Nylon vs Zernio
Zernio is a wider platform — social, messaging, voice, SMS and ads behind one bill — and on some of that surface they are further along than we are. Nylon is the opposite bet: social only, one predictable line on the invoice, and bring-your-own-keys treated as a documented feature rather than a footnote. If you want a focused social API whose price you can predict, this is the trade.
Where each one is stronger
Every claim in the Zernio column is taken from pages they publish, checked in September 2026. Rows where they are ahead are marked as such.
| Nylon |  Zernio | |
|---|---|---|
| Bring your own OAuth app | A documented feature: every provider, from the free tier, with a guide | Supported, but mentioned once in their entire documentation — an aside in a rate-limit note. No guide, and nothing on their site or pricing page |
| Predictable bill | One line: connected accounts. No request metering of any kind | Per-account, plus X API passed through per request ($0.005–$0.20), ads metered per active ad, SMS per segment |
| Surface area | Social only — one contract, nothing to learn or pay for that you will not call | Social, messaging, voice, SMS and ads across 16 channels and 7 ad networks |
| Price per connected account | Graduated $6 / $3 / $1, first two accounts free | Graduated $6 / $3 / $1, first two accounts free |
| Managed OAuth apps | Every network runs on our apps — nothing for you to register | Platform apps provided |
| Data residency | United States (Virginia). Operated by an EU-established company | Not stated on their site |
| Analytics | In build. Nothing returns analytics today | Live across their platforms, included |
| Inbox coverage | Telegram | DMs, comments and reviews across their platforms |
| Webhooks | Live — post outcomes and accounts needing re-auth. HMAC-signed, retried for a day, with a delivery log | Live — post status, messages and comments |
| Client libraries and agent tooling | REST, an OpenAPI spec and a live MCP server with fourteen tools | Eight SDKs, a CLI and a live MCP server |
| Security certifications | GDPR, DPA and subprocessor list published | SOC 2 and GDPR paperwork via a trust portal |
| Enterprise access control | Not offered | SAML SSO, SCIM, MFA, audit logs and role-based access |

Choose Nylon if
- Your users must authorise your OAuth app, and you want that documented rather than buried
- You want one predictable line on the bill, not per-request metering that moves with usage
- You want a social API, not a platform spanning voice, SMS and ads you will never call
- You would rather read one contract than eight SDKs across sixteen channels
Choose Zernio if
- You need analytics live today rather than soon
- You need an inbox beyond Telegram
- You want ads, phone numbers, SMS or WhatsApp behind the same billing
- You need SOC 2, SAML SSO or SCIM
We would rather tell you this than have you find out after integrating.
