Postproxy Review (2026): Pricing, Features & Honest Verdict

Postproxy is one API for publishing, replying, and analytics across 11 social platforms. We found it replaces a stack of per-platform integrations with a single endpoint that handles OAuth, token refreshes, and rate limits for you. Best for developers building social features into a product. Price: free plan, then from $17/mo. Rating: 7.5/10.

What is Postproxy?

Postproxy is a unified social media API. Instead of integrating Instagram, TikTok, X, LinkedIn, and eight other platforms one at a time, each with its own auth flow, quirks, and breaking changes, you integrate Postproxy once. It converts your single request format into whatever each target platform expects, manages the OAuth dance and token refreshes, and handles rate limits with automatic retries.

It launched on Product Hunt in June 2026. The problem it solves is painfully familiar to anyone who has built social functionality: every platform has a different API, and they all change without warning. Postproxy abstracts that mess behind one interface covering publishing, comments, direct messages, and insights. For a small team, that is weeks of integration work and ongoing maintenance you do not have to own.

What Are Postproxy’s Key Features?

One API for 11 platforms

Postproxy supports Instagram, Facebook, Threads, TikTok, X, YouTube, LinkedIn, Pinterest, Bluesky, Telegram, and Google Business. You write your integration once and reach all of them. When a platform changes its API, Postproxy absorbs the change so your code does not break. That is the core value: you stop maintaining 11 fragile integrations.

Publishing plus two-way engagement

This is not just a scheduler. Postproxy handles outbound publishing and inbound engagement: replying to comments, responding to DMs, and managing reviews across every connected account through the same API. That makes it suitable for building real social inboxes and engagement tools, not only post schedulers.

Managed auth and rate limits

Postproxy handles the parts everyone hates. It manages OAuth, refreshes tokens before they expire, respects each platform’s rate limits, and retries automatically when calls fail. These are the things that quietly break in production at 2am, and offloading them to a dedicated service is the whole point of paying for an abstraction layer.

Predictable, explicit pricing

Every plan includes every feature. Tiers differ only by how much you publish and engage, not by which capabilities you unlock. Postproxy says it does not charge overage fees or silently drop posts, so you always know what will happen when you hit a limit. After years of opaque API pricing from the platforms themselves, that clarity is refreshing.

How Much Does Postproxy Cost?

Postproxy starts free and the first paid tier is $17 per month, or $12 if you pay annually. The Free plan gives 10 posts and 20 engagements a month across 2 profile groups, which is enough to test real workflows. Build at $17/mo lifts that to 120 posts and 240 engagements across 10 groups. Grow at $49/mo ($35 annual) makes posts and engagements unlimited with 20 groups. Scale at $99/mo ($79 annual) adds SSO and 50 groups, and Enterprise at $699/mo ($559 annual) goes up to 500 groups.

Against the main alternative, Ayrshare, Postproxy is competitive and arguably clearer. Ayrshare’s business plans start higher and meter by API calls and profiles in ways that can surprise you. Postproxy’s flat tiers with no overage are easier to reason about. The one jump that stings is Scale to Enterprise: going from $99 to $699 is a big step if you sit between 50 and 500 profile groups.

Who is Postproxy Best For?

Use Postproxy if you are building a product that needs to publish or engage on social platforms: a scheduling tool, a social inbox, a marketing dashboard, or an agent that posts on a user’s behalf. The unified API saves weeks of work and removes a permanent maintenance burden. The free tier lets you prove the integration before paying.

Skip Postproxy if you only manage your own brand’s accounts and never touch code, because a normal scheduling app like Buffer will serve you better. Also skip it if you need a niche platform it does not cover, since the value collapses if your key network is missing.

Best Postproxy Alternatives

Ayrshare is the closest competitor, a mature social API with broad platform coverage. It is more established but its pricing is higher and less predictable for growing teams.

Mixpost is a self-hosted, open-source social management tool. It is cheap to run if you have the infrastructure skills, but you maintain it and its platform integrations yourself.

Buffer is the alternative for non-developers. It is a polished end-user app for scheduling, not an API, so it fits teams managing their own accounts rather than builders.

Final Verdict: Is Postproxy Worth It?

Postproxy nails a real developer pain. Maintaining separate integrations for 11 social platforms is miserable and never-ending, and a single well-priced API that handles OAuth, rate limits, and breaking changes is genuinely valuable. The transparent flat pricing with no overage fees is a real selling point against incumbents that meter in confusing ways.

The caution is maturity and coverage. Postproxy is newer than Ayrshare, so you are trusting a younger service with the uptime of a feature your users will notice immediately when it breaks. Check that it covers the exact platforms you need and that its reliability holds under your volume. If both check out, it is an easy recommendation for any team building social features without wanting to babysit a dozen APIs.
