Coupler.io vs Stackby

Coupler.io is a no-code data integration platform built by Railsware, a Ukrainian software product studio. It began as a Google Sheets add-on that imported data from Airtable and other apps, then grew into a standalone service that pulls data from business tools into spreadsheets, BI dashboards and warehouses on a schedule. Its core job is automated reporting for teams that do not have data engineers.

Coupler.io connects to more than 400 sources, including Google Ads, Facebook Ads, HubSpot, Shopify, QuickBooks and Xero, and sends data to Google Sheets, Excel, Looker Studio, Power BI, Tableau, BigQuery, Snowflake, PostgreSQL and Redshift. Between source and destination you can filter, aggregate, append and join data. Newer AI features let you build flows by chat, ask questions about your data and expose it to Claude, ChatGPT and other assistants through MCP servers. Plans scale by connected accounts, destinations, refresh frequency and rows.

It fits marketing agencies, finance teams and small businesses that report in spreadsheets or Looker Studio and want daily or hourly refreshes without code. Fivetran and Airbyte are stronger for warehouse-first data teams with large volumes, Hevo Data sits in between, and Supermetrics-style tools focus mostly on marketing data. Coupler.io is not built for complex transformations or real-time pipelines.

Buying tip: the free plan allows only manual refresh and 100 rows per run, so use the 7-day full trial to test real reports. Annual billing saves about 25%, and the Active plan removes row limits.

Stackby is a spreadsheet-database tool in the Airtable mould, combining the familiar grid of a spreadsheet with typed columns, linked records and multiple views. What sets it apart is a set of API column types that pull live data from services such as YouTube, Google Analytics, Facebook Ads and other APIs directly into table cells.

Tables can be viewed as grid, kanban, calendar, gallery and form views, and automations send notifications or update records when data changes. A template library targets marketers and agencies: content calendars, social media trackers, SEO keyword lists, CRM pipelines and campaign reports. API columns refresh metrics such as views, subscribers or ad spend on a schedule, and a REST API and Zapier integration connect Stackby to other tools. Plans are priced per seat: a limited free plan, then Economy, Business and Business Plus plans with more rows, API calls and automation runs.

Stackby suits marketers, content creators and small agencies who want a cheap, flexible database that enriches itself with live marketing data. It is less known than Airtable, with a smaller ecosystem of integrations and extensions, less depth in automation and interfaces, and slower performance on large tables. Airtable is the more powerful mainstream choice, SeaTable and NocoDB offer self-hosted alternatives, and Smartsheet suits project-heavy enterprises.
