24 alternatives to Superglue – open source API connector that writes its own code

Hi HN, we’re Stefan and Adina, and we’re building superglue (https://superglue.cloud). superglue allows you to connect to any API/data source and get the data you want in the format you need. It’s an open-source proxy server which sits between you and your target APIs. Thus, you can easily deploy it into your own infra. If you’re spending a lot of time writing code connecting to weird APIs, fumbling with custom fields in foreign language ERPs, mapping JSONs, extracting data from compressed CSVs sitting on FTP servers, and making sure your integrations don’t break when…

Superglue is an open-source proxy server that connects to APIs and data sources, automatically generating the necessary code to retrieve and format data as needed.

    Last month, we open-sourced Supaglue (https://github.com/supaglue-labs/supaglue) as a developer toolkit for building customer-facing Salesforce integrations. Since then, we've been iterating on our approach with users and are re-launching Supaglue as an open source unified API, starting with CRMs. With our re-launched public alpha you can: - Interact with HubSpot and Salesforce through a unified REST API - Sync data from HubSpot and Salesforce into a local Postgres cache and make reads against a normalized CRM schema - Make writes (POST and PATCH) to HubSpot and…

    We spent the past few weeks building Supaglue (https://github.com/supaglue-labs/supaglue) and would like to share an early public alpha version with you. Supaglue is an open source platform to help developers build customer-facing Salesforce integrations into their applications. Use code to define syncs for pulling objects from Salesforce into your application. Embed functional and customizable React components for your customers to configure these syncs. Why? - We built user-facing HubSpot and Salesforce integrations in a previous product we worked on and did not find an…

    If you've ever worked in a large company, you've probably encountered "shadow infrastructure": scripts nobody understands or custom connectors written once and never touched again. This glue layer isn't documented, isn't owned by anyone, and tends to break when systems are upgraded or someone leaves. It's also the part everybody dreads working on, because it's hard to understand, painful to work with, and full of unknown unknowns. We built superglue so that engineers stop wasting time on deciphering legacy APIs and documentation. superglue ingests existing glue code, SQL, configs, docs,…

    We run superglue, an OSS agentic integration platform. Last week I talked to a founder of another YC startup. She found a use case for our CLI that we hadn't officially launched yet. Her problem: customers wanted to create Opps in Salesforce from inside the chat in her app. We kept seeing this pattern: teams build agents and their users can perfectly describe what they want: "pull these three objects from Salesforce and push to nCino when X condition is true", but translating that into a generalized hard-coded tool the agent can call is a lot of work and does not scale since the logic is…

    Hey HN! We built Notte, a browser infrastructure and agents platform. Many of our users automate UI workflows or extract data from sites that don’t have APIs. In practice, we noticed that once an agent understands how a site works, parts of the task can often run without a browser by interacting with the same network requests the site uses. So we built Anything API: describe a browser task, and our agent explores the site, builds a function, tests it against your description, and deploys a callable REST endpoint. No infra to manage. How the build works: - Describe the task (best results come…

    Hi HN, I’m Eoin, founder of Sourcetable (https://sourcetable.com). Today, we’re launching Superagents. You can now connect your spreadsheet to any database, API or MCP server on the Internet. All of that data is available inside your spreadsheet, and you can use AI to analyze it and build models, reports and visualizations. The reason I started the company is because I spent 10 years at startups across engineering and operations roles and realized that Excel and Sheets weren't architected for the modern information environment. This creates a tremendous amount of nuisance and…

    Hey HN, I’m Brad, one of the creators of Superblocks and a YC alum, excited to share our internal tooling IDE. As developers ourselves, we faced the problem of building tons of internal admin UIs, backends to connect siloed data, reporting jobs, and data pipelines. For UIs we would build one-off React components. For integrations, we would have to decipher vendor docs and implement auth. Finally, for reporting jobs we had to handle failures and observability – many hours of repetitive engineering effort. So we built Superblocks, an internal tooling IDE to connect to any datasource…

    Hi HN! Stefan here from superglue and today I’d like to share a new benchmark we’ve just open sourced: an Agent-API Benchmark, in which we test how well LLMs handle APIs. We gave LLMs API documentation and asked them to write code that makes actual API calls. Things like "create a Stripe customer" or "send a Slack message". We're not testing if they can use SDKs; we're testing if they can write raw HTTP requests (with proper auth, headers, body formatting) that actually work when executed against real API endpoints and can extract relevant information from that response. tl:dr: LLMs suck at…
