Pro is $25 per month and includes 100,000 monthly active users and 8 GB of disk per project. Annual prices are not published. Budget for usage overages and optional compute: paid plans include $10 monthly compute credits, and extra projects start at $10 per month.
03Features and depth
Replit is the broader app-building product: its Agent can write and publish projects, and the platform bundles authentication, database, hosting and monitoring. Its feature list also includes an Infinite Canvas for exploring designs, AI integrations and model routing that the product describes as 65% lower average cost than its prior Max Mode. Enterprise controls include SSO/SAML, security screening and admin controls; Enterprise pricing is custom.
Supabase is a backend, not a prompt-to-published-app builder. Its core is a portable Postgres database, with authentication, Row Level Security, file storage, REST APIs, Edge Functions and realtime features. It also offers tools for vectors, scheduled jobs and message queues. The free tier has specific resource caps; Pro raises those limits, while usage overages are priced separately. Team costs $599 per month and includes SOC 2 and ISO 27001. Choose Supabase when the backend and database matter most; choose Replit when you want the AI to build the app as well as provide infrastructure.
04Ease of use and learning curve
Replit is aimed at people who want to describe an app and let an AI Agent write and publish it, with hosting and other infrastructure included. That reduces the need to set up separate services, but the product’s pricing makes usage a consideration: Core includes stated Free Mode and model-credit allowances, while higher Pro-tier credit bundles cost extra.
Supabase gives developers a ready-to-use backend, including Postgres, authentication and APIs, but it is not presented as a no-code app builder. You still need an app to connect to the backend and decisions about database structure, access rules and usage limits. Its free tier is a practical starting point for experiments, but inactive projects pause after one week. For guided app creation, lean Replit; for control over a Postgres-backed backend, lean Supabase.
Questions people ask
Is Supabase the best option?
It is a strong fit if you need a portable Postgres backend with authentication, storage, APIs and realtime features. It is not the better fit if your priority is having an AI Agent write and publish the whole app; Replit is built for that broader workflow.
Is anything better than Replit?
That depends on what you need. Supabase is a more direct choice for a portable Postgres backend, with a free plan and published resource limits. Replit is the closer fit when you want an AI Agent to build and publish an app with hosting and infrastructure included.
Which is good, Supabase or Firebase?
The information here covers Supabase and Replit, not Firebase, so we can’t make a sourced feature or price comparison with Firebase. Between these two, Supabase is the backend option; Replit is the AI app-building option with hosting and infrastructure included.
Do any big companies use Supabase?
The published product and pricing information does not name large-company customers, so we can’t verify that here. It does list Team features such as SOC 2 and ISO 27001, while Enterprise offers custom pricing, technical account management, uptime SLAs and 24/7/365 premium support.
