PostLake vs Buffer
Buffer is a great dashboard for scheduling by hand — but if you want to post programmatically, its API is in beta and geared to personal use, with no agent tooling. PostLake is API-first: an open REST API and a hosted MCP server for 9 networks, from $13/month.

Create a key and post in minutes over plain REST. No waiting on beta access or app-review gates just to publish a post from your own code.
A hosted MCP server with 22 tools, so Claude, ChatGPT or Cursor can publish, schedule and read analytics by being asked. Buffer has no MCP server.
Buffer bills per connected channel — ten channels is about $50/mo before you post. PostLake charges usage-based credits, so connecting more accounts doesn't raise your bill.
Publish to many accounts in one call and get a single normalised shape back — one post id and a per-target result — so your code never branches per platform.
We'd rather be honest. Buffer is an excellent product for what it's built for:
Say you connect 10 channels and post to them from your own app or an agent:
| Scenario: 10 channels | PostLake | Buffer |
|---|---|---|
| How you're billed | Per post (credits) | Per channel (~$5/mo each) |
| Base cost for 10 channels | $0 extra to connect them | ~$50/mo before posting |
| Programmatic + agent access | Included | Limited / not agent-ready |
(Prices checked against buffer.com and Buffer's developer docs, July 2026 — Buffer's API terms are in flux, so verify current details before relying on them.)
Buffer has an API, but it's been limited for new third-party developers — the newer API is in beta and geared to personal keys rather than open third-party OAuth apps. PostLake gives you an open REST API with Bearer keys and OAuth, plus a hosted MCP server, from day one.
Buffer doesn't ship an MCP server or native agent tooling. PostLake ships a hosted MCP server with 22 tools that any agent connects to over OAuth, so it can publish, schedule and read analytics by being asked.
Often, yes. Buffer charges per channel (about $5/month each on Essentials), so ten channels is roughly $50/month before you post. PostLake charges usage-based credits and doesn't bill per connected account.
Not exactly — Buffer is a polished UI for scheduling by hand, and it's good at that. PostLake is an API and MCP server for developers and agents. Want a human dashboard? Buffer. Want to post programmatically or via an agent? PostLake.
