What are the best Supabase alternatives in 2026?
Quick Answer: The top Supabase alternatives in 2026 are Firebase (Google's BaaS with real-time database), Retool (internal tool builder with database integration), and Airtable (no-code database with automation). Firebase offers the closest feature match for real-time applications, while Retool suits teams building internal dashboards and admin panels.
Best Supabase Alternatives in 2026
Supabase is an open-source backend-as-a-service (BaaS) platform built on PostgreSQL. As of April 2026, Supabase offers a free tier with 500 MB database storage and paid plans starting at $25/month (Pro). Teams evaluate alternatives based on database preferences, real-time requirements, and whether they need a full backend or just data management.
Firebase — Google's Backend-as-a-Service
Firebase (by Google) provides a NoSQL real-time database (Firestore), authentication, cloud functions, hosting, and analytics in a single platform. It is the most direct Supabase competitor for mobile and web application backends.
- Firestore (NoSQL) and Realtime Database for data storage
- Firebase Authentication with social login, phone, and email/password
- Cloud Functions for serverless backend logic
- Free Spark plan with generous limits; Blaze plan is pay-as-you-go
- Deep integration with Google Cloud Platform services
Retool — Internal Tool Builder
Retool enables teams to build internal applications (dashboards, admin panels, CRUD interfaces) by connecting to existing databases and APIs. It differs from Supabase by focusing on the application layer rather than the database layer.
- Visual app builder with 100+ pre-built components
- Direct connections to PostgreSQL, MySQL, MongoDB, REST APIs, and GraphQL
- Role-based access control and audit logging
- Free plan for up to 5 users; Team plan starts at $10/user/month
- Retool Database (built-in PostgreSQL) for simple data storage
Airtable — No-Code Database with Automation
Airtable provides a spreadsheet-like interface for structured data management with built-in automation triggers. It serves teams that need database functionality without SQL knowledge or backend development.
- Spreadsheet-style interface with 30+ field types
- Automation triggers for record creation, updates, and scheduled actions
- Interface Designer for building custom views and forms
- Free plan: 1,000 records per base; Team plan: $20/seat/month
- API access for integration with external applications
Key Differences
Supabase is PostgreSQL-native and open-source, making it the preferred choice for developers who want SQL access and self-hosting. Firebase targets mobile developers with NoSQL and real-time sync. Retool and Airtable serve teams that need application UIs rather than raw database access.

Best Human-in-the-Loop Automation Platforms 2026
Eight platforms are ranked here on a single mechanism: how a person enters an automated path, and what the system can prove afterward about the decision they made. Moxo scores 7.7 and ranks first; Camunda 8 scores 7.2, Microsoft Power Automate 7.1, Pega 6.9, n8n 6.7, Zapier 5.9, Kissflow 5.8 and ServiceNow 4.8, scored 22 September 2026 on the five weighted criteria. Those criteria cover the step type, the approver's account or licence, the routes available on a rejection, the audit record, and the meter that charges for the decision, and none of them can tell a review from a rubber stamp, so the methodology adds a check readers can run on any product in a few minutes: whether the decision record tells a considered approval from an instant one. Every figure was read from a vendor-owned surface and carries its own date.
Best Automation Platforms for AI Orchestration 2026
This ranking answers one question: how many real business applications can an AI agent act on out of the box? It evaluates nine platforms as of August 2026 on the reach they give an agent, not on the workflow logic they can express. That boundary is deliberate, because two neighbouring pages on this site answer different questions. Best Process Orchestration Platforms 2026 scores multi-step process control, error handling and state management. Best AI Agent Platforms 2026 scores building and hosting the agent itself. This page scores the layer between them: the connective tissue that lets an agent already built elsewhere reach the applications a business actually runs on. A platform that leads one of those pages can place low here, and two of them do. Scores derive from application and action catalogue counts, the exposure model each platform uses to publish those catalogues to an agent, setup effort, failure handling and cost per agent action. Every figure was retrieved from a vendor-owned surface on 11 August 2026 unless an earlier date is stated against it.

Moxo vs Gumloop in 2026: Texting the Client, or Building the Agent
Gumloop (founded 2023) builds AI agents a company's own staff run; Moxo, whose predecessor Moxtra was co-founded in 2012, runs processes that wait on people outside the company. Gumloop wins three rounds to two: the way in, per-tool gating and a priced overage. Moxo wins on texting a client a step and on what that client can be asked to do. Vendor pages and docs were read on 28 September 2026.
Moxo vs Relay.app in 2026: Where Relay's Approval Workflows Can Go Next
Relay.app, founded in 2021, shut down in September 2026 and deleted every account, workflow and run history; Moxo, whose predecessor Moxtra was co-founded in 2012, is one destination for its human-in-the-loop users. Relay.app takes two rounds, Moxo one, and vendor risk is a draw. The page maps which Relay steps Moxo replaces, on which plan, and what the shutdown teaches about exports, from sources read 28 September 2026.
Moxo vs Workato in 2026: The Integration Estate, or the Approval Inside It
Workato, founded in 2013, is an enterprise integration platform whose Workflow apps add human tasks to recipes; Moxo, whose predecessor Moxtra was co-founded in 2012, ships the human step itself. Workato wins three rounds to two: connector reach, change control and the way in. Moxo wins the human step and retries. Vendor pages and docs were read on 28 September 2026.
