor, strictly speaking (BUT amazing good for placing fillable fields! sic!). Source: over 3 years ago
It's just that Brendan guy (someone from your work, I guess?) is using signnow.com as their e-signature and doc preparation solution (just check the domain/site manually, it is completely safe). Source: over 3 years ago
If you only need to add several fillable fields and that's it -- I'd go either with signnow.com or with pdffiller.com (they look different but this is the same, US-based vendor). Source: over 3 years ago
If you need people's signatures on those forms, I'd say signnow.com (they also have an integration with pdffiller because of the same vendor, and it's pretty neat!). Source: almost 4 years ago
