6 free alternatives to Upstash

Supabase's free tier is centered on a dedicated Postgres database with unlimited API requests, 500 MB of database size per project, 5 GB egress, 1 GB file storage, and up to 500,000 Edge Function invocations. It also includes auth features, realtime, and unlimited dashboard team members, so it covers more of the app backend in one place. Compared with Upstash, it gives you far more room on API traffic and a broader backend surface, while still staying free. The tradeoff is that it is a different database model and free projects pause after one week of inactivity. Switch if you want a fuller backend platform rather than a Redis-compatible data layer.

• Beats Upstash: Unlimited API requests
• Falls short: Different database model than Upstash's Redis-compatible APIs
• Who should switch: Switch if you want a broader backend platform with more free API headroom and built-in auth, realtime, and storage.

Stackby's free tier gives you 5 editors, 50 read-only users, 20 stacks, 1,500 rows per stack, 2 GB of attachment space per stack, 100 internal automations per month, 2 linked API connectors, and 2 MB file uploads. It is built around spreadsheet-style tables, views, forms, and automation, so it works well when the problem is organizing data and workflow rather than serving low-latency app traffic. Against Upstash, it beats on collaborative workspace features and no-code database structure. It falls short on command throughput and server-side database behavior, since refreshes are manual and the product is not meant for Redis-style app infrastructure. Switch if your free need is more operational database workspace than backend datastore.

• Beats Upstash: Collaboration and no-code workflow features
• Falls short: No Redis-compatible backend or command throughput model
• Who should switch: Switch if you need a shared spreadsheet-style database with automations and connectors instead of an application data service.

Convex's free tier includes access for 1 to 6 developers, file storage, text search, vector search, crons, auth, Node.js actions, preview deployments, and a health dashboard. It also allows up to 40 deployments, 1,000 concurrent sessions, 16 concurrent queries, 64 concurrent actions, 1M function calls per month, 20 GB-hours of action compute, and several capped storage and egress allowances. That makes it a better fit for teams building a full TypeScript backend around app logic, not just key-value data access. It loses to Upstash on simplicity if you only need a Redis-compatible service, since Convex is a bigger platform to adopt. Switch if you want more free backend functionality around your app code.

• Beats Upstash: Full backend platform features such as auth, crons, and search
• Falls short: Less direct if you only need a simple Redis-compatible datastore
• Who should switch: Switch if you are building an app backend in TypeScript and want compute, search, and auth in one free plan.

Amazon DynamoDB's free tier includes 25 WCUs and 25 RCUs per month on standard tables, 25 rWCUs for global tables across two AWS Regions, 25 GB of storage, 2.5 million Streams read requests, and 1 GB of data transfer out. It is a strong option when you want a serverless NoSQL database with AWS-native scaling and global table support. Compared with Upstash, it offers a more traditional managed database path and a larger storage allowance, but the free tier is less straightforward for command-based workloads and does not match Upstash's Redis-style access model. Switch if your app already lives on AWS and you want a serverless NoSQL database first.

• Beats Upstash: Larger free storage allowance
• Falls short: Not Redis-compatible and less aligned with command-based access
• Who should switch: Switch if you want AWS-native NoSQL storage and global-table support rather than a Redis-style service.

Cloud Firestore's free tier includes up to 1 GiB of stored data, 10 GiB of network egress per month, 20K document writes per day, 50K document reads per day, and 20K document deletes per day. It is built for document data with realtime sync across clients, so it is a good fit for mobile and web apps that need structured document storage instead of command-based data access. Against Upstash, it gives you a generous always-free document model and clear daily read/write quotas. It falls short on Redis compatibility and the low-latency command interface Upstash is built around. Switch if your app wants document storage and sync more than cache or queue semantics.

• Beats Upstash: Daily read/write quotas for document apps
• Falls short: No Redis-compatible command interface
• Who should switch: Switch if you are building a document-centric app with realtime sync needs and can work within daily quotas.

Google Cloud's free offering includes a broad set of always-free monthly limits, including 1 e2-micro instance, 5 GB-months of standard storage, 1 TB of BigQuery queries, 2 million Cloud Run requests, one GKE cluster, 120 Cloud Build minutes per day, Firestore storage, Pub/Sub messages, and more. It also includes a separate $300 credit for new customers. Compared with Upstash, it has far more surface area and room to assemble an entire stack for free within service limits. It loses on focus, because you will need to piece together the right services instead of getting a single data API. Switch if you want the most free headroom across a broad cloud platform.

• Beats Upstash: Broadest mix of free monthly quotas
• Falls short: Requires piecing together multiple services instead of one datastore
• Who should switch: Switch if you want the most free room to build across compute, storage, and managed services rather than a single database.
