Frequently asked questions
Everything teams ask before switching from StackOne to Apideck.
Both are modern unified APIs with hosted MCP servers, llms.txt, broad SDK coverage, and SOC 2 Type II. StackOne lists more total connectors (550+ vs 200+), now positioned as agent connectors with its legacy unified APIs no longer in active development, and prices with a platform fee plus usage credits. Apideck offers public per-consumer pricing with unlimited calls and connections, plus an integrations marketplace and customer-facing Vault UI that StackOne does not currently ship.
Both publish pricing publicly. Apideck charges per consumer (end customer connection) with unlimited calls per consumer. StackOne prices with usage credits (one tool or API call is one credit): Gateway Starter and OEM Core are free, Gateway Team is $600/month, and Enterprise is quote-only. Which model fits depends on whether your usage scales with customer count or with API call volume.
