Ceased operations in 2017. Shame, really; I liked the premise. Kept here for historical purposes.

"Webscripts respond to HTTP requests, making them easy to call from web and mobile apps. Webscripts have all the features you need, like password hashing and persistent storage, plus the full programmability of Lua. Many developer tools, such as GitHub and Stripe, offer webhooks as a way of delivering notifications. Webscripts are a fast and easy way to receive those webhooks. Our built-in request logging makes them equally easy to debug on-the-fly. Webscripts can also be activated on a schedule, providing a simple way to build monitoring or other automation. Webscript Easy integration with any gaming platforms."

Example: TicTacToe server:

Script /start:

local id = math.random(1, 100000)
local board = {}
for i = 1,9 do board[i] = '' end
local state = {board=board, players={X=request.form.secret}}
storage['game:'..id] = json.stringify(state)
return {id=id, state=state}

Script /join:

local pusher = require('pusher')
local id = request.form.id
local state = json.parse(storage['game:'..id])
if state.players.O ~= nil then
	return 403
else
	state.players.O = request.form.secret
	state.turn = 'X'
	storage['game:'..id] = json.stringify(state)
	pusher.send('<pusher app id>', '<pusher auth key>', '<pusher auth secret>',
		request.form.id, 'update', json.stringify(state))
	return state
end

Script /move:

local pusher = require('pusher')
function getwinner(board)
	local lines = {
		{1,2,3},{4,5,6},{7,8,9},	-- horizontal wins
		{1,4,7},{2,5,8},{3,6,9},	-- vertical wins
		{1,5,9},{3,5,7}						-- diagonal wins
	}
	for i,line in ipairs(lines) do
		local winner = nil

			winner = winner or board[index]
			if board[index] == '' or board[index] ~= winner then
				winner = nil
				break
			end
		end
		if winner ~= nil then
			return winner

	end
	return nil
end
function isfull(board)
	for i,v in ipairs(board) do

	return true
end
local state = json.parse(storage['game:'..request.form.id])

	return 403
